Network Monitor

Get notified when you are using mobile data! This is the perfect app for people on metered data plans who want to keep closer track of their data usage.

When your phone switches from WiFi to mobile data, you'll get a notification. When your phone is back on WiFi, the notification will dismiss automatically.

Project Fi users - as an added bonus, this app includes a notification that tells you which carrier you are connected to (T-Mobile, Sprint, or US Cellular) while you are in the United States!

Get more detail on your cellular connection. View the mobile country code and mobile network code for your phone's current network. Also, keep track of your connection history with timers and a graphical history.

Permission explanations:

Phone - this app requires permission to access your phone so that it can detect changes in your cellular network state, whether you are using mobile data, and which cellular network your phone is connected to. This app does NOT make phone calls or send text messages.

Location - this app requires permission to access your location so that it can more reliably detect when your phone switches cellular towers. This app does NOT store your location or send your location back to the developer.
