Sprint WiFi Calling (Calling+) on Non-Sprint ROM?? - LG V30 Questions & Answers

Mostly thinking out loud here:
Would it be possible to get Sprint's WiFi Calling/Calling+ feature working on a Non-Sprint ROM?
Device was converted to US998 for bootloader unlock and somewhat "converted" back to LS998 by flashing Sprint Modem.
I have a work phone I use on a daily basis and would allow me to use my personal phone (V30+) as a tester if someone wants to take this on. I would, but I don't believe I have to skills to do so safely.

Well there is a VOLTE module in the Magisk repository but idk if it would work on lets say the stock US99820a-20d Rom (depending on the one you cross flashed to) or Lineage OS and the other ones based on it, you would have to flash the module and check for yourself...

What are the advantages of flashing a US998 to VS996?

I've been rooting since my OG Droid days back in 2010 but this will be my first foray into the LG world. I've read ChazzMatt's & TxanMoe's guides several times (much thanks to you guys!) but I'm still a bit confused on what the advantages of flashing a US998 to VS996 is.
My eBay 9/10 "Like New" US998 V30+ arrives tomorrow and I've already downloaded the drivers, LGUP, and the files in ChazzMatt's guide.
I don't want any of the Verizon apps on my phone. Is there any advantage to flashing VS996 and then uninstalling/freezing all the Verizon apps? Does VS996 provide anything other than the Verizon apps that come on the Verizon V30?
Thank you in advance for helping an LG newb.

I'm not a Verizon customer, but stuff like Verizon voice mail, WiFi calling are what are commonly mentioned. There may be ways of getting that without flashing the VS996 ROM, I don't know.
Verizon users can chime in.

Pretty much everything ChazzMatt said. There are some guides to getting WiFi calling working for Verizon, but I never got any of them to work for me (and not for lack of trying, I did every suggestion). Once you flash VS996 you'll be able to use the WiFi calling and get your visual voicemail. And because you have root, its not too bad to just totally uninstall all the Verizon bloatware apps. Given that I was running a stock US998 ROM anyway, there was not reason not to switch to VS996. After uninstalling Verizon apps with root, its the same as stock except WiFi calling and visual voicemail work.
Hope that helps.
Thank you very much for the info!
I guess I'll flash the VS996 and start uninstalling.
Playing around with my LG V30 for a couple weeks now with the stock Verizon ROM and its really not bad at all. It does not feel constipated with bloat and runs fast and snappy. I disabled quite a few apps thru settings and installed the apps I wanted without issue complete stock. Battery life really kicks arse. I prefer the Verizon VM and visual VM so I will keep it stock for a while or until it does something I cant live without then void the warranty.

That also includes Advance Calling too? I'm editing my WTF guide to recommend flashing the @westwood24 TWRP flashable file after bootloader unlock and root. People can experiment with custom ROMs when they have time, the purpose of my Guide is to get them up and running after bootloader unlock and root.
There are two additional potential considerations before flashing from stock open market us998 firmware to vs996. One is the potential loss of tethering/hotspot function. Verizon used to wrap a dongle around tethering functions to shake some extra change out of its subscriber's pockets. A need for native tether function was an important reason to switch to a non-stock rom.
The second is general weirdness or plain lack of service with Verizon phones on stock firmware when traveling internationally. Verizon says their phones work overseas, but my personal experience with a quark xt1254 and Turbo2 is that they do not. Even when fully paid there seems to be a hidden carrier/sim lock. Like tethering, flashing a non-stock rom gave service to the xt1254 in Europe and Asia.
Any Verizon users out there who can report on behavior specific to vs996 firware to help others in making an informed decision about its use?
Thanks in advance for comments.

I would also be interested in knowing if anyone traveled overseas with a VS996 and how it worked with other carriers' SIM cards.

