Hi my friend gave me an AT&T Galaxy S phone. I don't want to add AT&T data plan, but I still want to be able to send/ receive multimedia message. I try to add new APN to select only mms (instead of internet+mms), but I can't select my new added APN as my new default. I think my phone was pre-programmed by AT&T or something. The default APN was called "ATT WAP", and I can't edit this APN setting. I tried to call AT&T, but all they tried to do is forcing me to add data plan to my smart phone. Can anyone help me?
