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 - they're not 100% accurate as signal strength can be affected by many things, like tall buildings or thick walls, but they will give you a good idea of the coverage you can expect in different areas. 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:

Tesco Mobile

Tesco Mobile

Tesco Mobile is the country's largest mobile virtual network, which means it uses another network - specifically O2. That's good news for customers, because O2 has very good 3G coverage across the UK. 4G coverage is less widespread and focused around major cities, but it's growing rapidly. Tesco offers 4G at no extra cost, so it's definitely worth checking to see if you can get it.

The People's Operator

The People's Operator

The People's Operator - or TPO, as it's easier to type - is virtual network. That means it uses another  network to deliver its services - in this case, EE. As such it has much the same coverage as Orange and T-Mobile, the 3G networks EE runs. Although 4G is EE's raison d'etre, TPO only offers 3G plans at present.

Asda Mobile

Asda Mobile uses EE's network. Although EE is best known for its wide-reaching 4G, this unfortunately doesn't extend to Asda Mobile - though it does offer 3G that covers 99% of the population.

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.
