Verizon Service Issues on LG V30+ with custom roms Installed. - LG V30 Questions & Answers

So, I've got an LG US998 that I have Unlocked the bootloader on to try out some custom roms with. Every thing works fairly well and I'd love to stick with a given custom rom for more than a day to really try them out. However, so far i've had no luck with that because of an issue I'm having with Verizon Services. So lately, I've had to stick with Stock US998 or VS996 for now.
The problem:
On any custom rom (yes, even stock based ones like BoomBox/AIS etc...) I cannot send or receive SMS messages, MMS messages, or receive Phone Calls and their respective Visual Voicemails. I have 4G LTE connection with expected signal strength. The LTE Data works fine (ie. I can browse the web over 4G etc..) and calling some one from the phone also seems to work fine.
The catch:
A brief moment after completing a successful call with anyone, I can enjoy about 5 minutes of everything working perfectly! Text messages I missed start rolling in, missed calls and their respective Voice Mails sync up. and text messages pending to be sent get sent successfully. Even MMS messages work fine. I can enjoy about 5 to 10min of this before the phone returns to the previously mentioned behavior without warning.
I have looked at the forums for people with a similar problem for quite a bit over the last week or two and haven't found people with my exact problem. Is this something I need to take up with Verizon themselves? But their service works flawlessly on stock US998 and VS996 firmware so I don't see how it could be with Verizon. I'm at a loss
Any one with some insight? I'd really appreciate it.

If it was just texts, I'd ask if you're using Textra. There's a setting Verizon users need to change. But it has to be something else. I know they're other Verizon users on custom ROMs in this forum. So it has to be something with your setup?
Sent via open market LG US998 V30/V30+

I faced the same problems with vs996 to 998. I gave up trying to get a rom to work right. Something is going on and don't think there's a solution. Changing modem.bin, APN settings, etc doesn't keep connectivity. I've searched and don't think there's a solution. I just gave up and living with stock root. Hopefully someone can figure this out.

Over the weekend I was able to test my phone in another state and found no change in the behavior. I'm inclined to believe It may be an issue with my SIM or particular phone hardware. I'll keep messing with some things as I think of them and try to see If I can learn more.

Texting Stopped Working on EVO LTE

I suddenly can't send or receive any text messages. I don't have a clue what caused it. Last night I installed the app wifikill and used it for a few minutes which did cause my phone to reboot and for some reason made it look for a profile update, firmware update and prl update. Everything else seems to be working, so I'm not sure what's going on. I already attempted to delete everything in my phone and restore from a nandroid backup before this happened, and the problem still persist. Any ideas of what could have caused this and how to fix it?
I don't know if it is related or not, but I've been having texting issues with the LTE as well. Sometimes they go through, sometimes they don't and I end up turning airplane mode on, then off after waiting 30 seconds.
I've also been having MAJOR delays in getting sent messages (some are coming in more than 2 hours after they were sent to me according to the time stamps on the incoming messages)
It is really driving me crazy (oh, and along with data crapping out as well with no rhyme or reason as to why and when).

+1 to this issue.
That's no really the same problem I'm having. I simply can't send or receive text messages at all. It just suddenly started happening with no warning, so I'm not sure what caused it or how to fix it. Please let me know if anyone else is having this problem. If I don't hear anything soon, I'm thinking about unrooting my phone and re-locking the bootloader and taking it to sprint to see if they can do anything with it.

I would run the ruu which will put you back to stock and see if the problem remains.

Sadly I already did that, and it still wasn't able to send or receive text messages. But here is the real kicker. Soon as I made a call to one of my friends who also knows a lot about phones to ask him if he had any suggestions, all the text messages that I made that wouldn't send all sent. By simply making a phone call, the phone must of connected with the sprint towers and made it start working. Super bizarre, but it's working again. So now I'm in the process up setting everything back up. Thank you Titanium Back up.
I'm currently experiencing modified version of your problem. I can't send text messages, but I can receive them. The only messages I can send are picture messages because they are looked upon as data.

