Save on data roaming costs
You can cut data roaming costs and save on your phone bills by changing cellular data settings. To
use the optimal connection method, change the Wi-Fi, cellular data, and email download settings.
Data roaming means using your phone to receive data over networks that your network service
provider doesn't own or operate. Connecting to the internet when roaming, especially when abroad,
can raise data costs substantially.
Using a Wi-Fi connection is generally faster and less expensive than using a cellular data connection.
If both Wi-Fi and cellular data connections are available, your phone uses the Wi-Fi connection.

3. Select the connection you want to use.
Close the cellular data connection
