rooted? unlocked? rom or stock verizon?
also how are you verifying you have t-mobile "signal"? call or text yourself.
Our rooted DI2 was unlocked via VZW before going on our Bermuda cruise last month, worked great for voice & incoming SMS roaming on prepaid carriers - black one running SkyRaider and red w. Condemned's Sabotage Sense, also switched to my China Mobile 3G Rom and had a very good signal - using the island's DigiCel partner's signal tower ... same on the ship as we switched off our CDMA services. I didn't change the APN settings for SMS/MMS and had issues not being able to send outgoing msg, something I didn't planned on doing ...The installed ROM was able to pickup and lock on a GSM signal fairly quickly and showed service on our devices.
Back in the States, if I switch to over to GSM only, we will pickup a very good signal for T-Mobile, AT&T; or, China Mobile 's Sim via AT&T or T-Mobile, good enough for voice calls & SMS. It depends, in part, on your GSM carrier's tower and partner carrier lists.
after updating my phone lost 3G corvertura and receive only LTE but I can not make calls or receive them but if I get sms and live in Dominican Republic
I've about had it with this phone internationally unlocked HTC 10 here originally had Oreo on it I downgraded back to nougat properly with the 2.51 latest firmware and now Sim is working on nougat but any AOSP ROM I use voice over LTE never works. I don't absolutely need voice over LTE to work but my phone does not always switch the connection to 4G to receive incoming calls either sometimes it would just stay on LTE and then the caller will be pushed to voicemail immediately. I can make calls from my phone fine but receiving has been a huge problem. I even tried the leedroid nougat ROM and it is doing the same thing as I thought it was an AOSP problem but that can't be the case as it possibly something with my firmware? I just want this headache to go away and receive my calls properly again! Any help will be greatly appreciated
Carrier is tmobile
So I've discovered that volte does not work with AOSP ROMs but it seems when I get a call the LTE does not go down to 4G to let the call be received is there anything I can do

Question about the impending doom of custom roms. I'm with T-Mobile and don't want to switch. So are texts included in this as well, or are only voice calls affected?

You are talking about this:
All U.S. V30/V3O+/V30S will need stock firmware, not LOS-based custom ROMs. When?
The first post is the most relevant. By page 3 the discussion had digressed into other areas.
At first, I thought only voice calls should be affected. (But... don't you need voice calls? Or do you have something like Google Voice? I have Google Voice but in the U.S. I still piggyback on my carrier's assigned phone number.)
(backstory, skip over this if you already know it)
4G LTE started out as "data only". Initially carriers had you temporarily dropping down to 3G (HSPA or CDMA) for voice calls until VoLTE (Voice Over LTE) was perfected.
But for V30 LOS custom ROMs -- which don't have VoLTE -- users still needed this temporary 3G access during phone calls. After the phone call is over, then you jump back to LTE (data only).
Now that 5G is being rolled out, U.S. carriers are killing off 3G to use those resources for 5G. AT&T is keeping 3G HSPA until February 2021, but initially it was reported Verizon and T-Mobile (Sprint) -- and their MVNOs -- are ending 3G in the next couple months. Verizon by January 1, 2020 and T-mobile allegedly in "January 2020" but they have set a specific day of the month that I've seen.
HOWEVER. HOWEVER...
T-Mobile may not be abruptly ending 3G HSPA in January 2021.
Instead T-Mobile says if your phone is not VoLTE capable by sometime in January 2021 it will be shut out of their network. This is not saying they are shutting down 3G HSPA in January 2021 -- just forcing all phones on T-mobile network to be VoLTE capable for WHEN they do shut down.
Hmmmm...
This potentially means you could still use custom ROMs a while longer if you somehow pass their VoLTE capable test? Because 3G HSPA may still be available for a while longer.
On the other hand if you do NOT pass their test, you can't use their network for texting either!

How to find out if your T-Mobile phone has VoLTE support
T-Mobile will shut out all incompatible devices next year (2021).
Check the Settings app
If your phone is already activated on T-Mobile, you can check in your phone's settings if VoLTE is being used. Open the Settings app on your phone and go to the 'About phone' menu, then tap on 'SIM Status'. If you can't find it, try pressing the search button in the app and typing SIM.
Once you find the SIM Status option, tap it, and a popup should appear. If the voice network type is listed as LTE, you're good to go.
If your Settings app doesn't have that menu for whatever reason, try dialing *#*#4636#*#* in your Phone app. This will take you to a hidden diagnostics menu. Select 'Phone information,' then check if LTE is listed under Voice Network Type.
Ok, I had read some of this before, but not all. My phone passes those VoLTE capable tests. So does that mean that my phone is capable, but still not using VoLTE because it's on a custom rom? But that since it's capable, I'll still be able to use 3g network until 2021? And that once I lose voice, I lose texting as well?
If your carrier completely switches to 4G network then you can't use even text messages without Volte
Though using Google messages with RCS may allow you to get and send text messages with internet connectivity.

My best guess, but I'm not T-Mobile:
If your phone passes those tests then it probably won't be locked out of the T-Mobile network in January 2021. If so, then you will still be able to use LOS custom ROM for voice calls, for as long as T-Mobile keeps 3G towers running.
When they do shut off 3G -- may happen gradually, not all at once -- you will not be able to make phone calls on custom ROM without VoLTE, but should still be able to text.
Texts are data, and data-only LTE signal should still allow texting.
LG G8 won't call or receive calls after the update to G820UM40a...was working before...not after. WiFi calling is grayed out. Calls terminate within a couple of seconds. I have internet & other than the calling issue, the phone works very well. Does anyone have ideas on what to do? I don't have a menu listing for Network changes..what would be a good way to get into the GSM settings?
Or does anyone have the last ATT Android 10 or 11 rom?
