About the mobile and broadband checker
This checker shows the broadband and mobile coverage availability for your address. It will also show the predicted speeds available for broadband.
The checker can also test your Wi-Fi and broadband connections and suggest tips for improving your speed. The checker quickly runs a series of tests and measurements from your smartphone or tablet to tell you how well your mobile or broadband connection is performing.
To get a complete view of the quality of your connection, we recommend running tests in different places, at different times, and on different devices.

The checker is also available in Welsh.
