In the My Viking app or through your My Viking account, your usage history is under the "Consumption" tab. Here you will find an overview of all data sessions, incoming/outgoing calls and incoming/outgoing text messages.

We cannot verify what your data has been used for. Most devices register your data usage so that you can check this.

Android: Go to Settings > Connections > Data Usage > Mobile Data Usage.
iOS: Settings> Mobile network > Mobile Data.

The definition of a ‘data session’ isn't as clear-cut as you might think. Your device does not start a new data session each time you open a new app or visit a website. Instead, it opens an active data session. Keep in mind that a data session can remain active for several days. This depends on the type of device you are using. A data session can be force stopped if you set your device to airplane mode or if you restart it all together.

The usage on your device does not always correspond to your actual usage. This may differ because the set period of your phone does not always match the start and end date of your bundles. You can always find the date of your bundle period on your bill. You can easily change the billing cycle via the data usage settings. That way, the consumption registered by your cell phone will be closer to your actual consumption. Please note, this usage remains indicative.
