T-Mobile: All Band 12 LTE devices on our network must support VoLTE, E911
August 28, 2015
T-Mobile US (NYSE:TMUS) is not forcing smartphone makers to drop support for its 700 MHz A Block spectrum using LTE Band 12, as some reports have indicated, but it does require that OEMs that want to include Band 12 support also support Voice over LTE and E911 capabilities.
The carrier clarified its position after an Android Police article claimed that, according to a post on Reddit, a Motorola Mobility support representative said that Motorola dropped support for Band 12 in the new Moto E phone because it also did not support VoLTE -- at the behest of T-Mobile.
T-Mobile spokesman Viet Nguyen said that T-Mobile does not have a policy of asking device partners to pull Band 12 support. Motorola, in the process of developing a Band 12-capable device, did not fully go through the carrier's VoLTE and E911 certification process, and the OEM apparently decided to drop Band 12 support as a result.