Are you new to Sprint? Text messaging on Sprint has done this on several different devices for the past two years (since I joined Sprint). And when I make a phone call several tend to come through.
Oddly enough this doesn't happen in Utah when I go to visit, only Puerto Rico (where I live).
Try making a phone call and updating your prl within Sprint Zone. That fixed it for me.
I tried EVERYTHING to fix my phone. I rooted, unlocked and installed 2 different ROMS. None helped. I had to update my PRL every hour, and sometimes that didn't help either. I wiped everything, unrooted and relocked, ran RUU and went to Sprint. They replaced my phone. They are not allowed to work on these phones currently, so you'll either get a new one or a reconditioned one. Because I signed up for insurance, I got a new one.
I have not had any of the same issues since getting a new one. To me, it seems the issue is the PRL. It's showing that it's been updated, but it's not updating. There's a conflict between what Sprint sees on their side and your phone. But.. I'm not a Sprint tech, so I don't know.
All I know is I have a NEW phone and the problem is FIXED. For now anyways..

Actually know, I've been with Sprint close to 20 years now. I've always had a lot of different problems with them, but I've never had this particular problem before. But I'm glad I got it figured out, and everything is working again.

SMS problem on Cricket 4G with SCH-i545 on OTA OC1

So about a week ago I switched from Verizon to Cricket with my SCH-i545 that I foolishly updated to OC1 through OTA before leaving Verizon *doh, what a dummy I am*. I have had a persistent problem with sending SMS messages when connected to 4G LTE and I am not sure what else to do, here's what i've done up to this point.
1. Checked and rechecked a thousand times the APN settings of the phone, they are exactly as listed on the Cricket site.
2. Contacted customer support VIA zendesk, checked my APN settings again, had the customer service member "refresh" the signal to my cell phone and after that didn't work he shipped me a new SIM card because I wasn't able to access the "message centre" to check my SMSC number like you can on most S4's due to VZW's restrictions (cant access it through dialer codes either, those are also restricted). Got the new sim, he activated it, still doesn't work.
So, I guess my question comes down to, HOW IN THE WORLD can I view and edit my SMSC number is that is the culprit (which I think it might be). My wife has ZERO troubles with her phone and has the exact same setup except she didn't upgrade (thankfully) to Lollipop OC1.
Hopefully someone out there has dealt with this already and I have just missed it although my search hasn't turned up anything. Sorry that i'm not more well versed in the lingo for this type of stuff, and I hope my post is easy enough to understand.
I really hope I won't have to just get a new phone.
Me too
Stuck in the same boat as you. Either waiting for T-Mobile to release their lollipop update or hope for a root so we can get back off the OC1 update. Luckily my GF has a backup phone while we wait for people smarter than us to come up with a fix

Yep, I just wish I could LOOK AT the SMSC number, that would at least tell me if that is what the problem is or not.
That or disable the freaking 4G LTE so I can send a message. Never again will I OTA an update, lesson learned. Thing is that my wife is on the EXACT same setup, just with the old kitkat instead of lollipop and her SMS works just fine on the same S4 on 4G LTE. Sigh, IDK.
SCH-I545 + Lollipop + Cricket = No outgoing text + no keytones from dialer
Had same issue + no keytones on dialer so can't check VM. I just about bricked my phone trying to resolve it and lost the mk2 BL in the process, could not go back to JB or KK. This was a disaster. I found elsewhere people taking their SCH-I545 to TMobile has same issue. My only conclusion is that the VZW firmware nazis clamped down harder and harder with every OTA until you can't take your phone elsewhere. My XO with identical phone is still on JB with Hyperdrive and has no issues. I won't be upgrading her phone.
I am just about ready to go office space gangster on my VZW + Samsung product. My only recourse with this phone is to get Google Voice, which I have done for exactly $0. On a Cricket group plan with 5 people I only pay $24/mo for 2.5GB of data so if you have 4 people you trust to pay their bill on time there is no better deal. We'll see if that is enough with GV, it probably will be. So all Cricket is to me now is an LTE service and I can use any carrier and my carrier number doesn't matter anymore, it's just a gateway. So if you don't mind assimilating into the Borg GV has some real benefits and will resolve this VZW issue.
In the meantime, I am setting aside the $ I save on Cricket and I will buy an unlocked phone from HTC or LG or Moto when it is time and go CM and never look back.
I'm in the exact same situation with VZW GS4 going to Cricket. Unless I had a lapse in reality, I got an SMS/MMS to go through the very first attempt and not since. That makes no sense. I still receive SMS. And, I get calls. But, sometimes outgoing calls try to send as International.