VS996 Custom Roms

I have a VS996 that I Frankensteined and WTf'd. I flashed it back to stock VS996 from US998 (still rooted) afterward.
I've been rooting and flashing my android phones for about 10 years now, so this isn't new to me. But this phone is confusing as hell to me.
My question is: Are there any custom roms I can flash over VS996?
[ROM][Joan][UNOFFICIAL]ResurrectionRemix v6.1.0[8.1.0] says it works, but in some of the posts, people say they are running on a VS996 that was Frankensteined. Does that mean they have a VS996 but are now running US998 and the rom? Or they flashed to US998 and then back to VS996 and are now running the rom?
Or do I have to reflash US998 and go from there? Do I have to Re-Frankenstein?
Thanks.

All current era (last six months at least) "H930" AOSP/Lineage custom ROMs work with all V30/V30+/V30S variants -- except for T-Mobile H932. This includes VS996.
Think of "H930" label for AOSP/Lineage custom ROMs as meaning it's not for "H932", but includes ALL others. Conversely, do NOT flash anything labelled for "H932" on ANY other V30.

Related question I think, what is the advantage of 996 if I'm on Verizon network? Just bloatware?

Verizon users can answer that better. Sometimes stuff like texting, VoLTE, Wi-Fi calling can work better on carrier firmware. However I do not know if that's the case with Verizon. I think most Verizon users on US998 have workaround for all that, but I can't be certain

I've heard that you can't run Verizon's VOLTE on non-VS996 firmwares. Most custom ROMs also dont' support VZ-VOLTE because of this. I believe there's a thread with a reward for someone who figures it out, but bottom line is that it doesn't work today. For this reason, I have stayed with VS996. Honestly, it gives you everything you need... and you can easily freeze/disable whatever you don't want. NOTE, you do need the Verizon app to be installed and active for VOLTE to work, from what I've seen... but the rest can be frozen. Incidentally, it's better to freeze/disable than uninstall., because you can always restore it later if needed... too many people try to uninstall and then ask for the APK later to try to fix it...
I'm a Verizon user with a vs996. I have tried the different AOSP roms, and while they do ok, I have always had something not work exactly as it should, i.e., the texting, phone problems, or the quad dac, (depending on the rom) or some other just mostly little (not major) issues.
Last week, I finally tried the vs996 twrp rom, instead of the us998, that I normally run. After about a week, I decided that I did not like it quite as well as the us998 rom and so, yesterday I went back to us998. The vs996 didn't seem to work as smoothly as it should (I don't use some of the stuff people on here want that only Verizon has - - ie, wifi calling). At times I had to do double tap on things, just minor stuff. The other thing is, in order to use the Hotspot, you have to go thru Verizon, but, with the us998, I can use the included hot spot, if need be and not worry about Verizon.
So, I am very happy with the us998 rom. I would like to do more customization, but not a big deal if I don't. It runs the smoothest, for me, of all the roms I have tried.

I'm on Page Plus (Verizon service) and Volte doesn't really concern me. But I understand with roms not working correctly. I've flashed my fair share on my Motorolas. For the time being, I think I'm going to stick with stock since I'm still getting used to this phone. I just wish the recovery had rom slots like my old Droid Razr had so I could test out different roms without screwing things up, lol.
I do love this phone. Such a nice upgrade from the Droid Turbo. It was also nice to unlock it FOR FREE unlike the Turbo.
I did notice something with Titanium Backup (I used to use it on my Samsun Intercept and Razr). When I froze or uninstalled certain apps, they still remained in the App list in Settings as enabled or still installed. It caused havok when they'd try to run on their own (some Google apps). I had to unfreeze them and disable in Settings. Strange. All of the other bloatware still shows as installed, too.

