Samsung Galaxy S22 Ultra Unlocked

I'm currently using an unlocked Samsung Galaxy Note 10+ that is working fine on the xfinity mobile network. It was a bit of a pain because I had to buy a cheap $90 Motorola phone from Xfinity and Sim-swap but it's been working fine since.

I tried to pre-order the Samsung Galaxy S22 Ultra through Xfinity Mobile but it was saying it wouldn't ship until April so I wasn't having that. I canceled the order and pre-ordered through Samsung which will ship this month. After I placed my order though, I read up on some forums that people were having all sorts of issues with the factory unlocked Galaxy S21 Ultra and I'm worried I/we might run into those issues with this new one.

I obviously don't have the phone yet but I thought it might be good to start this thread so we can keep each other updated on any problems with the factory unlocked devices as they start coming in.