Good data signal strength to poor call strength?

My question/problem. What/why do I have a good 4 bars (of 5 bars) of data signal normally, but, when I decide to dial and make a telephone call, the signal strength goes to barely one bar as soon as I hit the dial button on the phone? I have not moved myself or the phone's location. The call may dial, but goes in and out and, more often than not, drops the call. At the same time, if I receive a call from someone, it is normally a much better signal, and does not drop or go in and out.
I am on Verizon phone (vs996) Frankenstein to us998 30b (pie). I have recently tried android 10 roms (Havoc, POSP). I don't know if that has anything to do with it or not? Very frustrating when trying to call someone.
Any thoughts or explanations or, hopefully, fixes?
Thx

If you are using Verizon on US998 firmware, then you don't have access to VoLTE (which is phone calls over LTE, Voice over LTE). LTE started out as a data-only service but for actual phone calls, carriers were still using 3G HSPA or CDMA (Verizon, Sprint). When making a phone call, phones temporarily bump down to 3G, and then jump back to LTE after the phone call is over.
With the VoLTE protocol, that finally allowed phone calls with LTE. It added VOICE capability to LTE.
However, different carriers treat VoLTE differently. T-mobile allows VoLTE and Wi-Fi calling for US998 phones, while AT&T and Verizon are more stingy. They reserve VoLTE mostly for their branded phones running their carrier firmware.
I'm an AT&T customer and I've never had VoLTE because I've never used a branded AT&T phone. For me, on AT&T, when I make a phone call I am bumped down temporarily to AT&T HSPA. Then, after the phone call, it jumps back to LTE.
If I were to flash the AT&T TWRP flashable zip, possibly I could enable that. But it's not just firmware, it's also a setting on the carrier side that has to be enabled.
Bottom line, what's happening is you are seeing you STRONG LTE signal. But when you make a phone call, you are being temporarily bumped down to Verizon CDMA. However, Verizon is in the process of dismantling all their CDMA towers. That's why your CDMA signal is so weak. Verizon plans to shutdown CDMA entirely by end of 2020. After that, you will need VoLTE to make phone calls on Verizon.
Since you have an actual VS996, you can flash the VS996 TWRP-flashable zip. Once on that firmware, see if VoLTE is enabled on your account (carrier side setting) and see if when you make phone calls you stay on LTE and are not bumped down to CDMA?
Thx, Chazz. So, it's a Verizon thing? Not necessarily something I caused by going back and forth trying out the different Android 10 roms. Good to know. I will try the 996 rom later today, since I don't need the Hotspot for a couple of days. As always, you've been very helpful, thx. :good:

Yes, especially if you see strong LTE signal before making the phone call. Control freak Verizon (mostly) only allows VoLTE on Verizon firmware with Verizon branded phones. There may be exceptions (maybe Pixel phones?) and I know the ZTE Axon 7 (not a branded Verizon phone) somehow got VoLTE not only on ZTE stock firmware but also on LOS ROM -- but I believe ZTE paid Verizon to allow that. It's the exception that proves the rule.
Here's a a more in depth article about Verizon CDMA being shut down end of this year.
https://grantcountyreview.com/content/verizon-wireless-postpones-its-shutdown-3g-cdma networks
when Verizon closes its 2G and 3G networks at the end of 2020, 3G phones will become obsolete and non-VoLTE LTE phones will not be able to make or receive calls.