I had the International version of the Moto Quark (sold under various names around the world: Droid Turbo/Moto Turbo/Moto Maxx) and yes the V30 is the phone I chose to upgrade from after 3 years. The V30/V30+ is the successor in spirit to that phone. It's the phone Motorola should have made if they had not lost their way with stupid mods.
For the record, I'm on Total Wireless (Verizon MVNO)... that's why I prefer to have VS996 for the wifi/volte calling.
I don't notice any lagging or slowdowns. I have disabled some of the VZ bloatware, so maybe that's what helped it. I was on US998 originally, but when I couldn't get wifi/volte working I knew I had to stick to this.
Keep in mind, I believe VZ will be going all volte in the near future? At which point, you may be forced to run a volte-capable ROM. Certainly nothing to worry about right now, but I thought that was happening in 2020 or something, so I figured I'd be ready from the start.

quick question:
I bought a frankestensteined US998 that was a LS998. It was bought running android 7.0, i updated it using LGUP to US99820e Android 8.0 Sept 2018 Security.
I have not rooted (checked it and it not rooted)
Bootloader, i didn't unlock it
I have dont nothing to the phone other than just update it from Android 7 to Android 8
I am running stock US998 and woud like to flash vs996 as i'm on total wireless (i have read about that and know how to do it, easy upgrade)
Can I return to US998 from vs996 just as easy, in case I want To go back to us998 what would i have to do?
thanks

Yes. You can flash VS996 KDZ via Frankenstein instructions. You can return to US998 also via Frankenstein instructions.
I had a question for all the rooted/unlocked VS996 users. Im currently running US998 because of the tethering function. I'd rather be on VS996 for the Volte features and just debloat. Has anyone figured out how to get around/disable the tether check Verizon has on this rom? Is there an easy way to get the tethering to work? I even tried the magisk tether module with no luck. Thanks for any suggestions!

MMS is only thing not working on V30 plus

I have an unlocked Sprint lgv30 Plus. It's an LS998. Switched it over to T-Mobile it has a T-Mobile SIM card in it everything works with the phone like LTE and SMS just not MMS. Tried a few times with the techs at T-Mobile and they can't seem to find the problem. Can anybody help with this problem? Thanks in advance
Is it bone-stock otherwise, or have you bootloader unlocked or rooted or rommed to get to LS998?

I don't understand bone stock but it was purchased from Sprint and nothing was done to it it's stock from Sprint. Nothing worked with the T-Mobile SIM until we got it unlocked from Sprint and we created the APN for T-Mobile. We tried all suggested APNs and still everything works but MMS.
Well, if it was purchased from Sprint, then they should be held responsible... it's their phone and ROM after all. TMo merged with Sprint, so it's their problem as well... not yours.
Without rooting the phone, there isn't a lot we can do here on XDA, because the manufacturers and carriers have locked you out of such things anyway. Once rooted, there are things we can try, but this should be your last recourse... it's their problem, make them fix it. If they can't then they should give you a replacement phone that works... after all, that's what you paid for.

You can always convert to US998 and see if that works to get MMS. There are many T-mobile customers on US998 firmware.
I spoke with T-Mobile and they said there's nothing they can do and they're only offering me $21 for the phone so I would like to do what I can to get it working such as routing and putting on us998 but I don't know how

That's surprising. How long ago did you buy this phone? I would certainly put up a much bigger stink with them, as they sold you a defective product. Of course, if it's been a while, then I misunderstood... your initial post implied it was a recent purchase.
Anyway, as for rooting it, use the WTF thread (as mentioned by ldeveraux above). The key is you must read it carefully and completely... multiple times... and on a PC NOT ON THE PHONE. The post is long, but the post is very clear and details ALL the paths you would need to take. You may not need to follow all of them, so you do the ones that apply to you, one by one. Print out the post, and have it handy to use a a checklist to go through the process.
If you're not sure, you can certainly ask on that thread. Keep in mind, MANY people have used this process without issue, so if you're missing something it's likely in the post, and you just need to be more careful reading it. In reality, you should have no questions, as everything is in there... so please make the effort to read it carefully, multiple times, and follow the instructions. It's not difficult... just very specific and precise.

