Hi!
Rooted with cmahendra's offline Lelus method (and to anyone who's done that, my hat is off to you).
**SHORT VERSION**
Sim goes into the L9. I get bars that show network availability, however I am not able to connect/make/receive phone calls.
**DETAILED VERSION**
Starts like this: I have my CM rooted Aria that works a-ok as far as the network. Phone message memory getting full all the time and incoming texts bounce back, with no way of knowing who sent them. Can't have that, so I buy a stock L9.
Sim works. I want to have Wi-Fi calling, which is the *only* reason I bought the L9. Wi-fi calling is not working: call up T-Mo and they say I need to give a 911 address and all will be well. Ok, done.
Sim works. But no Wi-Fi calling still. Call up T-Mo and they say "Ohhh! you need a "3G-B" (I don't think that stands for gigabyte) sim card" Ohhh and what's your phone model etc etc. I tell them "it's a no-brand phone I got overseas," they don't need to know the model: they didn't with the CM Aria. They're clicking settings on their screen other side of the phone while we're talking: I can feel it.
Sim *stops* working. Need a working phone, so let L9 aside and get a stock T-mo S2. Same issue, cell network not connecting.
Let me show THEM! Ha! I'll unlock it. Unlocked the S2.
Sim still doesn't work.
Put the Sim back in the rooted/unlocked Aria? Network works.
What settings do they have in their stock phones that disallow network connectivity, because in the CyanogenMod Aria I have the phone fully works, GPS, tether, etc etc. In their stock-from-T-Mobile phones, network = nada.
Thank you for reading.

What the heck are you asking? I don't see any understandable questions in your message. I see you blowing off steam.
It does look like T-Mobile cooked your sim. You may need a new one.
Call them again and ask for "Customer Retention" through the automated system. Those people are more knowledgeable. A new sim should be free if they killed it.
Also, a data plan is not required for wifi-calling.
T-Mobile will give you a SIM regardless. They are always free.
I'm not sure as I am unrooted, but most carriers block network access via files in the EFS folder. This folder is VERY delicate. Anything improperly changed here can render a phone useless. If the SIM works in another device, it's not the SIM. Have you tried a different SIM in your phone?
Also, if you're blocked from network access, when you make a call, you should be prompted with, "We're sorry, but this device has been blocked from network access." If you do not get that prompt, then there is something wrong with the phone itself, be it software or hardware.
Looks like the L9 isn't registering in their system. Where did you buy the phone, blacklisted perhaps?
As for fried your sim, why does it still work in the Aria.
As for 3G-B, you probably need a newer sim, others call it a 4G sim... They should send you one free or pick one up free at a local tmo..
Thanks so far folks...

You hit the nail on the head exactly clockcycle, it's not registering. Something *in* the phone is not letting it connect, because my sim works successfully in any and every other unlocked phone I have, blackberrys, GMS world phones, the rooted Aria, but in the two "newer-released phones-- the L9 and the S2-- it doesn't work.
Phones are legit. Craigslist and brand new. Worked perfectly until calling T-Mobile for "support". The sim is fine and the goal is to keep it and not get a new one. It works.
My strong guess is that if I put a different rom that is *not* stock, the phone will work fine. It worked fine in the beginning, until I called them to address the wi-fi calling issue and they started poking around in my account, asking questions and clicking on things. I didn't want to address the wifi-calling issue too much because we could go off on a tangent.
You're right kevev, it didn't look like there was a 100% clear question. A lot of story though, to make sure there aren't 50 posts of did you do this and id you do that. A full story gives everyone the most info they need to understand the situation instead of "yo! my phone is not connecting!" which we see sometimes .
So the more clear question is:
"I am experiencing carrier settings *in* my L9 that are blocking me from connecting fully to the network on a perfectly fine sim card, how can I get around these settings and what/where are they."
I think tribalartgod understands what I'm getting at most completely. The inside-the-phone-settings. When the sim is in the phone I have bars, but when going to make a call the screen message is "emegency only". Can't try different sims in the L9 because of the need to cut the sim down. Also the L9 is not unlocked, just rooted. My guess is a de-bloatwared rom is the fix. Looking for answers from people more knowledgeable than me which is most likely all of you. Thanks again!
Craigslist, new, boxed, doesn't gurranty they aren't blacklisted.
BUT, the Aria uses a miniSim, the L9 uses a microSim. Did you cut your Sim yourself? It might be misaligned, cut wrong.
It's less than $2 to get it unlocked..
It sounds like its IMEI blocked dude. This can happen with various insurance or installment plan scams, even to brand new devices. There are options to still use the phone, but you are hosed on T-mobile. I have a blacklisted L9 because the previous owner quit paying his EIP, but it's unlocked so I used it on an AT&T MVNO connected to an AT&T MicroCell (I wanted WiFi calling too, but that won't happen with a blacklisted IMEI). Until you've gone to T-Mobile's chat support and ask the if the IMEI is clean, writing long posts in this thread is futile, and it is pretty clear everybody in this thread THINKS they know what they are talking about, but nobody has simply asked T-Mobile about the status of the IMEI, which takes two seconds.
to day I stated to have problems with my internet on my SGP621 LTE I'm on T-Mobile and i'm getting the connect me messages basically t-mo want's me to get a separate tablet data plan. I was wondering if there is a work around so that I can use my tablet as a regular phone with data internet access without an additional data plan which I would not pay for. is there a way to make my tablet SPG621 to show as the regular Z3 phone and not as a tablet so that I can use the internet 3G/4G LTE thank you:crying:
I think that's just an offer. You don't have to do this. As far as i know you can use your SIM in any device you like. And ... Xperia Z3 Tablet Compact can be considered as a big phaplet.

