Just switched to TMO from AT&T - Please help

[windorf]

So as the title says, I just switched to T-mobile from AT&T. I thought the change was going to be seamless. But i'm pretty bummed that wifi calling doesn't work anymore. What else is going to be affected? Will I eventually get updates pertaining to T-Mobile software? What should I do, any recommendations on where to go from here with it? At least i'm not coming from Verizon I just read it's bad coming to T-mobile from there.

I suppose you'd have to verify that the APN for T-Mobile is set on your device. That might take care of the WiFi calling and the TMO-specific features. I expect that you likely won't get updates from TMO. You may not get them from AT&T either. In that event, you'll have to use Samsung's Smart Switch for updates.

I'd expect that moving from AT&T would be a lot better than moving from Big Red. At least your phone has the frequencies available to work on the TMO network. It's a crap shoot with a Verizon device on a GSM network.
