My phone doesn't use a SIM card. Can it still be unlocked?
All GSM phones are used with SIM card, Subscriber Identity Module, a smart card that securely stores the key identifying a mobile phone service subscriber, as well as subscription information, preferences and text messages.|

What is Unlocking anyway?
Phones are generally sold by a wireless carrier for much less than their actual retail value. The wireless carrier often subsidizes the cost of the phone with the expectation that they can recover more than this amount throughout the subscriber's contract. They will try to make sure that the phone can only be used on their particular network, and thus, locks the phone's software to their wireless network.
Unlocking means clearing the phone's software setting so that the phone can be used on any network.
Why do I have to unlock the phone and what are the advantages?
Unlocking increases the resale value of your phone as it's not bound
to a particular carrier any more.
Unlocked phone is convenient to travel with, it can work with almost
any provider in the world - just swap the SIM cards. Subscriber can benefit from
purchasing a dual SIM card or
international prepaid SIM card in the visiting country/region as it might be less expensive than international roaming.
Wireless providers charge from 40 to 150 Dollars for an unlocking code.
Run two sim cards in one phone using a dual sim adapter.