You may not have to unlock bootloader and root just to get T-mobile MMS. I would first just try installing US998 firmware.
If that works, then later you can decide whether you wish the total control over your phone that root brings.
You would need to do some of this anyway for the "WTF" boootloader unlock and root method, but right now you don't have to do it all.
You just need to follow the Frankenstein instructions and first flash Nougat US998 (very old, but necessary), then do a Master Reset (explained in the instructions) to stop any bootlooping. Then you would install US998 firmware more recent like Oreo 20H US9998 (very stable, lot of fixes and improvement).
After that, put in your T-mobile SIM card and see if you get MMS. With US998 firmware you will now have these bands:
US998
CDMA: 800 MHz CDMA
2G GSM: 850/900/1800/1900 MHz
3G UMTS (HSPA):850/900/1900/2100 MHz
4G LTE Bands: 1/2/3/4/5/7/12(17)/13/20/25/66
As I said before, we have lots of T-mobile users on US998 firmware. So, surely they are getting MMS.
If that works to solve your problem and then you still wish to unlock bootloader and root, in the WTF Instructions you would have to do some of those same steps anyway (Nougat US998 and Master Reset), but would just TEMPORARILY use an earlier version of Oreo US998 (like 20a or 20b) before moving on to US998 20h.
Follow the "Frankenstein" instructions linked above. Read in a web browser, not an app. There's also several Trouble Shooting Steps at the bottom of that post.
This same issue happened to me, as well, except the problem was only with sending or receiving from apple devices. MMS and pictures worked fine to and from android devices. I purchased a V30+ from sprint back in 2017. Switched to T-Mo in Jan., 2021. My V30+ is stock. T-Mo's solution was to replace my V30+ with an LG Velvet as they could not figure this out and didn't want to be bothered. Was told it was my device and going from CDMA to GSM. I really like my V30+ and would love to find out how to get MMS working again so I can return this Velvet within the 14 days I have. Is it true if changing from LS998 to US998 that you lose VOLTE and WiFi Calling? These are important to me and would hate to loose those features but would also love to get the DTS audio. Any help is appreciated.

No, that's NOT true with T-Mobile. US998 supports T-Mobile VoLTE and Wi-Fi calling. Or at least they do with older SIM cards. Someone with newer SIM card says something may have changed. But that person had an MVNO SIM card, not official T-Mobile SIM card. Another MVNO said his SIM card still works just fine.
Follow the Frankenstein instructions, change to US998 Nougat, then Master Reset, then US998 Oreo 20h.
I tried looking at the Franken phone instructions and being a newbie I did not understand them so they're no use to me I've rooted phones in the past but I don't understand the instructions

Help, how do I enable VOLTE?

I am on red pocket service. I just received an email stating I do not have VOLTE enabled and may lose service. Supposedly, I should be able to enable VOLTE. I reached out to customer service in the past and they stated it is active on their side. Their website says I should be able to see it under settings -> mobile network; but I see not options for VOLTE. I have had **** service the past few months, with texts not being sent despite it showing bars or texts incoming taking a while; I wonder if this is related. Can anyone please help me?
I am on Android 8.0.0
Kernel 4.4.78
Version: US99820h
If it helps, VoLTE plus app says VOLTE is enabled. Do I need to be concerned? Is there any reason my service seems to run like crap? It's red pocket GSM-T. Had many people tell me calling me goes straight to voicemail, I get texts late, for confirmation texts I often have to restart the phone to get the texts to come through... Any fix to this? Should I switch to a different image and go onto a different set of towers/service?
Many V30 phones require the carrier's ROM to operate VOLTE. For example, when I was on Verizon, I had to have VS996 to get VOLTE to work. I also used it on Total Wireless (which is a VZ MVNO) for the same reason.
I'm guessing your GSM-T means you're on TMo, so you may need a TMo ROM to get VOLTE to work. US998 is a world-phone ROM, so it's not carrier specific, which may be why it doesn't work.
As for the general operation, you should be fine on US998 for all other functions... so if you're having issues then there may be something else going on.
You might also just need some updates - 20h is nougat level, which is ancient. You may need to move to Oreo... which worked great for me on my V30 in the past.

