When I travel abroad, will I be charged for data roaming?

WhatsApp Messenger uses the same internet data plan as web browsing and email on your phone. If using your cellular data while roaming will normally result in additional charges, you may be charged extra by your mobile provider for using WhatsApp while roaming. Contact your wireless carrier for details about international roaming countries, SIMs, rates, and policies. If you do not have an international data plan, turn off Data Roaming options to avoid data roaming charges.

To confirm that your data roaming is disabled go to:

Windows Phone settings > system > cellular or mobile network > Data roaming options and make sure to set the option to don't roam.

Provided you have Wi-­Fi internet access and active WhatsApp service, WhatsApp should be free to use over a Wi-­Fi connection. Please note that some Wi-Fi networks may charge you for usage.

If data roaming is enabled on your device, we suggest that you set media auto-download to Wi-Fi only to avoid extra data charges. To learn more about how to configure your media auto-download settings, please read here.

While traveling, we recommend that you set your WhatsApp status to "I am currently roaming abroad, will reply when I am on Wi-Fi". This way your friends will know why you are not answering right away.