You DO have a Verizon VoLTE capable phone -- a Verizon VS996 -- but for V30 only on Verizon firmware. If you were using T-mobile with US998 firmware, you would have no problems with VoLTE or Wi-Fi calling. T-mobile is more open than Verizon about such perks.
I don't get VoLTE with AT&T on US998 firmware, but AT&T has no plans to end 3G HSPA anytime soon.
Chazz, I thought I would give a quick update. Late Last night/early this morning, I switched to vs99630c. I have made two phone calls, one to Florida, one to Washington state. Both connected and sounded so much better than when with the us99830b Rom. Even though both dialers had a little HD in the upper left hand corner. This Rom kept the same 3 or 4 bar designation for the signal strength. Much happier with it. Even though I don't have a hotspot (may have to pay the $10(?)or so to set it up, if I decide to stay on here.
Also, I have just seen a 99630c debloated Rom someone has made, that I might try in the next day or so.
I so wanted to try the android 10 Roms, but I just had too many small issues (reboots, no hot spot, system ui crashes, etc.).
Thnx, again for your help and guidance.

Then you are now probably using Verizon VoLTE, which is using LTE signal -- not the increasingly degraded CDMA signal Verizon will completely shut off December 31, 2020.
Verizon is probably already deprecating those towers -- leaving just enough, like when you're on the highways.

I really want volte and vowifi for my unlocked us998. The only way to have that is to flash the vs rom, which is 30c? I'm on US99820h, what do I lose by going to the vs rom? Is there a vs 20h variant?

Yes, we have Oreo VS996 KDZ. It's actually "20k", because it took Verizon two attempts to fully release LG V30 Oreo. And they released a couple extra updates for Verizon related bugs. So, although it's equivalent to US998 20h, it's a higher letter.
https://forum.xda-developers.com/lg-v30/development/vs996-lg-v30-verizon-vs996-t3865398
You need to have VoLTE enabled in your Verizon account, besides flashing this firmware. It helps to have it already enabled from a Verizon branded phone. But sometimes a helpful store rep willing to bend the rules can do it for you.

I thought the Pie variants were not great, lots of broken features? Or was that just the US998 versions? What were the tradeoffs to staying on Oreo?

You asked for Verizon Oreo equivalent to US998 20h and that's what I gave you.
I'm not recommending Pie for US998.
Verizon Pie may be a lot better. I don't know. Someone using Verizon Pie will have to answer.

I misread, somehow thought the ROM you linked was Pie. My bad. I know dirty flash is never recommended, but could I get away with it here? What do I lose by going with the VS ROM over the US998? Apparently the only things I have to gain are VOLTE and possibly VVM?

Do you have VoLTE already enabled in your Verizon account?
You'll lose the no bloatware experience, but you can fix that with Titanium Backup.
As for dirty flashing, you can try... If it doesn't work, then you have to factory reset and clean install. Don't forget to reflash Magisk.

I logged into my VZW account and after 8745 menus, finally found the HD Voice section. It says it's "Active", so I should be good for the VS ROM yes?

