How to tell if my phone is unlocked?

Borrow a SIM from a friend who has an account with a different GSM wireless service provider (T-Mobile, AT&T, Cingular) and see if you can make a phone call. If it works, and your phone thinks it is his (or her) phone with that phone's number, then your phone is already unlocked. But if it creates some sort of error message and doesn't work, then your phone is locked.

Remember, unlocked cell phones do not come with carrier specific internet installation since it varies from provider to provider. Since MMS is the transfer of data via internet, internet installation is required for MMS to work. Our certified technicians may be able to install both internet access & MMS on your phone. We provide this option during your initial purchase, and may be able to install wirelessly over the air for qualified phones. There is a small service fee, contact us for further details.
