Managing network types and supported bands on Windows Phone

Sometimes it can be necessary to configure your smartphone to work only with the networks with concrete frequency (for example, 900 MHz) or concrete type (GSM, UMTS, LTE). It can be useful because you can save the battery life of your phone. The great thing is that you can easily configure network types and supported bands using Field test mode as in Windows Phone 8.1, as in Windows 10 Mobile.

4) Choose the supported bands you need

Keep in mind, that if you will enable, for example, only 4G, it’s possible that you won’t be able to get any SMS or phone calls (it depends if voLTE, voice-over-LTE technology is supported in your country). So, for example, if you want to download something using 4G without switching to 3G, but you still want to get SMS and calls, don’t forget to choose GSM too.
