Ok so lately, people have not been receiving my MMS messages and I have not been receiving theirs. It is becoming a pain. It seemed the problem became more rampant after the 4.3 update but I do not know if that is the culprit. I doubt it. I've restarted the phone, pulled battery, cleared cache, cleared out all the texts, etc and seems to not work. And I am using the stock message app. On TMobile. Is the only other step to do a factory reset? Any help would be appreciated.
