how do I update android OS after unlocking? - AT&T Samsung Galaxy S6

Right now at&t supplies OTA updates, but after I unlock and put in a European sim card, where do I get my updates?
model: g920a
version: 5.1.1
security patch level: 2016-02-01

Sorry you will not receive OTAs from AT&T to update your phone.

AT&T unlocked Samsung S6 Edge does not get Security patches, what to do?

My Samsung S6 Edge was unlocked by AT&T and subsequently updated to Marshmallow 6.0.1.
Unfortunately, since I no longer receive OTA updates from AT&T, I also no longer receive
Security Patches either. Is there a way to access the Security patches so I can keep the phone
up to date?

Note 9 (SM-N960U) on ATT - Never received OTA updates

Currently running Baseband Version N960USQU1CSC1, Android Security Patch level: March 1, 2019.
I have never received an OTA update since buying my phone in Aug 2018. For the Android Pie update and all updates since, I have been performing them via ODIN.
Neither AT&T not Samsung have been able to troubleshoot this issue. Appreciate any help on how I can setup my phone to receive OTA updates.
Thanks!

The new firmware is in another post. Just Odin and you'll be current.
I have unlocked on AT&T , and just got the April update this morning, all OTA. Never had to Odin the updates , but definitely not as quick as the carrier branded models. I have only added the APN names when I got the phone(preorder so August 2018) and that's the only setting I changed.
Didnt think flashing instead of waiting for OTA would cause any troubles, but Samsung is sneaky sometimes. Have you thought that maybe you flashed the incorrect files, maybe carrier vs unlocked? Also, factory wipe and reset ? I know the pie update did some screwy things for me and it seemed better after a wipe .

[Q] Questions about updating to U1

Right now I am on N960U ATT and only have the Feb 2019 security update even though ATT is listed as April 2019 being the latest. I have checked a few firmware sites and there are only Oreo firmwares for the ATT N960U but if I look for ATT on N960U1 there is the lastest firmware (April 2019). Can I update to that using ODIN? And if I do will I lose HDVoice/VoLTE/etc + carrier aggression? And if I do will I still get OTAs?

OTA update for N960USQU1CSA7 baseband version?

I'm trying to look for the OTA update to update my Note9, which is running on N960USQU1CSA7 baseband version. I can't seem to find it anywhere though, the baseband version isn't listed on firmware science either. Any help would be appreciated
Baseband version: N960USQU1CSA7
Security patch level: January 1st 2019
Build number: PPR1.180610.011.N960USQU1CSA7
While I persumably have your attention, might as well ask this
Using Odin can I flash USC (USA Unbranded) region firmware to my device? The device is an AT&T carrier version so it's region is ATT.
If I was to update, either by OTA or by flashing with Odin, how do I avoid losing any data on the phone? I have backed up my important files but wish to avoid the hassle of setting up my device again.
