If your cell phone that you purchased at a discounted price when you signed up for service, the chances are that the cell phone company has 'locked' your phone so it will only work with their service. Most cell phone service providers electronically 'lock' the phone so that it can only be used with their service. There are obvious reasons why they choose to do this - in particular, to force you to pay what are usually very high roaming charges when you take your phone out of their network and use it elsewhere in the world.Fortunately, this locking is reversible. We can unlock your phone so you can use it with any GSM service provider and SIM, anywhere in the world.
