All Nokia 6670 phones have unique unlock codes to remove the wireless network restrictions imposed by the wireless provider company. Wireless networks install a program that locks the use of SIM cards from other companies before issuing the phone. The unlock code lifts this restriction and permits the customer to use the mobile with any carrier. Many wireless companies will give you the subsidy unlock code if you have been a client for at least three months.
Instructions
1. Type *#06# on the 6670 to display the IMEI number. The IMEI distinguishes your particular device from all other Nokia 6670 phones and is required to generate a working unlock code.
2. Call the customer service number of your cell provider. Request the subsidy unlock from the customer service representative. Some companies have a policy that requires representatives to provide the unlock code to customers who have been with the company for a certain amount of time. Each wireless carrier has its own criteria, but it is usually between 60 and 90 days.
3. Turn off the phone and remove the SIM card from behind the battery. Insert the battery and turn the phone on.
4. Type #pw+CODE+1#, or #pw+CODE+7# for Canadian users, and the phone will display "Network Restriction Off." The phone is now ready for use on any network. Replace "CODE" with the subsidy unlock code provided by your cell provider.
