MetroPCS annonces new "simpler" unlimited 4G plan for $603
500MB of 4G data a month after which you are throttled. Pay $50 a month and you will receive the same unlimited talk and text plus 2.5GB of 4G data for the month. Exceed that total and your data speed is reduced. MetroPCS does have an unlimited 4G data package for $60 a month and that includes unlimited talk, text and 4G data.
MetroPCS, like other pre-paid carriers, has worked hard to bring popular handsets to its customers, such as the Samsung Galaxy S III which can be purchased sans contract for $499.99. Other Android phones are available from manufacturers like ZTE, Huawei and LG.