I agree with nico_las. I use my SGP621 on T-Mobile USA as well, and it's not mandatory I switch over to a tablet plan. It's just an offer you can refuse.
Is there a way to refuse this offer? Like, my data no longer works as of maybe two hours ago, and I am not the only one reporting this. Can I refuse an offer and retain it? I called 611 but as usual the pre-paid support folk never know anything outside of their scripts...
the problem is that t-mo knows is a tablet and the internet wont work, calls ant and text does work but not mms and everything that requires internet, if any body know how to disguise as a phone/phablet like the z ultra by modifying the IMEI or something. thanks
Yes, I am currently Experiencing this Issue as well, and I told T-mobile Rep to stop forcing people like this. I can just sell this phone and buy a note 4, with smaller screen and it will work just fine.....but they basically want to force people into it, so they can make money out of it.
I am interested in how to disguise the tablet as a phone as well.
I really really want to kick Tmobile in the ass and never come back as a customer........but they know other carriers do the same thing......We are at the losing ends
we need to ask to devs if we can get help on this issue. what we need is to disguise out tablet as phone or phablet
I think you're being overly optimistic. I appreciate it. But we barely have support enough on this device to get a proper root, much less ROM support. I feel like it should be possible to pass this off as a normal Z3... But not sure. In any case it will take root at minimum and most likely an unlocked bootloader... Which I don't plan on pursuing until I know I can keep remote play, DRM, cast support, etc.
I hope it happens... And I'm with you... But I think it's a lost cause. I'd like to hear from an actual Dev about it though... Just not a lot of them in the English world with this tablet not on shelves outside of Asia.
Hey guys, a few thoughts.
First, there is chatter about this in 3 or 4 different threads. It doesn't have to be this thread, which I created yesterday, but we should band together and use a single thread for longer-term discussion.
Second, I actually don't think that this is an attempt by T-Mo to gauge more money out of us; we are a tiny percentage of their user base and are probably an attractive demographic for T-Mo in a sense. This is simply bureaucratic disorganization (I think they simply don't know how to provide 'free data for life' without considering the 621 a 'data only device,' damn you all who rallied for that), and unfortunately execs are not going to make an immediate priority of satisfying a tiny percentage of prepaid customers on cheap plans. What I personally expect will happen at some point, T-Mo will act in accordance with its 'uncarrier' mantra and be the first carrier to recognize that there is increasingly no difference between a phone and tablet. They will offer substantially the same plans for any data enabled device and will be the first carrier to officially support "phablets.'
Third, I am also very curious what can be done to trick T-Mo's system, in the mean time. I can say firsthand that altering the device model # inside your build.prop file will do nothing. Switching up the APN, nothing. But I didn't personally get that creative before giving up. One thing to note, on an older device, I downloaded a root app to ltyer my DNS servers (switched from T-Mo to OpenDNS). Within X many minutes of rebooting I could not make phone calls or receive texts and no data icon appeared either, but I did have data and T-Mo was probably unable to meter my data usage. Try at your own risk.
Fourth, *****ing accomplishes nothing. The great thing about buying unlocked, is the ability to switch carriers at the drop of a dime (which is coincidentally what T-Mo deserves from us right now). AT&T has LTE on four frequencies and the 621 supports all of em. I already made the switch to AT&T, and everything is smooth at the moment. And I can always switch back. As a light talker I miss my $30 plan (and the small $$ I had left over in my acct), but $60 for talk, text, and a tetherable 4 GBs of LTE isn't terrible when you can buy 5-10% off discounted refill cards from Calling Mart. Cricket is also on AT&T's network now and $60 will get you 20 GBs of <= 8Mbps LTE, $10 more if you want to tether without worry. I would be curious for an expanded discussion regarding our options, since I am only so familiar with the ins, outs, and possible pitfalls of them.
good one
Would anyone like to test for compatibility/pitfalls/etc on Harbor Mobile? $50/mo for unlimited talk/text/LTE and 3GB tethering on T-Mo's network, purportedly.
https://www.harbormobile.com/plans/
They also have a good looking tablet data plan ($15 for 5GB) that would be more useful if we had dual sim slots.
MetroPCS would be the other competitive T-Mo pre-paid option. Not sure how these companies detect phones/tablets. They don't offer free data for life, which might or might not make a difference.
Possible Solution?

