SMS Not working. Network issue
Long story short, MMS works, data works, calls work, texts coming in from 5 or 6 digit numbers work, regular texting between 10 digit numbers does not work at all.
Remote support has done everything up to factory reset my S21. No dice. I put the sim card into my old S5, and still have the same issue. Got a new sim card. Still not working. Tried a friend's sim card in my S21, can text fine.
So. Something at the network level is blocking my texts.
What may have lead up to this.... for a few weeks I kept getting texts saying STOP from a bunch of random numbers. One person was nice enough to mention they were getting unwanted messages from my number. I definitely haven't sent any. Also ran half a dozen malware scans on my phone, nothing funny on there.
So, I'm guessing someone hijacked my number, and its now blocked on the network....
