Most cell phone companies lock the network on their phone to prevent their customers from using the device with another provider. If you own a Nokia 6234 phone, you can unlock the device for free by obtaining the master subsidy lock (MSL) code from your provider. The MSL removes the network and allows you to activate the device with another carrier.