So, do you think I would need switch to a newer ROM, specifically for tmobile? I have been on us998 since buying it, always had some issues with texts coming in late and connectivity (although not as bad as when I had a S5 on Ting's t-mobile network). I had called and been told VOLTE is active with red pocket twice in the past, but despite always being on wifi I've still had people tell me I do not always come in clear when talking on the phone.
Can you point me to a newer ROM you used? I can try updating and messing with the phone later this month.
You can't use my ROM (VS996), as it was for Verizon. I doubt that will work for you. You need to find the proper on for your carrier (TMobile most likely) and see if that fixes the issues. All my ROMs I sourced from this website/forum, so you just need to search the V30 section here.
Note, when switching ROMs, you will need to wipe it so be prepared with backups for your data.

I had called and been told VOLTE is active with red pocket twice in the past, but despite always being on wifi I've still had people tell me I do not always come in clear when talking on the phone.
Can you point me to a newer ROM you used? I can try updating and messing with the phone later this month.

Just be careful NOT to flash H932 ROM on your device, it will brick your phone.
You could try updating to us998 Pie ROM and see if it helps.

Do you have a us998 pie rom you recommend for me to try?

I saw chazzmatt mention in another thread that when t mobile and sprint merged, VoLTE/VoWiFi calling on US998 firmware phones may have been lost. He suggested that changing to verizon version is a way to fix this. Is this something I may have to do? And is there a guide on how to do it? I only see switching to us998.
And this would this be the rom to flash to for android 9?

@ChazzMatt is the resident expert, so you can certainly take his advice. I saw that post as well.
Converting to VS996 just means you will use LGUP to flash that ROM over your current one. The end of the WTF post/thread talks about this process as well (be sure to read that post on a computer, as phones often cut-off the bottom).
Note that this will erase your data, so backup/etc as necessary before doing that. My recommendation is to use the last Oreo version of the ROM, as Pie on VS996 had issues last time I had heard... that's the last ROM I used before switching to my other phone.

And in doing so, they still need an already-activated Verizon SIM card or Verizon MVNO SIM card. Verizon won't activate a SIM card with a phone that doesn't have native Verizon IMEI. But you can stick in an already activated SIM card into a v30 with VS996 firmware and it's fine. So whoever does this needs to also have an old Verizon phone for that purpose. Buy some cracked screen Verizon phone off eBay, activate Verizon or Verizon MVNO SIM card, THEN put that SIM card into Frankenstein'ed phone flashed with VS9996 (Verizon) firmware.

Are phone numbers attached to the sim? So I would have to: obtain verizon sim card, transfer my phone # while activating a plan on it using another phone, then place it into my current phone after flashing it into VS9996 and upgrading it to 9.0?
Yes, the phone number is attached to the SIM card.
Yes, your steps are correct - activate SIM on some other phone, then put it into the VS996.

Hmmm, perhaps before I spend money to switch to verizon I should try upgrading from US99820h to US99830b using that thread I posted above? Maybe that will fix things for me. I thought I had fixed something when I updated my redpocket APN point, but I still get random loss of service where I live and work at (despite constant wifi). According to redpocket customer service, being locked into 240 MNC sim card does not change anything compared to 280 MNC.
Perusing the us99830b thread, I saw if I have TWRP installed then I must use johnfawk's image to flash. I cannot "upgrade" and keep all my data using the firmware off LG's website with LGUP. Am I understanding that part correctly? And the TWRP image for me to download is this link? Mirror Link
First, my recommendation is to stay at Oreo (20-series) ROMs. Last I recall, the V30 Pie rom had issues that were never fixed.
Secondly, yes, I don't believe you can upgrade the ROM... you will need to flash the full ROM which would erase things. That being said, since you're already converting between ROMs you will need to wipe the phone anyway, so do all the updates/upgrade BEFORE you install anything else on your phone. And, of course, backup everything you need before doing that...

