Want to save on your phone bills? You can cut 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 WiFi, mobile data, and mail download settings.

Using a WiFi connection is generally faster and less expensive than using a mobile data connection. If both WiFi and mobile data connections are available, your phone uses the WiFi connection.

On the start screen, swipe down from the top of the screen, and tap active WiFi connection icon.

  1. Make sure WiFi networking is switched to Ontoggle on icon.
  2. Select the connection you want to use.
