People Outside of T-Mobile Not Receiving My Texts

This is definitely a known tmobile issue. I have been having this issue (primarily with att users) for several months. I have 4 phone lines (both iPhone and android)  and I am constantly on my phone so it has been a big problem for me and I have also been a good case for tmobile to study. The problems are intermittent. I have submitted 3 official repair tickets been to multiple store locations and gone through all the troubleshooting steps possible over the course of more than a dozen calls to tech support. As a last resoort tmobile sent me a replacement phone for my main device (galaxy ultra s22+). Of course that didn't work either. At this point I am waiting for tmobile to make changes to their network settings to fix the issue and to extend to me a credit for all that I have been through. Since it has been so long (and they've tried to blame everyone else for all this time) I am not holding my breath for either a network repair or a credit. But I have informed them that I will continue to demand it. I am prepared to sue then if needed. Although again, my odds are probably slim to get fair compensation. 

The reason for my long post is to let everyone know about my experience and to save you all some of the trouble and confusion that I have endured. It isn't your phone, the other person's phone or carrier.... it is the tmobile network and there is nothing that anyone else can do but them. And they are well aware. 

Hi everyone! As of late Wednesday, it appears that people who do not have T-Mobile aren’t receiving my text messages. To me, they look like they’re sent, however, both Verizon and AT&T customers aren’t receiving anything on their end.

I spoke to T-Mobile via Facebook and I’ve done the following:

• Cleared cache on phone
• Cleared cache and data on messages app
• Made sure all apps (Google Play and Galaxy Store) were up-to-date
• Made sure phone was up-to-date
• Reset network settings
• Reset all settings
• Deleted all messages in my phone (and emptied the trash)
• Turned on and off airplane mode
• Turned on and off most connections/network type settings
• Restarted my phone way too many times

They told me I can come in-person today and get a new SIM card. I’m hoping that fixes it, however, I’m wondering if anyone else has had the same problem or has ideas? T-Mobile says my account looks fine and everything on their end looks fine. My phone is a Galaxy S21 and is only 1.5 years old, and I’ve been with T-Mobile for years.

Here we are and I’ve made countless phone calls to tech people. Been into a T-Mobile store (not helpful) and done ALL the things and still nothing. I’m having to write a text, take a screenshot of it and send it as a pic because that’s the only way I can text a non-t-mobile Android phone. It would seem to indicate a T-Mobile issue since I can in fact send an SMS to an android owning T-Mobile person. 
 

But the latest is to call them and speak to a Senior Advisor… and then a (refurbished) replacement phone which I kinda think is a bit off… not my fault the phone/network isn’t working. At the least it should be a new phone. But hey… I’m just a customer. Paying for service I’m not getting. Next stop after my next phone call to the tech people is the FCC cos this is ridiculous.
