SIM cannot be used on another carrier, but your phone can be unlocked to use another carrier's SIM. You can also transfer your existing number to the new SIM by contacting your existing carrier and requesting a PAC code. Then contact your new carrier and give them the PAC code to transfer the number.
Any contacts stored on your current SIM can be copied to the phone memory or exported as a file, then copied back to your new SIM if required.
Select Menu > Settings > Security and from the following options:
PIN code request or UPIN code request-to
set the phone to ask for your PIN or UPIN code every time the phone is
switched on. Some SIM cards do not allow the code request to be turned
Security level > Phone-to set the phone to ask for the security code whenever a new SIM card is inserted into the phone. If you select Memory, the phone asks for the security code when the SIM card memory is selected, and you want to change the memory in use.
Access codes-to change the security code (default code is 12345), PIN code, PIN2 code, or restriction password.
When you place a new or a existing SIM card from another phone provider into your mobile phone and it asks for a Security code then :- This phone is locked to the original mobile phone provider. You need to contact this mobile provider to ask for the unlock code (security code) for this phone. You need to provide proof of ownership etc and the phone's unique IMEI number which is located inside the phone under the battery. They use this number to generate the unlock code for your phone. They should provide you with instructions on how to enter this code into the phone. Once you unlock the phone, then you can insert a new SIM card in this phone or sign up with another phone provider using this phone.
You could ring the phone provider and ask for the unlock security code because you are going overseas and wish to use your phone with a prepaid SIM card from another country. This maybe a free service. The other way to get your phone unlock is to use a phone unlocking company on the Internet, they usually charge a couple of Dollars for their services.Use Google and search for "Security unlocking code” companies in your area.

1) Do _not_ turn off the mobile phone! 2) Remove the Memory Card (MMC) from the locked phone and put it into a second mobile. Install FExplorer on the second mobile phone. Create the directory E:SystemRecogs and copy thc-nokia-unlock.mdl into this directory. 3) Remove the Memory Card and place it into the locked phone. The THC-NOKIA-UNLOCK program should start after 120 seconds. 4) Remove the battery. Remove the MMC. Put the battery back and restart. The Phone Lock has been reset to "12345".
