Because you want to change the wireless company you get service from in the US, and want to keep your present phone. You've changed to a different service provider and got a new phone, but you want to unlock your old phone so you can use it in an emergency just by swapping the SIM over if your main phone gives problems.

In areas like the United States where carriers offer free or deeply discounted phones with cell plans, the phones are commonly locked so that they will not work with other carriers. Carriers claim this is necessary to subsidize the cost of the phones. After a period of time, a carrier might agree to unlock the phone upon request, perhaps charging a fee.

No. Once your phone is unlocked, it remains permanently unlocked, no matter what you do to it, unless you specially program back the lock code into it.

Unfortunately we can't offer this as a service. If you live in the Fylde Coast, we can arrange a personal visit to unlock your phone. Please note in this instance the unlocking service will cost £20

Blackberry and Nec phones need to be shipped to us for unlocking. We shall unlock and ship your phone back.
