• LTE/WCDMA/GSM (auto connect) is the default network
mode option. This selection allows the device to choose the
fastest connection from among the available connection
speeds, including LTE.

network and choose from only 4G, 3G, and 2G networks.

• GSM only restricts your connection to only the 2G network.

instructions to connect to these network types.
