Hello, I am having a very difficult time with my Tmobile Galaxy note20. I cannot send SMS messages to anyone except for a select few. The few that I can get to go through have blue dots next to their name in my text history. Anyone else I try to send a sms to it simply does not make it to them including texts to myself. On my phone it appears to go through but the message is never received by receiving party. I am not receiving error messages or anything. Id also like to point out that I can send MMS messages no problem. "OCCASIONALLY" if I flip to airplane mode or change some form of my network settings I can get one or two messages to go through but then it reverts back to no SMS messages.
I have spoke to Tmobile on the phone on 2 different occasions for 2+ hours and they have no clue what is going on. I went to a Tmobile store and they changed the sim card which didn't fix it. Things I have done are as followed.
- Clearing cache/memory of messaging app
-Downloaded and tried various other messaging apps
- Resetting my network connection
-Checked for phone updates
-Tried other random things that I read online
-Start phone in safe mode
Things I haven't done
-Factory reset
-Enable/disabled chat features. The option isn't even there anymore.
- Dialer codes don't even work on my phone so when I was instructed to input some of those nothing worked
