And -is your phone from AT&T or Cingular???

 

The message is code error. It does not say that code restriction is in place, just that the code entered was not correct.

 

The question was-Cingular or AT&T(phone locked to)?

#pw+894 051 311 263 407+7#
for AT&T

 

And code #pw+717 060 033 513 711+1# correct also,but for Cingular(phone locked to).

 

The phone is from cingular.

Thanks for the help.

 

Thanks for the reply.