Seems like, yes.
I had to do a few steps to manually activate HD/VOLTE on my VS996 phone when I was on VZ. I documented the steps somewhere here (using ShortcutMasterLite). I know at least one other member here used the same steps on his phone. I'm thinking you'll be fine once you're on VS996.
I have not switched to Pie... still running Oreo. I have heard too many issues with Pie, so I have no desire to bother. I can't imagine VZ's Pie release is any better than Pie US998. VZ is too lazy to do anything else right, so why would they bother fixing what's wrong on US998.
Just want to quickly update this thread. I dirty flashed the VS99620K.zip in TWRP, then immediately flashed the latest Magisk zip. Everything updated perfectly, installed about 10 VZ apps, and I now have VOWIFI (and can send/receive texts!), though haven't been able to check VOLTE as I'm currently in a dead zone.
I'd already had HD calling active on my account, but can't select the option to also enable Video Calling. It says I need to contact support. I chatted multiple times with VZ support who claim it's active, though every time I try to enable it, it gives me the same error. What is this option, and do I need it? I'm pretty sure I was able to use Duo, Skype, Zoom, etc before the ROM update, am I spinning my wheels here?
Also, independent of this upgrade, my motion GIFs in any text app don't move. I thought it might have something to do with the non-VZ specific kernel, but after flashing, still just shows a static picture.

Are you the account holder? Some people can't get to it as they are just user.
https://community.verizonwireless.c...video-calling-feature-is-disabled/td-p/853001
I'm not sure what Verizon video calling is. I'm guessing some Verizon-only video chat -- like Apple's FaceTime is only for iOS? If you are already using Duo, Skype, Zoom, it would seem you don't need it. But you do make sure you have voice over LTE (VoLTE, called "HD calling" Verzion) --before end of this year.

I am the only user on this account, so definitely the account holder. After more wasted chats with VZ, they said that since my phone is not VZ branded, it's not eligible for Video Calling, which apparently is exactly as you described; Facetime for non-iphone Verizon users. I don't need that, as you said all my other platforms work fine.
How do I determine if VOLTE works? Like I said, I'm in a dead zone now, but going out to a good cell region in a few hours and can check then somehow. I did confirm that I can make calls and text over WiFi, so that's half the battle. How to check VOLTE?

I think if you have Vo-WiFi that means your VoLTE is also activated. They seem to be packaged together.
If you make a call in a good signal area, see if the "4GLTE" icon stays on when you make the call. It may even change to VoLTE icon? or HD calling icon? A Verizon user can probably tell you better. But the key is to see if there are any status bar icon changes and what they are. Also see if there is any information in the dialer GUI during the call, where you click on the dialer timer.
Yeah, don't talk to VZ. They're too stupid to help and downright liars. Your phone will work fine on their network even if it's not VZ branded (I've used US998 and H931 phones on VZ without issue).
On my phone, I did have to do some setting changes in SML (ShortcutMasterLite) to get VOLTE working. I don't think most people have to do that, but I did... and I agree, I think that got VOWIFI working as well. I'm guessing you have both, too... just need to try it. If not, you can force-activate it as I documented earlier (via SML).

Messaging and Call issues when attempting to flash android 10 roms

I'm pretty new to both rooting and this website, so I apologize in advance for any newbie mistakes I'm gonna make.
Background:
I have a VS-996 which frankensteined and unlocked by following this post . After doing that I flashed pie and then flashed lineage os from here . That rom wasn't very stable and kept crashing, so I tried others. I wound up going with Havoc OS. I believe it was in 3.4 when I first flashed it. I've kept up with the updates up to 3.7.
The Problems:
Havoc OS works fine for me, very stable, except for some reason phone calls and messages(both sms and MMS) are spotty at best. Sometimes texts won't send at all, or they'll act like they sent but the text won't be recieved. Sometimes my phone will say I can make emergency calls only. Group messages and sending pictures don't seem to work at all, at any time. These issues seem most prevalent immediately after booting my phone up. Data works perfectly except sometimes when the phone doesn't like to register that the SIM is inserted for a little bit after booting up.
What I've tried:
I've tried reinstalling the rom.
I've tried installing different Android 10 roms.
I've tried going through the process again starting at the the Frankenstein method and going from there.
I've tried messing with the apn
If I flash back to a stock pie ROM everything goes back to working perfectly, and I'm using my sim in my old V20 while I try to sort this out, so I know the SIM is not to blame.
I've been unable to find anybody else with this particular problem, though that could just be because the problems cover so many different aspects that I'm not sure exactly how to search for answers.
Any help is appreciated, thanks.

