Cannot send MMS outside of T-Mobile network

Hi I'm having similar issues. It seems like this particular operating system has a conflict between RCS and MMS SMS. My older phone does not have this issue but this newer phone does. I got it to replace another phone I was having problems with like this and I thought it was the phone but I think it's maybe the operating system

One of the phone numbers on my account is unable to send pictures (MMS) messages to numbers outside of the T-Mobile network. This has been an ongoing issue. We've tried all the troubleshooting on the phone. They sent us a new SIM card and that has also not resolved the issue. Ever after the phone was upgraded, it's still having an issue. Is there anything that can be done?

It's frustrating to keep having MMS problems even after trying various fixes, replacing SIM cards, and upgrading phones. Verifying network settings and contacting T-Mobile customer service for individualized support may help to fix the issue. Effective communication is crucial for obtaining a precise diagnosis and a prompt resolution of the problem.
