I have the AT&T version of the S2, with ICS, and I have tried at least 20 different APN settings. Internet has worked with all of them, but MMS never works. Has anyone had any success with ST and a Skyrocket?
I used the apn settings I got with the SIM card and aside from once or twice, MMS has worked just fine. Send and receive. This is on an unlocked nexus 4.
