Had my Note 3 for a few days now and starting to get a little frustrated. I can't send MMS messages to anyone: tried sending pictures to another android user, tracfone user, iPhone, a fellow Note user, and it won't send to any of them. I've tried restarting my device, ensuring mobile data is turned on, removing battery and sim and reinserting, changing picture size, nothing works. My internet works (both Wifi and 4G), I can send and receive text messages fine, but I can't send at all, and receiving is a hit and miss where sometimes I'll receive it, though most of the times, I won't. Any help?
Edit: Have an AT&T phone