Are you Verizon customer? You say you have VS996.
There's an LOS ROM bug for Verizon SIM card users where upon rebooting the phone you have to make a phone call first to then receive texts. This phone call "registers" the SIM card or whatever. Many people call their voicemail number to satisfy this requirement.
This bug affects all LOS-based ROMs.
Yes I am a verizon customer. I had noticed that making a phone call seemed to help things along when messages wouldn't send. I guess I managed to let my phone die or turn it off enough to hide the fact that it fixed me. Giving it a test just now it seems to be working correctly. I don't know if I'll be happy or mad if the solution turns out to be this simple.

Was noted extensively on LOS-16 ROMs, but not discussed as much with LOS-17 (Android 10) ROMs. But earlier this month someone in the Havoc 3.7 (LOS-17 based) thread did bring it up...

Would anyone happen to know a fix for the having to make a call on verizon to receive incoming calls/text messages-
It's the main thing preventing me from running any android 10 rom. Have an unlocked (True) US998

However, the larger problem is in six months you will not be able to use LOS-based custom ROMs with V30 on Verizon.
* As of December 31, 2020 Verizon is dropping 3G CDMA to repurpose bandwidth for 5G.
After that date, to make any phone calls on Verizon you will need VoLTE. No LOS-based custom ROMs have VoLTE. You will need stock Verizon firmware. It can be rooted stock firmware; you can use Magisk modules to add features -- but needs to be Verizon firmware for VoLTE.
* T-mobile users are in the same predicament.
In January 2021, T-mobile will be dropping 3G HSPA for same reasons. T-mobile users will need VoLTE, which only comes with V30 stock firmware. However, T-mobile is less stingy. They also allow US998 firmware to have VoLTE and Wi-Fi calling with T-mobile SIM. Whereas Verizon requires Verizon stock firmware, and it needs to have been activated on a phone with Verizon IMEI at some point.
* AT&T will also eventually drop 3G HSPA -- but not until February 2022 (18 months from now).
So, for U.S. V30 owners who wish to run custom ROMs a little longer, you should check out AT&T Prepaid. It's a lot cheaper than "regular" AT&T, but is only for people who own their phones.
18 months is a long time. Anything can happen in 18 months!
AT&T only gives VoLTE to AT&T IMEI phones, as well as iPhones and some other phones I would never own. I've never used an AT&T branded phone on AT&T. I'm an AT&T customer with three native US998 for myself, my wife, my mother -- so I'll cross that bridge when I come to it in February 2022. Will probably give my mother an AT&T V35. Maybe my wife, too. Also, LG may get their act together and produce a good phone fro the LG V70 or LG V80.
Any Verizon, T-mobile (and Sprint), and AT&T MVNOs (Straight Talk, Ting, etc.) will also be affected by these decisions.
I have a more extensive discussion of this issue here:
All U.S. V30/V3O+/V30S will need stock firmware, not LOS-based custom ROMs. When?

Emergency Calls Only on LTE

Hello!
Can someone please help me with this?
Everything was fine until 2-3 days ago. When all of a sudden I was unable to send text messages or make phone calls. All the while I could access internet without any issues.
If I switch to 2G or EDGE for the Subnetwork, I can make calls and send SMS.
How can I fix this?
Could dropping the phone have caused this?
Dropping could certainly break something, of course, but let's assume that's not it.
What carrier? Is the phone officially supported by them (ie, IMEI matches the carrier)? Are you on their official ROM? Does/did your VOLTE work (before and after the "few days ago")?
Some carriers are switching over to VOLTE-only setups, so they may be testing that to see what works/doesn't before they make it final. In other words, maybe your phone is not "officially" supported by VOLTE on the carrier, which is why it's failing? Without VOLTE, I think text may fail as well (even if you're not actively on a call?)
That would be my first guess. In my case, for example, I was on a US998 phone (per IMEI) running VS996 on Verizon. Since the IMEI didn't match a VZ phone, they refused to say it was compatible (even though it worked fine for many years). The IMEI stuff is a bunch of BS, but that's a whole separate topic... but I wonder if this is what you're running into. It's the carrier's way to force you into "their" device, even though it's not any different from any other variant (when the proper ROM is installed).

