T-Mobile announced today that its MetroPCS prepaid brand will begin offering Apple's iPhone line starting tomorrow, July 1. iPhones will initially be available only at MetroPCS stores in the state of Florida. T-Mobile says nationwide availability for the Apple devices is said to be "coming soon".
In its announcement, T-Mobile lists the following prices for the MetroPCS iPhones: iPhone 5s $199, iPhone SE $349, iPhone 6s $649 and iPhone 6s Plus $749. Presumably those prices are for the base 16 GB models. There's no word as to whether or not MetroPCS will sell the 64 GB and 128 GB versions.
The iPhone 5s is discontinued and no longer available from Apple. Metro's $199 price a bit higher that the $149.99 that MetroPCS competitors Cricket, Straight Talk and Boost are charging. However Cricket's 5s is currently out of stock and Boost $149.99 price is after a $50 mail in rebate.
I don't know why it took T-Mobile so long to get around to officially selling America's most popular smartphone brand in MetroPCS stores. T-Mobile has positioned MetroPCS as its "fighting" brand battling for prepaid market share against Boost, Cricket and the various TracFone brands. The lack of iPhones put MetroPCS dealers at a considerable disadvantage in selling to Apple fans.
It also looks like MetroPCS has finally fixed a weird bug that broke WiFi calling, MMS, Visual Voicemail and VoLTE on the iPhone 6s and 6s Plus on MetroPCS. Those features worked on older iPhones on MetroPCS, but did not work on the current 6s and 6s Plus flagships until recently.
