Save on data roaming costs

Want to go easy on your phone bills? You can save on data roaming costs 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 mail download settings.
