What are digital phone lines?

Digital phone lines let you make and receive calls over a digital connection, usually through your broadband router, rather than a wall socket.  

For most people, the change is likely to be straightforward. Your phone service will usually work through a broadband router, and many households will be able to keep their existing number and handset. 

If your service provider contacts you about switching, don’t ignore it. Act now and avoid any last-minute issues. 

What you’ll need:

  • Broadband connection - your service provider will explain what option is right for you 
  • Router or adapter - your service provider will supply this if needed 
  • Your current handset - many households will be able to keep using their existing phone 

If you have a phone line but don’t have broadband, your service provider will help you find the most suitable digital option for your needs.

Why are digital phone lines replacing copper and analogue?

The old landline network is ageing, harder to maintain and no longer meets modern needs, so the UK is moving to a more reliable digital system. 

Digital phone lines can provide you with a more reliable service, better-quality calls and smarter call blocking.

 

The switch off is happening

Frequently asked questions

  • Will my phone number change?

    You can usually keep your existing number. Speak to your service provider to check what applies to you.

  • Do I need a new handset?

    Many households will be able to keep using their existing handset, but some older phones may not be compatible. Your service provider can help you check.

  • What if there is a power cut?

    Digital phone lines need power to work. If you rely on your landline, have poor mobile signal or use telecare or health devices, tell your service provider so they can make sure you get the right support during the switch.

  • Can I still call 999?

    Yes. If you rely on your landline for emergency calls, speak to your service provider about what support or backup options may be available.

  • What about connected devices?

    If you have devices connected to your phone line, such as house alarms, CCTV, payment terminals, telecare or health alarms, check with the equipment provider that they are compatible with a digital phone line before you switch.