Carrier texts should theoretically still work as they are "data". It's the "voice" part of VoLTE that won't work. That's why I can still receive carrier texts on my Galaxy Note 9 with AT&T -- which still has older firmware (so I can be rooted). A few months ago, I lost the ability to make/receive phone calls on my AT&T number when 3G towers were decommissioned in my area... But luckily I have Google Voice number, which also uses "data" (VoIP) so I make/receive all my Google Voice phone calls. (That's been my main phone number for years.)
However, I no longer can make/receive AT&T phone number calls -- which is fine. I switched Google Voice settings to data/Wi-Fi only instead of piggy backing on carrier phone number. Yet, I still receive AT&T texts, which is good because my bank insists on using a "real" (carrier) phone number for SMS security code confirmation.

You are in Portland? What carrier are you using that still has 2G and Edge?

I'm with a company that uses T-Mobile towers. I connect just fine with 4G LTE, and get reasonably good speeds over it. But when I'm on 4G, I cannot make or receive calls or text. It says Emergency Calls Only.
So far, I've tried everything. I resettled network. I looked for different APN values that may fix the issue. When I couldn't think of anything else, I did a factory reset. (I mean, I wiped Data, and all other partitions in TWRP except for System and SD Card.) There have been no changes.
I'm starting to think the issue may be hardware, I did drop the phone a couple of times the day it stopped working. Though I usually end up dropping the phone once a day or every two days. I can't believe the screen hasn't cracked yet, at all. Could a drop from 3-4 feet on hard surface like tiles damage the antenna in such a way that only 4G data works?
I'm ready to give up and buy a new phone even though I can't really afford it. It would be awesome if I can get this to work.

I'm on T-Mobile towers with the US998. I don't think there is an issue with IMEI. How would I connect to data with 4G if that was the case?
I never had Volte on this phone. I do recall seeing it when I first got it but I'm running stock rooted Android 9.
When I say it used to work a few days ago, I mean it just stopped working at one point. I wanted to make a phone call, and all of a sudden, I couldn't. I noticed then that it says Emergency Only sign, so I walked around the house for about 15 mins to try to get signal. Then I went to my car and drove around, but nothing.
I messed around with Network settings, and figured out that Voice and TXT worked when I switch to a lower 'Sub-Network' setting that says, "GSM / GSPR / EDGE Only".
To get 4G Data back, I have to switch it back to "LTE/Legacy 3GPP multi"
These two are found under "GSM/UMTS Settings", after clicking on "System Select" in "Mobile Networks ".
I want to also mention that my carrier website has been talking about a data migration that would affect phones using their old SIM Card.
When I saw that, I called them and had them send me a new SIM. I thought surely this must be it, but the new SIM works exactly like the old one.
Perhaps the migration or whatever it is they did that required new SIM cards just doesn't work well with my phone? Even though, before putting the order in, the rep I spoke to did check my IMEI and said that my phone is compatible.
Agreed, it doesn't sound like an IMEI issue.
FWIW, I showed a 4G connection on a phone (I don't remember if it was my V30 or a Galaxy S10+ that I was going to replace it with). On that phone, at one point, but there was no actual connection. So, the indicators aren't always accurate. That's why I thought maybe the data isn't really working, and if data isn't working then VOLTE won't work... and with many of the carriers switching off non-VOLTE calling, that could kill the ability to make calls?
In your case, you said data worked... but if VOLTE was never enabled, and the carrier dropped non-VOLTE, then, again, you may lose calling.
In any case, these were my theories. I think you're on top of the situation but I don't have any other ideas for you to try...
Instead of buying a new phone, have you considered installing and setting up Google Voice, as ChazzMatt said? I recently had to do that because AT&T's 3G shutdown meant that I could no longer place or receive calls. My quick guide on doing that is here: https://forum.xda-developers.com/t/...-based-custom-roms-when.4138223/post-87342453
I don't know why you can't also send or receive texts, but the Google Voice app has the ability to do that, so maybe try using that after you've set it up.

