won't begin until next month although a specific launch date and price for the phone needs to be released. Since there is no two-year contract to sign, buyers of the Samsung Galaxy S III on MetroPCS should be prepared to pay up for the handset. One MetroPCS customer won't have to pay for the phone, however. The carrier is offering a free Samsung Galaxy S III as the prize in a contest, and all you have to do is give the carrier your name, address and phone number.
MetroPCS is the fifth largest carrier in the states and even offers 4G LTE service. For $70 a month, you can get unlimited music from Rhapsody, unlimited calls, text and data. Other lower cost plans offer a certain amount of data at 4G LTE speed which gets throttled once you go over your monthly data cap.
