Ok, my friend and I are both on the AT&T network.
I have a pantech slate (I can send and receive mms)
My friend has a razr v3xx (He can't send or receive mms)
I was able to take my sim card and put it in his phone, and send a mms, while when his sim card is in his phone, he can't send/receive them.
I haven't tried putting his sim card in my phone yet, but I might try that tomorrow.
So my question is: Does anyone have an idea as to what the problem is, and how to go about fixing it?
My guess is it is something with his service, since when I put my card in his phone everything works fine.
I couldn't tell you if he can connect to the internet on his phone, because neither of us have a data plan, so I didn't want to try that.
