Suddenly my galaxy note II will not send my pictures in a text. It wants me to check the apn settings. Ok., I went there and the only thing in the list is att mobile. The dot is checked & green. When you press on the att listed the information comes up, but cannot be altered because it is not highlighted to to so. So question is., #1it was working fine, and now not, what happened? And #2 how do I change mms settings when part of that is to change APN settings and can't! I can't send a picture! Thus sucks. Help! Anyone else have this issue?
