i thought about the same thing karl mentionned.
you see with dk3 you can see the sega account info but only edit the
user account infos.
there are 2 options where you can choose between sega/user, one is the
one you want to see/edit, the other one is the one you want to use.
if you have a doubt make sure both are on user.
then dont forget to save the settings to the internal memory before
leaving the menu.
hope that will solve the problem.

also for the at command just leave it blank, some people will say teel
you some at commands can speed up your modem but these are tales.
