I've been looking at some awesome phones from Asia that have 4G LTE support (e.g. Elephone P3000s, Xiaomi Redmi Note), but I'm not sure if they would work on the Verizon network. Is there any way to tell if it will work? I've seen references to the frequencies supported by the devices, but I can't find any detailed specs of the Verizon network to give me any confidence.
Phones sold outside the USA will operate on a GSM network. Verizon is a CDMA network.
TThe only exception is the iPhone 6 or Nexus 6 which have radios for all networks.
Safest bet is to always buy a phone with a Verizon logo to begin with. Even Sprint phones, also CDMA, don't work or work well on VZW.