There's been reports T-Mobile which is now merged with Sprint has borked the ability for VoLTE/VoWiFi calling on US998 firmware phones (native or Frankenstein'ed). Apparently they only allow it now on T-Mobile H932, whereas pre merger they were happy to give VoLTE and voWi-Fi calling to "US998" phones
First, it was reported with new SIM cards they were distributing earlier this year. Then people who kept their old SIM cards found they didn't work after a forced "security update."
This seems to have also trickled down to the T-Mobile MVNOs.
This is why we told someone else recently they should probably convert their phone from US998 on T-Mobile to Verizon VS996 firmware.
Then get a Verizon sim card or Verizon MVNO SIM card, and activate it in an old cracked screen Verizon phone off eBay, then put that already-activated SIM card into their "VS996" V30.
They will have VoLTE and VoWi-Fi calling.
Alternatively, if you really want to stick with T-Mobile network, you can do what @osprey00 suggested -- which is get a Google Voice number and use it as a tool to forward your carrier calls to it.
You can read his post, see his experiences, and see if this would apply to you.
For ME -- I've been using Google Voice for the past 10 years as my main phone number. I ported my carrier phone number at the time to Google Voice. Then got throwaway carrier numbers (whoever had cheapest plan) but never gave those to my friends. To my friends nothing ever changed. I've had the same "number" for the past two decades.
But within the past couple years, I had to start giving my bank and my cable company my carrier phone number for SMS security codes. Very annoying, because in the past they used my Google Voice number to text me with no problem.
So, even though under my current firmware (on my rooted Note 9) I cannot get carrier phone calls, I still have LTE data. And with the LTE data, I can use Google Voice (calls and texts) because it's VoIP. I also get AT&t carrier texts, as that is also data. It's just AT&T phone calls I cannot send or receive.
AT&T deactivated the SIM card in my native US998 V30+ and sent me a replacement phone, which is a Samsung Note 9. I'm staying with AT&T for a reason. Otherwise I would probably pull the "V30" Verizon trick also.
I bought both my wife and my elderly mother 64GB V35 phones -- which is basically an upgraded 64GB V30. (They previously had native US998 V30.) AT&T gives V35 VoLTE and WiFi calling, and for them there was nothing new to learn.

I think it was a hardware problem, honestly.
No matter what I did, I even tried different ROM to ensure I didn't mess around with root settings and somehow enabled or disabled something that I should not have. I tried flashing stock radios, and no, nothing would fix it.
I took my brothers phone to see if the SIM card would work with his phone, an unlocked Google FI phone. As soon as I installed the SIM, and booted up the phone, I could tell it was working perfectly even on the lock screen. Right away the status showed the name of the wireless company, and active 5G data icon on the status.
I must have damaged the internal radio or the LTE data modem when I dropped the phone last. The screen of the phone never broke even though I dropped the phone countless times, though the back glass has cracked lines all over even if the surface is still smooth and the phone continued being waterproof (I tested).
Anyway, I have since bought a new phone and the Data/Text/Talk all work perfectly on it.
I'm not sure what I'll do with this phone, as selling it wouldn't be ethical. And I doubt anyone would buy a phone with the warning that service may not work.
Ah well, I may just keep and use it as a test device.
Thanks to all who tried to help.

tried a rom on a j7 2015 because android 6 is going to be left and I only get emergency calls on lte and on 3g, no problem. It's not imei problem maybe exynos processor. I went back to 6.0.1 and no problem with 4g lite. By the way, I'm not in the USA.
