Use a high speed connection

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