New research by Which? and OpenSignal has found that mobile phone customers in the north east of England have the best chance of getting a 4G mobile phone signal.

Unique analysis of over 500m data readings, taken from over 30,000 users of the OpenSignal app, revealed that phone users in Middlesbrough were able to access a 4G signal 82.7% of the time. That meant it came first in our rankings of 4G availability across 20 of the biggest cities in the UK.

Best networks for 4G – see which phone networks impressed when OpenSignal analysed 4G speed and availability across the whole of the UK.

Rank	City	Average 4G availability
1	Middlesbrough	82.7%
2	Sheffield	79.3%
3	Sunderland	79%
4	Leicester	78.6%
5	Leeds	78.2%
6	Liverpool	78.1%
7	Newcastle	77.9%
8	Birmingham	77.5%
9	Glasgow	77.5%
10	Edinburgh	77%
11	Bristol	75.9%
12	Manchester	75.3%
13	Brighton	75.2%
14	Coventry	74.8%
15	Stoke-on-Trent	74.3%
16	London	73.6%
17	Nottingham	73.3%
18	Cardiff	71.8%
19	Southampton	69.6%
20	Bournemouth	67.5%

Sheffield came second in our rankings, with residents able to access 4G 79.3% of the time, and Sunderland was third.

Surprisingly, London only came 16th while phone users in Bournemouth had the least chance of getting a 4G phone signal of the 20 cities we analysed, only able to access the faster speeds it offers 67.5% of the time.

However, residents of all 20 cities enjoy a better 4G experience than the UK population as a whole. Poorer coverage in more rural areas means that the average UK phone user can only access 4G 65.1% of the time – though our analysis shows that this is getting better.

4G speeds

Yet, while phone users in Middlesbrough have the best chance of getting a 4G signal, the average 4G speed that they receive – 20.8Mbps – is one of the slowest that we tracked in our city-level analysis.

And while this speed is still faster than many home broadband connections, it only placed Middlesbrough in 15th spot in our rankings.

Rank	City	Average 4G speed
1	Stoke-on-Trent	26.6Mbps
2	Coventry	24.8Mbps
3	Leicester	24.4Mbps
4	Liverpool	24.4Mbps
5	Nottingham	24.2Mbps
6	Birmingham	24.1Mbps
7	Manchester	23.4Mbps
8	Bournemouth	23.1Mbps
9	Sunderland	22.8Mbps
10	Southampton	22.6Mbps
11	Newcastle	22.5Mbps
12	Leeds	22.5Mbps
13	Glasgow	21.9Mbps
14	Sheffield	21.3Mbps
15	Middlesbrough	20.8Mbps
16	London	20.5Mbps
17	Edinburgh	20.4Mbps
18	Bristol	18.8Mbps
19	Cardiff	17.7Mbps
20	Brighton	17.6Mbps

Instead, phone users in Stoke-on-Trent experienced the fastest average downloads, enjoying speeds of 26.6Mbps. Coventry came second in our rankings (24.8Mbps) and Leicester third (24.4Mbps).

Again London performed relatively poorly, with phone users there restricted to an average speed of 20.5Mbps. This compares to an average speed across the whole country of 22.9Mbps.

Our analysis

The information used in this analysis comes from a regular collaboration between Which? and mobile phone benchmarking experts OpenSignal.

We work together to look at the true mobile experience in the UK and monitor this by tracking the phone signal received by over 30,000 users of the free OpenSignal app. This latest report covers their experiences from 1 December 2016 to 28 February 2017 and is based on over 500m signal readings.

We've also used the data to build an interactive coverage checker. You can use this free tool to find out which network offers the best phone signal where you live.
