How do I check my mobile internet usage on my phone?

You can check your usage in your device settings.

• Android: Settings > Connections > Data usage.
• Windows Phone: Settings > Data Sense
• iOS: Settings > Mobile network.

On an iPhone, also make sure to check if the feature “Wifi assistance” is deactivated. You’ll also find this in Settings > Mobile network, all the way down at the bottom. If this is activated, your device will automatically switch to mobile data if the Wifi signal is too weak or drops.
