The M920 is still a mystery for the most part but if it is to follow the trends of their previous offerings then this will more than likely be an Android-powered smartphone. The LTE bands that it supports are 1700/1900MHz which is the reason all fingers are pointing towards MetroPCS. In addition to LTE the M920 has tri-band CDMA support.
When the Huawei M920 finds its way to MetroPCS, it will be their first 4G handset to come to the states. There is no word yet on tech specs of this device and nothing regarding a timeframe of its release or pricing due to the fact that it is yet to be announced.
