HTC One T-mobile prepaid wont send MMS

[sevy13]

Hey guys. For about 2 weeks now I have not been able to send MMS messages. I have and HTC One factory unlocked running on T-Mobile prepaid with LTE speeds at home. My data is always on and I have no problem searching the web. I have been searching threads for the past week and have found nothing to help me. I am able to receive photos perfectly good. I also tried sending myself a photo too. It went through and I received it but when I tried sending a photo to my brother he didn't get anything. My group messages won't go through either.
Thanks for the help!

Check your message service centre number & make sure it's correct. You may also need to get the configeration messages resent to your phone, your service provider can send u these or you can google them.