I work for T-Mobile and have also have the same issues with my Z3tc I, being a store manager, have limited resources available to me but i plan to submit a ticket in hopes of resolving this issue, it would help if i had multiple issues to report however. If you folks are willing to help me out with this (power in numbers as they say) i think we may have a chance of getting a fix, what i need from each of you is your T-mobile telephone number that you've been using your Z3TC on and i can submit this ticket. Email your name and phone# to [email protected] and I'll do my best
I was about to e-mail Tyson, and just saw this posted (by a post-paid customer) to a T-Mo Support thread I had participated in:
"Just got off with customer service with the solution. To fix the problem you need to get a new sim card. The customer service rep said T-Mobile will provide them for free then everything should work fine. What happened is the info on the sim says its a tablet, once the sim info gets changed on T-Mobile's end there is no way to change it back and the only solution is to get a new sim card. Hope this helps you guys."

I don't think this is correct. I already got a new SIM for mine because that's what Tmobile support had me do originally. It didn't fix the issue. However I noticed under my account that it had my device listed as a Xperia Z tablet as in the old version when I got the new SIM. So maybe if you change it to a Z3 and get a new one it will work... But I doubt it.
The tech support I most recently talked to said they updated their systems with the Z3TC information and classified it as a tablet so the data won't work unless you get on a tablet data plan. But if I get on a tablet data plan then I can't have phone and text on the same SIM. He said there was no way for them to accommodate both.
And I tried explaining that the only difference between tablet and phone is phone capabilities... Which we have... So it should be a phone.
I see that more and more people are having this problem and being that t-mo knows that our SGP621 is a tablet the only thing to do is to disguise it as something else other then a tablet. I know that phablets do work fine like the xperia z ultra. we need some technical help on doing this guys.
Need more help

I've got about 5-6 people's info so far, if i could get 10 or so i think we could make some headway here. I have tried SIM swaps, tried using a regular z3 for a couple days and switching back, tried rooting and IMEI changing nothing has worked thus far... this seems like the best chance here.

I just ordered one and will be trying to use it on Tmo.
Just sent you my contact information, I'm also having the same issue with T-mobile.

This won't be a problem on AT&T's network. Why not just switch? For high data users, Cricket has competitive prices, for low use folks there are several mvnos to choose from.

Does anyone have an update on this? I think I got hit too. My internet stopped working this morning and I've been calling T-Mo and they said they don't know what the problem is.
New to this, but I'll try to explain the best I can.
I've talked to tech support from my old carrier, my new carrier, and Samsung for about 15 hours total. I'm getting absolutely no where.
I purchased a Samsung Galaxy A20 from Spectrum mobile 3 months ago. I ended my service with them and switched to Red Pocket mobile when they had their black friday / cyber monday sim kit deal.
When I activated and ported my number over to Red Pocket I thought there was an issue with the number port.
But going back and forth with customer service they couldn't figure out what was wrong, as my account was activated and they confirmed that they now owned my phone number.
Eventually I realized my device was still locked with Spectrum. They provided me with an unlock code which did not work. They suggested using the unfreeze code which worked, my device said accepted/unlocked.
Phone works, can make calls and send text messages. However,I cannot access data.
My network operator still says Spectrum, and my Access Point name says charter (Spectrum's APN).
I cannot select the Add button, or the Reset to Default button in Access Point Names.
I took this to mean that my device was still locked since the unlock code did not work.
I thought the unfreeze code was specifically for if you attempt too many unlock codes and it locks you out of making more attempts.
That was my understanding, that the purpose of the unfreeze code is to enable you to make more attempts with the unlock code.
Again, I'm not really sure.
But regardless, Spectrum insists that despite it saying that my device is still locked according to their information, that the only way for it to say unlocked on their end is if i actually connect to my new provider, but that they have done everything on their end and that my device is unlocked and I should be able to connect to my new provider.
FUNNY right... in their records it says my device is still locked, but that that's not really accurate, and that it should be unlocked.
However, I have Red Pocket's SIM in my phone. And I can place and receive calls/texts. Spectrum and Red Pocket both use CDMA, so that makes sense to me. But since I am routing through Spectrum still, and I am unable to Add Red Pocket's Access Point Name in my phone, I cannot connect to Data / LTE.
From what I've explained here, do you all feel like my device is truly unlocked?
What is the best way for me to bypass this? How do I get my phone to switch from Spectrum's Access Point Name to Red Pocket's Access Point Name so that I can access Data/LTE ??
Thank you for taking the time to read my plight, and I appreciate any assistance anyone can give me with this.
I am not sure if attempting to root my phone or messing around with those kinds of settings will fix anything. I am not familiar with how to do that, but I will try anything at this point.
I have the A20 under MetroPCS still locked to their network. I can add APN's to it. So not sure why you are having this problem.

