Managing Your Mobile Phone
Note:
Accessing data services while roaming may incur additional charges. Ask
your wireless service provider about data roaming fees.
Switching off the Data Service
Things like synchronizing updates and receiving multimedia
messages rely on a transfer of data, which is what the data
service does.
1. On the Settings screen, touch Wireless & networks >
Mobile networks.
2. Clear the Data Service check box.
Switching on Always-on Mobile Data
If you have not selected Enable always-on mobile data, after
your screen is locked for 30 minutes, your mobile phone will
automatically stop all data services (except MMS). For example,
your mobile phone will not check new emails or synchronize
data in the background. The mobile phone will automatically
enable data services only after you have waken up your screen.
