Cannot send or receive MMS messages
I have an LG Shine. Recently, I got the unlimited messages feature. When I first got my phone, I told them to make it so my phone could not go on the internet so I wouldn't accidentally buy a ringtone or something like that. Now, I cannot send or receive MMS messages. When I try to send one it says "Service Unavailable" even when I have full 3G service. When I recieve one, I click "Get", but once again it says "Service Unavailiable". How can I make it so I can send/download MMS messages?
