How do I check mobile and broadband coverage?
Tap the “check availability” option on the app’s home screen.
- Mobile - you’ll find out the availability of voice, 3G and 4G services from your operator, and all others, in your current location. You can check both indoor and outdoor service coverage.
- Broadband – the app will show you the speed (download and upload) and availability of broadband services at your current location.
You can also view the availability of mobile and broadband services using the interactive availability maps.
How do I run a test?
To check your broadband performance, connect your device to your Wi-Fi network and select “run a test” within the app. It will then run a series of tests to check how well your Wi-Fi is performing.
If it finds any problems with your Wi-Fi or broadband connection, the app will provide tips on how you can improve performance.
To get a complete view of your household’s performance, we recommend running multiple tests in different locations, at different times and on different devices.
The fixed broadband data available in the apps and our online checker is also available via an API (https://api.ofcom.org.uk/). The mobile data will be available via an API from late December 2018.
