Save on data roaming costs

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 Wi-Fi,

mobile data, and mail 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.

On the start screen, swipe down from the top of the screen, and tap .

1. Make sure Wi-Fi networking is switched to On .

2. Select the connection you want to use.

Stop data roaming

Tip: To save on data costs when traveling, save new maps to your phone before your journey,
