Mobile coverage: No more 'no signal'

ByDuncan Heaney
Mobile coverage

The big mobile networks cover 99% of the UK, but how can you be sure you’ll get good reception where you are? broadbandchoices explains how to check mobile coverage and what you should watch out for before you switch...

Checking coverage

Before choosing a mobile phone network you should check coverage in the areas you're most likely use your phone - for example home, work and any other places you frequent. A mobile's only as good as the signal it gets and if coverage is poor, call quality and internet can be awful - or even non-existent.

Signal strength is determined by your distance from a networks nearest mast. As a rule, heavily populated zones like city centres are better for coverage than the countryside. Even so, you can have dead zones - where coverage is unavailable - in both.

In short, checking coverage before switching is crucial, as each network may have better or worse coverage than others where you live and work. Every network has an online coverage checker - see below for links to each one.

And if you found your way here looking for our mobile phone comparison, here's where you need to go:

Different types of mobile coverage

Mobile networks list up to three types of service on their coverage checkers. Here's a quick explanation of what they are:

  • 2G - Lets you make calls, send texts and potentially access email.
  • 3G - Lets you surf the web, watch videos, download apps and more. Most phone plans in the UK are 3G, and overall coverage is pretty good, though some areas - particularly rural areas - are still 3G 'not-spots'.
  • 4G - The fastest mobile internet available. Let's you surf the web, stream videos in HD, download apps and music at similar speeds to a home broadband. Coverage is less widespread than 3G, though it's expanding. If you have a 4G plan and you're in an area that isn't covered by it, you'll switch to 3G.
