Well my v2 module showed up tonight and I'm having no luck getting it to work with my H2O sim card. I can get the module up and running to the point where I can SMS back and forth with it to set command and make queries, but I can't get GPRS to fire up no matter what I do. From what I can tell, I should be able to issue the following command and everything should start working:
GPRS att.mvno - -
But the module will never connect to GPRS after this point. Anybody have any tips, or should I just toss the H2O sim and try out another vendor? Argh....
