The functions above may incur additional network charges from your
network carrier. Extra fees may also be charged in roaming areas.
Data usage
The first time you turn on your phone with your SIM card inserted, it will automatically
configure your network service: 2G, 3G, 4G or 5G.
Data saver
By enabling Data saver, you can reduce data usage by preventing some apps from
sending or receiving data in the background.
Cellular data
If the network is not connected, you can turn on
Cellular data.
If you do not need to transmit data on cellular networks, turn off Cellular data to
avoid incurring significant charges for data use on local carrier cellular networks,
particularly if you do not have a cellular data agreement.
Data usage is measured by your phone, and your carrier may count
differently.
VPN
Virtual private networks (VPNs) allow you to connect to the resources inside a
secured local network from outside that network. VPNs are commonly deployed
by corporations, schools, and other institutions so that their users can access local
network resources when not inside that network, or when connected to a wireless
network.
To add a VPN
• Tap Settings > Connections > VPN and then tap .
• On the screen that opens, follow your network administrator's instructions to
configure each component of the VPN settings.
• Tap SAVE.
The VPN is added to the list on the VPN settings screen.
Before adding a VPN, you should set a screen lock for your phone.
