No wifi calling option on S10E (SM-G970U1)
Model: SM-G970U1
Andriod 10: one UI: 2.1
G970U1UEU4DTF3
Using MVNO ATT SIM.
No wifi calling option to turn off/on in the dialer app, no VoLTE. MVNO said I am confirmed to enable both options though.
Is this an ATT sim restriction for unlocked/non ATT devices? I did plug in my wife's att sim card and was able to get LTE+ but no wifi-calling. This isn't a branded ATT S10E.

I have an Unlocked S10e (U1) and the only way that I could get those AT&T features was to flash the "U" firmware AND the AT&T User Data file that has all of that crappy bloatware. I also used my old AT&T SIM card that had been in AT&T's system for years on previous phones. I had to do the same thing with my Note10+ too.
Another S10e that I have is still on U1 firmware & I just popped in a T-Mo SIM with no problems. Wifi calling etc. Work except I needed to download a visual voicemail app. Otherwise working great.
AT&T makes it so difficult!
It was a must for me because I have poor AT&T service where I live & need wifi calling.

Thank you, that is what I expected from ATT. I will switch to verizon MVNO. I don't want to have an unlocked phone, only to be forced to install carrier bloat.

I just got a Sprint phone and I am in the process of unlocking it. Once I unlock it, should I flash the Sprint S7 with the T-mobile S7 firmware since T-mobile is my provider? I know I won't get wifi calling and VOLTE, but I figured the preconfigured settings on T-mobile APN etc will make it easier for me to use the Sprint phone with less issues? The other option was flashing the International unlocked firmware.
What are your guys' thoughts?
Hello everyone,
I bought a samsung s10e that I suspect is the AT&T version G970UZKAATT. This phone is supposed to come sim unlocked.
- Does that mean that when I insert a TMob sim card, will it reboot like the S9 and the TMobile logo will show up, then
the phone will work just like a regular TMob version G970UZKATMB?
- Will it have wifi-calling for TMob?
- Will it support all TMob LTE and HSPA frequencies e.g. band 71?
- Do all versions of the G970U support the same frequencies once unlocked just as these websites suggest?

Hardwares all the same. No, it wont boot with a Tmob logo. If you want it to act like a Tmob G970 flash the Tmob firmware.
I was just testing a S10e that has G970U1 as model (probably flashed) on the back says G970U.... I inserted an Ultra Mobile SIM card (TMob mvno) and it seems that the wifi calling works on the unlocked ROM .... So no need to flash TMob version, I believe.
Can anyone confirm wifi calling works on the factory unlocked version?
I have the g970u1 factory unlocked with u1 firmware. It has tmobile wifi calling. The only things missing are tmobile video calling and that rcs messaging I think. But, I flashed the tmobile u firmware a couple months back and the phone booted up like a tmobile branded one with the jingle and stuff. I didn't need those so I reflashed the u1

Thank you so much for confirming. I've just got my g970u1 factory unlocked and wifi calling with Ultra (TMob mvno) seems to work too. I tested using airplane mode enabling just wifi and I can still make calls
Will an unlocked TMobile version of this phone work on an existing Verizon line without having to ask verizon to white list the imei or add cdma less etc?

I have Unlocked T-mobile A71 5G, It works on Verizon network like 4G LTE (just swap the SIM card even I have 5G Sim card from Verizon) but NO 5G because they are using different 5G Band.
I have the same question, but on cricket wireless, I can't get the phone to login to their network
It works just fine on any GSM/LTE network. I have not checked this personally for this device, but depending on the variant you have, you may be missing some LTE or 5G bands specific Verizon. You may not get full performance. That must be verified though.
I am thinking of purchasing a Samsung Note 20. If a phone is unlocked I assume it would work on T-Mobile. My question is if I purchase an ATT variant, I know the phone would work with a T-mobile sim, but will VOLTE (wireless calling) work if it an ATT branded phone and wether there's an issues with updates.
Thank you

Basically it should work.
According to the following thread, there might be some issues using 5g though:

My phone is an unlocked AT&T phone. It has AT&T bloatware. The serial number indicates it is an AT&T phone. The service provider software version is ATT. I bought the phone so I could use the wi-fi calling feature which is nowhere to be found. Put the AT&T SIM in my son's phone and he has wi-fi calling. AT&T's website gives the latest firmware as G970USQS5GUF1. My phone was just updated OTA to G970USQS6GUI1 which happens to be the T-mobile firmware. I put a T-mobile SIM card in the phone and I now have wi-fi calling. T-Mobile coverage is basically non-existent in rural Appalachia so I don't want to switch carriers. I have read numerous posts that say the basic firmware is the same for all carriers. So, my question is which files do I need to flash to get wi-fi calling working on my phone? Also, I can't really go back to BL 5 can I? I am totally new to this although I have flashed a Moto before.
