SHAZAM! (yes, SHAZAM) MMS is enabled. 4-Steps, easy. Right now, you cant have both Tethering and Visual Voicemail working at the same time… so, thats a no go unless you like slow ass 3g internet on your computer more than you like a simple, sophisticated, and elegant way to check your voicemail.
I’ve also read a few sites that say that MMS works and doesnt work on a case by case basis. I have it enabled right now, but havent sent any messages because I live in the cow country where its still 1985 and the mere idea of cellular communication is like talking about teleportation and utilizing man made wormholes to manipulate spacetime. Stupid Hill Valley, where’s Doc Brown when I need him?
