Unlocked able to use WiFi calling on T-Mobile or able to flash T-mobile firmware to Unlocked?

[anon(10509503)]

I currently have the Note10+ and I flashed the latest T-mobile firmware via Odin to get everything working properly including WiFi calling on T-Mobile. Do we know if we will be able to do the same with an unlocked Note20 Ultra? I live in the sticks and WiFi calling is my only option for making calls so it's pretty important to me.

I have a N10+ unlocked on T-Mobile. Wifi calling works no flash, just put my sim card in and it all worked.

Yes no problem

That's good to know for future use. I was having signal issues on straight unlocked. For whatever reason my signal bars were grayed out so I flashed the T-Mobile firmware and it started working.

Do you have any issues with RCS messaging on the Samsung messages app? Like with advanced chat features?

I'm not sure at the moment, most people I text have iPhone or don't have RCS enabled on their androids.
