Make/model: Nokia 6230b IMEI# 353372001898689 Country: USA Provider: Formerly Cingular Wireless; phone now says AT&T Also, for this phone on that network do I need to put another carrier's SIM card or just leave the SIM card out? Thanks in advance
you get 4 chances to unlock here is cingular first #pw+047 943 067 541 155+7# this is the AT&T one now so try both #pw+947 542 060 567 554+7# and yes leave your own sim in to unlock first
Can you help with codes for unlocking two Nokia 6230b phones? They are with formerly Cingular now AT&T Thanks Make/model: Nokia 6230b IMEI# 355032000770630 and Make/model: Nokia 6230b IMEI# 355032000306650 Thanks ... in advance!
This nokia phone was Cingular/AT&T. It is locked to Cingular/AT&T. I have since switched phone providers and got a new phone. The SIM is now deactivated as it was Cingular's. I want to know if I should leave the old SIM (the Cingular one) in there when entering the codes or put another SIM in there from a different carrier or take out SIM altogether.
It worked. I used the Cingular's unlock code. The SIM that came with the phone was a Cingular's chip even though the phone had AT&T in the display screen. My phone is only 1.5 yrs old and looks brand new. At least now I have a backup phone to use on my new Carrier's network, T-mobile. THANK YOU!
