Save on data roaming costs

You can cut data roaming costs and save on your phone bills by changing mobile data 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. Your network service provider can charge you
a fixed fee for data transfer or on a pay-as-you-use basis. To use the optimal connection
method, change the Wi-Fi, mobile data, and email download settings.
Using a Wi-Fi connection is generally faster and less expensive than using a mobile data
connection. If both Wi-Fi and mobile data connections are available, your phone uses the Wi-
Fi connection.
