Select network mode

3G (UMTS) or 4G (LTE) enables you to achieve higher data speeds than when using 2G (GSM). If you select LTE/WCDMA/GSM (auto connect), your mobile phone automatically switches between the three network modes provided you're within range of a 4G network. If you select WCDMA/GSM (auto connect), your mobile phone automatically switches between the two network modes provided you're within range of a 3G network. If you select WCDMA only, your mobile phone can only connect to 3G networks. If you select GSM only, you can't achieve high data speeds.

Tap LTE/WCDMA/GSM (auto connect), WCDMA/GSM (auto connect), WCDMA only or GSM only.
