First of all, call your carrier and ask nicely, if your contract has expired, they'll hopefully unlock your phone for you.
If you tell your carrier you'll be travelling and wish to use
a SIM card from another country to save on roaming fees, they may also unlock your phone for you.
It is important to note that not all devices are capable of being unlocked, often because of the manufacturers' device designs, and that even for those devices capable of being unlocked, not all device functionality may be capable of being unlocked. Specifically, devices manufactured with a SIM slot within the past three years (including, but not limited to, all Apple iPhone devices), cannot be unlocked to accept a different domestic carrier's SIM for use on another domestic carrier's network.
You can also unlock screen code and sim-card of Nokia E6 mobile phone. But you need to do first unlock code for it's operating system.
If the unlocking code is not working for Nokia E6, you need to enter your phone IMEI number to the box to get new one.
You might have to enter network settings (APN settings) for the new network, but usually 'big' network operators have an APN in the system software that will automatically be used. If you need to set a new APN, the people you bought your new SIM card from can help you. Don't worry, it's pretty easy.