You mentioned before that 20h is nougat level, but my android version says 8.0.0, isn't that oreo already?
Looking at this site: https://lg-firmwares.com/lg-us998-firmwares/
I am already at the latest Oreo software. So, several questions:
1. I could back up all my stuff and risk missing something, but I can also just create a current TWRP image and go back to where I am presently in terms of all my stuff?
2. Should I be trying a https://lg-firmwares.com/lg-vs996-firmwares/ VS99620k version? When I reboot my phone it says it is a LG V30+ThinQ and I vaguely remember the box it came with said LS998 crossed off, with it booting as a US998 phone.
3. I have an old CDMA Galaxy S3 (best phone I've had). Assuming I am able to boot it up, can I buy a verizon MVNO sim card (let's say off of TING), switch my phone # to that and pop it in the S3? Or can I bum someone else' verizon phone and do this, then give the phone back instantly?
4. If a friend has an old verizon sim card, can I use that to utilize either red pocket or ting services?
5. Then, flash this US99820h to VS99620k, swap the sim card out of the S3 into the newly flashed V30?
6. Assuming I do all this and I still see no menu for VOLTE, assuming I still have the same issues of service dropping constantly, any suggestions for moving to a new phone, or what to use to find a new phone? Many new phones seem to have lots of stuff I do not care for (fancy cameras...) and no 3.5mm jack; but I really crave a phone that is functional.
Sorry for lots of questions. But each day this phone is pissing me off more and more and reminding me to do something about it - been busy and have stuff I do not want to risk losing.
I didn't say 20-series was nougat... I said it was Oreo?
1) TWRP will backup everything, so you could use this as a way to "keep safe" what you have now, and maybe you can break into the ZIP and extract things here and there as needed, but I don't think you can use this as a way to restore just your programs/data... it's a whole-image that you need to restore, which includes the OS and such. But if you're already on Oreo, I don't think you need to do any of that?
2) Yes, you can apply VS99620k. I believe that's what I had on my V30 before I left it. I wouldn't pay much attention to the splash screens on bootup... they change between versions but don't really mean/do anything from what I could see. My phone started as US998 (without the "ThinQ" branding) and I believe it showed the ThinQ branding when I was on VS996.
3) Yes, you'll need an activated SIM on VZ to transfer. Yes this is one way to do it. I did something similar with my Droid Turbo. VZ won't activate anything unless the IMEI matches THEIR phone, so this is one way to get that to happen. The trick, today, is that VZ may not activate the old phone because it's not VOLTE capable, so they'll say it's not supported, so that's a risk you should be aware of. For that matter, a newer SIM also may not work on the older phone... I don't know if that's a thing or not.
4) I don't know if MVNOs will let you use VZ SIM cards. Technically, they should be able to, but my guess is they will require their "own" SIM. You'd have to ask the MVNO.
I moved to the Galaxy S10+, which is a similar size phone, has a headphone jack, and is older so it's lower cost (I think I paid $300 about a year or two ago). A few other V30 faithfuls have followed this path as well. I think ChazzMatt went to a Note because that's what ATT gave him to help him transition to a VOLTE-capable phone. I believe he's still using his V30 though.
Newer Galaxy phones lost the headphone jack. I would recommend getting yourself ready for this eventuality... it may mean just getting a dongle, which isn't convenient, or getting bluetooth adapters... but my point is that it's going away whether you like it or not, so start preparing now.
EDIT: I forgot to mention, the S10 is not rootable (at least with Snapdragon). Exynos can be rooted, but I don't know how usable those are in the USA. That's another thing you may need to get used to - not being able to root/ROM. IMO, it's not necessary anymore, and I have given up on it on my phones... and I haven't missed it AT ALL. But I know some have gotten into heated arguments with me over that... one I recall was particularly nonsensical, but whatever. If I could root, I would do that... but I don't see it as a requirement anymore.

