What am i missing?
bought a straight talk iphone and put my att sim card in it. having trouble activating it. What am i missing? It keeps telling me the server is temporarily unavailable.
Since you purchased a straight talk iPhone, it would naturally be locked to Straight Talk. you would have to ask Straight Talk to unlock it (an unlikely outcome).
If you want an AT&T iPhone, buy an AT&T iPhone either from Apple or AT&T.
