I recently moved from Note 2 to Moto X. In Note 2, the 'Mobile Networks' page inside Settings had the 'Network Mode' setting with options: GSM/WCDMA (Auto mode), GSM only or WCDMA only.
In Moto X however, instead of 'Network Mode' there is 'Prefered network type' which has the options: 4G (recommended), 3G or 2G.
Through this I can force 2G, I'm assuming, but not 3G or 4G (there's no 4G in India yet anyway).
Is there any other setting or any app that can force only 3G (or 4G)?
