Broadband and mobile coverage checker

The mobile and broadband checker lets you:

• check indoor/outdoor mobile availability for voice, 3G and 4G services from all major providers
• view broadband availability and speeds for any UK address
• test the performance and speed of your mobile or broadband connection
• get tips on how to improve your internet connection or mobile coverage.

Enter a postcode to view mobile coverage by provider, or availability of broadband services (standard, superfast and ultrafast). You can also view the results as interactive maps.

If you can’t get a download speed of 10Mbit/s, you may be eligible for the broadband Universal Service Obligation (USO).

Want to check the network status in your area?

Our coverage checker cannot tell you about maintenance or reported issues in your area. Your provider may have this information on their website.
