T-Mobile to update certain devices to make them compatible with faster 700MHz band16
The Nexus 6 will receive an update allowing it to be compatible with the 700MHz band early this year. In May, the Samsung Galaxy Avant and the Sony Xperia Z3 will receive the update. And sometime this year, the ZTE ZMAX will follow suit.
Tablets that are compatible with T-Mobile's 700MHz LTE coverage include the Samsung Galaxy Tab 4 8.0 and the Samsung Galaxy Tab S 10.5. One other device, the T-Mobile 4G LTE HotSpot Z915, also supports the 700MHz band.
Last year, T-Mobile swapped cash and some AWS and PCS spectrum with Verizon, in exchange for 700MHz spectrum. The low-band signal travels farther and also has an easier time penetrating buildings.
