MetroPCS on Tuesday unveiled a “rough sketch” of LTE devices set to launch later this year. It’s a motley crew of variety, something for everyone, but perhaps the biggest device in the above picture is the Samsung Galaxy S III, which is doing quite well for itself around the world already. Another Samsung handset, thought to be the “Galaxy Mini,” is also arriving with VoLTE support — MetroPCS only just launched its Voice over LTE services earlier this month. In addition, the carrier is offering a lower-end Coolpad — maybe for just $149 — as well as a 4.3-inch ZTE device. As of now, there are no hard release dates attached to any of the devices, so we’ll be sure to keep our eyes open for any further details.
