I'm not sure if this is supported, I can't seem to get much help from AT&T, but I purchased an unlocked Note 10+ from Samsung. I do not have WiFi Calling which is a crucial feature since my office has terrible reception and I use the phone for work.

Is this something I should be able to get working with help from my carrier or is this ROM/build specific? Any help would be appreciated, thanks!

Along with one or two pros, I found this to be one of the cons in using an unlocked phone with Verizon a couple of years ago, along with no notifications. I spent countless hours over several days on the phone with Samsung and Verizon before finding out this was a known (by Samsung) issue. I returned mine and got the Verizon branded one. Things may have changed since then, but it cured me of the unlocked version, especially since contracts have fallen by the wayside. If they can't resolve the WiFi calling, Samsung should allow you to return it. I hope someone else has a solution for you.

Glad I read first, I'm going through the same thing right now. Just downloaded the firmware from Sammobile about to try and see.

I am in the same boat. Just out of curiosity what does the service provider SW ver. look like? Mine shows ATT/ATT/XAA

Still no wifi calling or carrier specific options...it's kind of strange that these phones provision the features when you put a sim card in.

I called both At&t and Samsung who were equally less than helpful.

I am looking back to some of the S8+ forums about CSC swapping because I feel like that might be a starting place...

You downloaded N975U1 unlocked rom, it was still rom for unlocked note 10 not AT&T or variant note 10. If you want full AT&T features like wifi calling, video calling..you should download and odin this firmware N975USQU1ASH4 which is AT&T Variant N975U. I am still on unlocked Galaxy note 9 N960U1 and I odin Verizon note 9 SM-N960U on my unlocked Galaxy note 9. The ROM works with every carrier anyway.

Okay , I got my WIFI calling . This is the correct one to download and flash......... DO NOT Download the one that says AT&T it's going to just flash the same N975U1. Good luck

I'm thinking about doing this. Will flashing the at&t firmware wipe the phone? Articles I've read says it doesn't. Is that correct?

Also can someone confirm the correct at&t firmware for the Note 10? Also use the USA(USC) version?

What about for the regular Note 10? Is it N970USQU1ASH4 for the unlocked AT&T version?
