An internal document allegedly obtained from T-Mobile says the iPhone offers a “poor” customer experience on T-Mobile’s network. While it’s arguable that is a true statement since current iPhone models don’t support T-Mobile’s 1700MHz and 2100MHz 3G/4G bands and can only run on a second-generation EDGE network, there are now well over a million T-Mobile customers currently using unlocked iPhones on its network. The internal document instead asks customer service representatives to suggest customers buy T-Mobile’s 4G HSPA+ Android devices instead. We certainly understand where T-Mobile is coming from; obviously it wants to be able to control its customers’ experiences on its network. Plus, EDGE is far slower than the carrier’s HSPA+ network. As TMoNews points out, it’s more probable that customers find their data experience “limited” but not “poor,” given that some customers may argue that the iPhone itself offers a better hardware and software experience than several of T-Mobile’s 4G phones.
