Google Mobile search, in the palm of your handUse Your GSM phone on any compatible network
GSM cell phones are designed to work with any service provider.
In theory, all you need to do is swap the SIM account card in the phone.But some service providers 'lock' the phone they sell you.Don't worry - we can help you unlock your phone.
If you own a GSM type cellphone 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.
Here's how to simply and quickly unlock your phone so you can use it with any GSM service provider and SIM, anywhere in the world.
Phones are naturally unlocked, but a service provider might lock them.
When originally manufactured, all GSM cell phones are unlocked.That is, they can be used with any SIM from any cellphone service provider - always assuming, of course,that the cellphone service provider has compatible GSM service on the same frequency bands that the phone can operate on.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 highroaming charges when you take your phone out of their network and use it elsewhere in the world.
Fortunately, this locking is reversible. With some phones, it is possible to simply enter an unlocking password codeinto the phone and it is immediately then unlocked. Other phones need to be connected up to a special unlocking data terminal.
