I think I finally resolved my issue. Here are the steps I took to get it functioning again. 1. Contacted my provider and went through a troubleshooting item with them. They ended up reprovisioning my SIM and "reactiviating" the phone. This didn't fix the issue. 2.I started the phone in safe mode and tested the SMS, to rule out any third party apps. This didn't fix the issue. 3. Updated my SMSC # by dialing *#*#4636#*#* -> phone information -> scrolled down to SMSC -> tapped refresh to get the current number and then hit update. This didn't fix the issue. 4. Was about to do a factory reset but I first decided to put my SIM in an old LG phone that I had. As soon as I started the old phone I started getting a plethora of text notifications. I sent a few texts from my old phone and got a few responses. I then put my SIM back into my XA2, started it up and sent an SMS message. I then received a response SMS. I also sent an MMS and received a MMS response. I tried a few other friends and got responses. I am not actually sure what fixed the issue but everything seems to work at this time.

I have an unlocked Sony Xperia XA2 which can send text messages out to other phones but I can not receive the responses. I can text myself and receive them. I am stumped and really need to be able to message for work. I can make calls and use data, the SMS/MMS is what is jacked up. It has been working fine for the last couple of months and in the last two days this issue arrived. I use Android messages for my text. I uninstalled all of the updates and I still couldn't get any of the messages sent to me. So I reinstalled all of the updates and no change. My carrier is AT&T and they reprovisioned my SIM which did nothing. Any assistance is appreciated.
