Your phone has to be unlocked to use maxSIM™. Many modern mobiles are supplied unlocked. If not, it is a simple procedure to unlock it.

To find out whether your phone is unlocked, insert a SIM card from a different network. If your phone operates normally it is already unlocked. If not, you can ask your operator for an 'unlock code' which it is obliged to give you, though conditions and charges may apply. Alternatively you can unlock it yourself by taking your phone to an independent phone shop or by trying one of the independent unlocking websites, such as:
