As of right now the settings that used to allow me to send and receive are now only allowing me to receive. This is my issue, a setting that works perfectly one day doesn't work the next day. There's no way to efficiently test MMS if it is that temperamental. Further more, time and time again I see others saying the MCC should be set to 310 and the MNC set to either 004 or 016. On my Droid 4 running ICS those settings WILL NOT WORK because the phone hides them from the APN list. It ONLY accepts 311/480.
