ATT 920 unlocked on TMo texting issues post-Black

I'm not able to receive group texts after the Black update yesterday. Anyone else with an unlocked ATT 920 on TMobile having this issue?

Can't send picture messages, either.

Looks like the fix was to switch Access Point to the built-in Tmo LTE setting, not the custom one I had set up that was working.

Glad you were able to fix it.

I have been thinking about going to T-Mo since AT&T are removing things from the Lumias and just buy international versions of the phones.

I've always had this problem since day 1 of getting my unlocked 920 for tmo. What do I do? Cust serv is not helpful at all. Thanks