My thoughts exactly. Very strange why I am not able to add APNs.
I talked to a Samsung representative who suggested that it is probably either a software issue or the firmware installed by Spectrum.
When I told the Samsung representative that they assured me that my phone is unlocked (although I don't believe they even know what they're talking about since it is listed as locked in their system), he even went as far as to say that my device may be SIM unlocked, but they may have installed some sort of firmware on their phone that locks the Access Point Name to their server forcing the user to stay with them. Thus the phone will be able to take a new SIM, but it won't do the user any good since the firmware installed on the phone will not allow the user to connect to any other provider's Access Point.
I asked the Samsung representative if it was even legal for them to do that? He said it wouldn't surprise him as corporate giants such as Charter try to monopolize markets. He then went on to tell me that Charter took over as the internet provider in his area about a year ago and no longer has any other internet service providers in his area to choose from.
But again, I don't know if this is actually the case. But does anyone have any thoughts about what is going on or any suggestions as to what other things I can try to do to get connected to my new provider?
A quick update in case anyone in the future is wondering about my issue.
So after talking with another Spectrum customer service representative I have discovered that although my device was SIM unlocked over 2 weeks ago, my device is still carrier locked. They put an initial request for a carrier unlock over 2 weeks ago. Then after calling technical support a few days after that they had put in another request for the carrier unlock. A couple of days ago the representative I talked to went through all of the previous activity logs with my phone and discovered that the carrier unlock kept getting stuck on the end process of unlocking. He opened up another case for me (this will be the fifth ticket created for my account), but I expressed my concerns and doubts with him that it will accomplish anything.
I explained to him that if the issue can not be resolved on their end that I am pretty much out of luck. Since I have discovered on several forums that the Samsung A20 US version cannot be rooted, so there is no way to unlock the bootloader and install Samsung factory firmware to bypass the carrier locked APN on my own. I explained to him that if there was a way for me to do it I wouldn't even be calling, and I would have fixed the issue myself. However, since I am pretty much out of ideas to get my phone to work with my new carrier on my own and Spectrum can't seem to figure out how to carrier unlock my device even though they are LEGALLY REQUIRED to do so, that I am pretty much just about to give up and sell this device as a carrier locked phone on Swappa. He said yeah that's probably what I would do too at this point..
I said LOL, yeah but the problem there is I spent over $200 on this phone that I was only able to use for 2 months, and if I go that route I will likely only be able to get $50 for it.
He said yeah I can understand that that's frustrating, but I really don't see any other options you really have.
They also refuse to provide me with any sort of compensation even though clearly the mistake is on their end.
Bottom line.
NEVER BUY A PHONE FROM CHARTER / SPECTRUM.
Considering their business practices I would never buy phone service / internet service / any service they offer in the future, and would highly advise everyone else from ever purchasing anything from them in the future.
I have a palm phone since yesterday and I am running through a mayor problem. I live in germany and bought the phone from a german private seller from ebay and he hided the information that its not the european model but the verizon model from the US. Its not even unlocked (verizon boot screen).
Problem: mobile internet, messages and phone calls
I replaced the standard apps for calling and texting and after some restarts it was possible to get both calls and messages. Mobile internet also worked, though its only 2G. However, after a short time mobile internet, messages and phone calls stop working. After a restart it works again - at least most times. But again only for a short time.
Any solutions for these issues? Restarting the phone every half an hour or so cant be the only way...
Nobody using an US palm in Europe?
I had the same issue when I first got it. It could be related to the incorrect/absent APN (Access Point Name). Usually you can get hold of them by contacting your network provider (should probably be on their website). Once I was able to set the correct ones up, I started getting 3G. Haven't been able to get 4G nor LTE just yet despite the phone being capable of supporting this.
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.

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?

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.

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).

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.
