AT&T VoLTE with custom ROM possible? - Samsung Galaxy S9 Questions & Answers

AT&T sent me a Samsung Galaxy S9+ because my Xiaomi Mi 8 apparently won't to VoLTE on their network -_-
If I put a custom ROM on it will I still be able to get VoLTE with AT&T?
Should I first activate it and then root it and backup EFS in case I need to copy that over to the custom ROM or should that not be needed?
Thanks in advance.

Any help is very much appreciated.

AT&T NOTE 3's Bootloader is LOCKED so for now there is No CUSTOM ROM OR CUSTOM RECOVERY. So NO Tmobile Rom will not work Until somebody find a way to unlock At&t note3's BOOTLOADER.

Thank you for the information. I'll just wait til someone unlocks the bootloader.

issue with SM-N910P

I have a newly acquired Note 4 running Android 4.4.4 acquired in Thailand. The sticker under the battery identifies it as an SM-N910F, as does the ROM.
However, both Samsung Kies and the bootloader identifies it as a SM-N910P, the Sprint version of the Note 4. If I flash a stock Sprint 5.1.1 ROM the phone works fine. But of course, locked to the Sprint network, so useless to me in Thailand.
Could someone advise me on a 5.1.1 ROM to use that is not network locked to Sprint?
Thanks

Google sm n910f rom. Take your pick.

Globally sim unlocked n910p, looking for a good unbloated/unbranded/fast minimal ROM.

I'd like to first point out that I use T-Mobile as my carrier.
I had a Sprint S5 unlocked with the same method (Idoneapps global sim unlock) and I was able to flash my gn900p with gn900f ROMS, and it worked great. However haven't attempted to flash my Sprint note 4 n910p with a n910f rom - I read it would brick my Note 4 so havent tried. I did however flash my sprint note 4 with ROM][AOSP][UNOFFICIAL][RESURRECTION REMIX v5.6.5] TRLTESPR MM 6.0.1 [03/23/16] and I couldn' get a network signal and was unable to get into the hidden menu no matter what I tried. Is it possible to flash my Note 4 n910p with a n910f or even a n910t ROM (since I use tmobile)? Or if not possible, how would I get RESURRECTION REMIX v5.6.5 to work with my tmobile sim?
As it stands now I have my sprint note 4 running the latest OBAR ROM, and honestly every thing works pretty good with my tmobile sim. Id just prefer a more minimal Rom, I dont care about s-pen or heartbeat monitor etc., I never ever use that stuff.
Thanks for any input
CM 13 with Slim G-Apps. Daily driver, zero issues. Make sure you use the recommended baseband.
How did you get you n910p globally unlocked?

unlocking att version and using tmobile rom?

Hi All!
I really want the note 5 rom. I have the att note 3. Curious, if I unlock my att to be able to be used on tmobile, will I be able to use the note 5 rom made for the tmobile note 3?
TIA
If the phone has a lockd bootloader, you cannot install cwm or twrp. You could use safestrap to install a custom rom but the custom rom cannot be based on cm or aosp. A note 5 ported for use on a note 3 may not work on the att version of the note 3.
