What are locked/unlocked phones?
When you buy a plan from a carrier that comes with a free or heavily discounted phone, the carrier will lock the phone so that you can only use it with that particular carrier. Most of us use that carrier for the life of the contract and having it locked is meaningless. However, if you are travelling overseas and want to use your phone with a different carrier (see our page on using your phone overseas), or you have some other need to switch you SIM card to use a different number or different carrier with your phone, you will need to get it unlocked. A service like TravelInsider can provide unlocking codes for many GSM models.
Locked Phones:
Switch on your mobile phone with a sim card from a network other than the network you are currently with. If you are able to use the phone, you can be sure that your phone is not locked. If your phone displays an error message saying "Wrong sim" or "Incorrect sim" or "Emergency calls only", etc., then your phone is probably locked phone.
Unlocked Phones:
With the Unlocked phones,you can still use it with it’s existing network or switch over to any other supported network.With an unlocked phone, you can go to any country/state and save money by using a local network rather than paying high roaming costs to your home network.
