Update your phone software
No computer needed – update your phone software wirelessly for new 
features and improved performance.
Before starting the update, make sure your phone has enough battery 
power.
Using services or downloading content may cause the transfer of large 
amounts of data, which may result in data costs.
By default, your phone automatically downloads available updates 
whenever the data connection settings, for example roaming, allow it. 
When your phone noties you that an update is available, just follow the 
instructions shown on your phone.
 Tip: 
Check Store for app updates.
Turn o automatic update downloading
If you want to keep tight control of your data costs while roaming, you 
can turn o automatic update downloading. From the Start screen, 
swipe left, and tap   Settings > phone update > Automatically 
download updates if my data settings allow it.
Use a high speed connection
Why not make the most of your network connections? Use a 4G 
connection, when available and if supported by your phone.
1.  From the Start screen, swipe left, and tap   Settings > cellular.
2.  Switch Highest connection speed to 4G.
 Tip: 
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.
 Tip: 
You can also select the network manually. Tap Network 
selection.