As @schwinn8 recommends staying on Oreo, I also concur.
1) If you have TWRP, just flash the Verizon last Oreo by John Fawkes. See link below.
LG V30 Verizon VS996-20k ROM
Working downlink mirror: VS996 20K Verizon TWRP-flashable ZIP
2) If you don't have TWRP installed -- for people who are not bootloader unlocked -- then you would flash full stock ROM VS996 20K "KDZ" file from US998. See top post in this thread. (For those who are still bootloader locked, the stock Verizon ROMs and US998 ROMs are the only ones for North America variants which are safely fully cross flashable without first having to go through the "Frankentein" conversion "Nougat" stage.)
As for spending money on Verizon to get VOLTE, there are several Verizon MVNOs that are less expensive than Verizon proper and will still do the trick. Both Visible and Total Wireless are even owned by Verizon, like Cricket is owned by AT&T.
RedPocket also offers Verizon-network SIM cards. They are also a Verizon MVNO. Which carrier service are you using with your RedPocket? They offer choice of AT&T (most common), T-Mobile and Verizon. I searched your posts in this thread and you don't say which you have -- so I assume the AT&T-linked SIM card? If you flash the last Oreo TWRP-flashable zip for Verizon, and you want to keep RedPocket, just have them ship you the Verizon-linked SIM card. You should then have VoLTE.
NOTE: You would still need to use an old Verizon phone to activate that SIM card, but then you could put it into your "VS996". I'm only suggesting a way to not have to actually switch to Verizon, you can still use Redpocket but have them send you a Verizon linked SIM once you are on Verizon firmware.

Got it, if flashing is all I have to do, this will be simple.
I was not clear, I did mean verizon MVNOs, meant more verizon in broader sense: CDMA. I am currently on red pocket T mobile. I was previously on Ting. Had similar issues on both with randomly losing service. It was bearable, but since 3G shutdown timeframe, this became a larger and more frequent issue. Currently, if I turn on data, I get Edge service (I read this is 2g?), otherwise when I am having a texting conversation, I am regularly losing service completely and do not have strong service in places where other Tmobile users have regular service.
On another note, I am looking to swap from red pocket; I spoke to customer service about call records, was told several times they would be sent to me, never received anything. Red pocket prices are hard to beat though.
I impulse bought a pixel 7 unlocked too (there were some incentives that were hard to resist). So, I will probably swap to that phone while holding onto this one and tinkering to see if it was a phone issue, US998 issue, SIM issue, service issue... then give the phone to family in a year or so.

Any custom ROMs that support VoLTE?

I'm running rooted stock 30b (US998), and it's been running solid for years until lately. Now it seems it's starting to lag and slow down to the point of near unusability.
Want to try using a custom ROM to see if that will alleviate the issue, but due to my carrier (MVNO of T-Mo), I need VoLTE. Normally LineageOS is my go-to, but the 19.1 build doesn't support VoLTE and it says it probably never will.
I see other ROMs as well, but if they're all AOSP/LineageOS based, then can I safely assume they won't support VoLTE either? Or are there any custom ROMs out there for the V30 that DO support VoLTE?
VoWiFi would also be nice
Thanks
As far as I've seen, no custom ROM supports VOLTE on this phone. Maybe other phones have it, but not this one. There was a "reward" post for someone finding a way to get it working, but it never happened.
I've heard issues with Pie ROMs on this phone, as the released version wasn't done very well. I might suggest going back to US998 Oreo as this may resolve the issues for you.

Not for custom ROMs. In fact that's why we created this other thread that by 2022 all U.S. owners of V30 would have to go back to stock ROM -- due to 3G bands (CDMA & HSPA going away and VoLTE being necessary for phone calls with carrier numbers. You can ROOT the stock ROM to still modify stuff, but only stock ROM allows VoLTE.
All U.S. V30/V3O+/V30S will need stock firmware, not LOS-based custom ROMs. When?​
All U.S. V30/V3O+/V30S will need stock firmware, not LOS-based custom ROMs. When?
3G CDMA and HSPA is going away. U.S. users will NEED VoLTE and/or Wi-Fi calling for carrier phone calls. V30 LOS-based ROMs do not have that and will never have that.

I started that thread back in mid-2020 to warn people in plenty of time. AT&T, Verizon and T-Mobile (which includes former Sprint) delayed their timelines a little but still the admonition is true. Users in other countries that still have 3G in addition to LTE can use custom ROMs.
The caveat to that is unless you are using a VoIP phone number (which uses data) -- like Google Voice -- and don't need carrier based phone calls. But most people only use carrier calls.
