I just bought a nokia 6030 (tmobil gophone) because my nokia 6030 voice mic stop working. I put my Cingular sim car into the new phone and it asks me for a security code. IMEI:011239/00/312478/2 model: 6030 type:RM-225 Maybe I am not allowed to use it because it is TMobil and not a Cingular? Any idea how I can find the security code? Thanks, Nestor ;-)
