Why not make the most of your network connections? Use a 4G connection, when available and if supported by your phone.
- On the start screen, swipe left, and tap Settings > mobile network.
- Switch Highest connection speed to 4G.
When using your phone in an area where 4G might not be available, switch to 3G. This also helps your battery last longer, as your phone won't try to connect to the 4G network unnecessarily.
You can also select the network manually. Tap Network selection.
