Samsung S7, ATT, cant receive texts

[grolson]

I have a Samsung S7, I cannot send texts, I cannot sign into Google because I cannot complete 2 step verification. Cannot download a new app either for same reason.
Any help appreciated, Samsung said it's a carrier problem, AT&T said it's a phone problem.
I tried a factory reset to no avail.

Test sending message using another device, if it works, then that's not Carrier's problem.
On your phone, check whether there's a file named 'Popui Receiver' in Applications System Files which should be there to allow messaging transmissions.
You might also check the Messages Center Number.

Texting is working again. It seems something changed in the APN settings. After correcting it it took a bit of time but all is working now.
Thanks for support!!
