If you get an unlocked phone, yes, you will be able to use it on MetroPCS as long as it's been converted to GSM in your area (since T-Mobile bought them). Just pop in your SIM and you'll have to either manually enter the APN settings to get it to work or can install Access Point, which will configure the APN for you automatically. You can always ask a sales rep on Negrielectronics.com questions about the phone to make sure it will run on Metro in your area. Shop for Unlocked Wireless Devices, Unlocked Phones, Unlocked cellphones and more - the reps are friendly and helpful.
