Mobile network
A mobile network connection allows your device to make calls and, if you have a data plan, use data services such as
Internet browsing.
If your device is set up for roaming and you travel outside of your service provider's wireless coverage area, in most cases,
your device connects to another service provider's wireless network automatically. If you're not sure whether your device is
set up for roaming, or what roaming fees apply, check with your service provider before you travel.
