Does s21 ultra unlocked have wifi calling with att? I got the tmobile version if I flash unlocked software would I get wifi calling option with att?
Also if you flash carrier specific firmware do you get their updates as well or based on your sim?

Someone just posted that they bought the unlocked US version and wifi calling is working for them with ATT without flashing any firmware. Hopefully it is the case.

Unlocked on AT&T wifi calling works fine, HDVoice (AT&T version of VoLTE) works also.
Can't help you with the flashing questions.
Hello, I return to the topic, the security patch for the month of March for the SM-G998U1 has arrived and Wi-Fi calls have stopped working, someone else has stopped working, I am on Android 13

So I currently have an att sims card in my device. And I'm noticing a ' T-Mobile update service Update postoned' message. Is it safe to take the update even though I'm using att with this device?
anyone's input how this may affect an at&t user appreciated.

I don't think it should be any problem to update the phone with the att SIM on... at least in theory. I unlocked my T-Mobile Note 4 and it's working flawlessly on att at full LTE speeds, minus Wi-Fi calling and VoLTE of course, but I don't really care for those features on AT&T.

I'm going to root/custom recovery later anyways so I'd probably over write it with a custom rom. Probably doesnt pay to update.

It will update your baseband (modem) and a few other things that are inaccessible to the user, so yes, update it. In fact, the update does update the modem to version NJ7 (you're probably on NIH).

I am on N910TUVU1ANIH, So updating the baseband is needed to be compatible with custom roms? I'm just worried about bonking my signal since its not a tmobile sims.

I unlocked, upgraded to ANJ7 from that version, did this: http://forum.xda-developers.com/not...sy-steps-stock-odin-n910tuvu1anih-cf-t2903733
then this:
http://forum.xda-developers.com/not...v1-4-4-4-tw-anj7-extremely-t2916463?nocache=1
with no problems using the t mobile one with an att sim, have been connected to 4G LTE all day.

I'm on the latest update with latest modem and I have absolutely great reception on at&t with my T-Mobile Note 4. Better than my Nexus 5 for sure.
Guys, I have a question for anyone that's SIM unlocked their 920T's. At the moment, my 920T is running xtresolite 2.2. It's based off a 920F firmware. As you know, this is an International version. To further complicate things, I needed to SIM unlock my phone so right now I'm using the MetroPCS COF9 baseband. Every time I switch back to a T-Mobile based ROM, my SIM unlock gets pulled and the phone is relocked back to T-Mobile (has been confirmed in multiple posts on XDA). I'd just stay with xtresolite 2.2 but I have no wifi calling or volte. I'm trying to find a rom for this phone that supports a different carrier sim as well as volte/wifi calling when I switch back to my T-Mobile sim. Is this possible?
All the ROM's I find for the 920T are either locked down T-Mobile ROM's under that development section and the general development section is mostly compatible International variants - but lacking WiFi calling or VoLTE. I'm beginning to think these two things just can't work together on the same ROM.
Thanks so much in advanced for a reply!

If you want unlock while on T-Mobile rom. See here: http://forum.xda-developers.com/tmobile-galaxy-s6-edge/general/sim-unlock-t3186826/post62512066
Other than that, not sure about WIFI Calling etc
Hello everyone! How are you all today? I hope this day finds you well! My question is, if I downgrade my at&t s6 active to 5.0.2 and root it, then will I be able to flash a rom to it that supports the t-mobile/metropcs VOLTE and wifi-calling? I use metropcs, and I got a good deal on this unlocked phone, but I didn't know the at&t Volte works differently than metropcs, and as a result my service has worsened.
Well, as the title says, when I enter settings and then system updates, it starts to search for an update, but the after like 20 secs it stops and says "We have troubles authenticating your device, please try again later"
My note 9 is model SM-N960U and it's original carrier, is Verizon. I'm in Mexico tough, but it is unlocked, maybe that has to do with the problem? Any help appreciated.
I have a unlocked 960U1 with Verizon and am in the US. No update available. Maybe it is rolling out to Mexican customers only?

Yeah that's what I thought, but if I do, I'll lose things like VoLTE or any software features?

You don't lose VoLTE on unlocked firmware unless you have ATT. Think OP said he was on Verizon. It works fine. Wi-Fi Calling would be lost (which is weird since they got that working on unlocked with S9 series, too).
Not sure what carrier he is on he said it was a Verizon phone that's unlocked but he was in Mexico so he might be able to get it I am on att and didn't know other carriers let you have volte thanks for the correction

Oh maybe that's where I should've started. Sorry.
To be clear, the phone is from Verizon. The active CSC is VZW, as I mentioned, the phone is unlocked and I use it in Mexico with TELCEL carrier, i DON'T have VoLTE nor wifi calling (TELCEL only has VoLTE) the model is N960U. Do you think there is a way to get VoLTE and/or flash an 960U1 software even though mine is 960U?
Thanks for your responses

you can flash the u1 firmware just be sure to back up your data because the flash will erase your phone
Hey, I have successfully flashed a Sprint LG V40 v405ua to US firmware 20g but VoLTE is not working. I am on Tmobile network and every time I make a phone call it switches from LTE to H. I heard Tmobile will be moving all phone calls to VoLTE in the middle of 2022. How can I enable VoLTE? Am I missing something? Thanks!

if you have access to the OP section, try to change it in cust.prop ro.vendor.lge.build.target_operator = OPEN to TMO

I'd suggest looking at the apn settings. That should be working (volte) without any system modifications.
I checked the APN settings and they are all correct. I am using US firmware version 20g, should I try using an earlier one like 20f? What versions are wokring for you? thanks

I don't have a v40 anymore but remember any version I tried of us open cross flashed to my at&t would work no problem. I remember my carrier mint mobile required you to select 'vowifi' in the account to get that to work. But volte always worked.
you might want to consider joining the v40 tele grp see if they can further assist. Maybe also consider calling t-mo, re your account may not be provisioned for volte? Not sure that's even possible but why not check anyway?
If it is like AT&T does whitelisting, ROM does not matter, but IMEI.
