Tesco Mobile 4G Coverage and Network Summary

Updated: November, 2016


Introduction to Tesco Mobile 4G

Tesco Mobile is an MVNO that uses O2. Because it uses O2’s towers it doesn’t need to worry about infrastructure of its own. As such you can also look at O2’s progress to get an idea of Tesco Mobile’s.

O2 currently has 4G coverage for over 70% of the UK population and aims to ultimately have at least 98% population coverage. Or, viewed another way, OpenSignal users on O2 have a 4G signal 55.97% of the time. By extension Tesco Mobile should have the same.

Tesco Mobile 4G Network Overview


Types of 4G from Tesco Mobile:

  • 4G – Typically 5 times faster than a standard 3G network.*

Tesco Mobile offers 4G that is around five times faster than a standard 3G connection. *4G speeds will vary depending on location and number of people using the service.

4G from Tesco Mobile uses the following network frequencies:

  • 800 MHz (0.8 GHz)

Tesco Mobile only has access to 800MHz spectrum, which can travel over long distances, so it’s good for bringing 4G to secluded, rural spots and for widespread coverage in general. It’s also adept at passing through walls for good indoor signal. But it doesn’t have as high a data capacity as some of the other frequencies, so theoretically it could fare worse in busy areas.

Roaming destinations

Tesco Mobile allows customers to roam in the EU using their monthly allowance, plus 4p per megabyte of data, 4p per minute and 1p per text.

Tesco Mobile 4G Coverage

Tesco Mobile shares coverage with O2, which currently has 4G in over 600 large towns and cities and thousands of smaller towns and villages. However the network hasn’t provided a full list of locations with 4G, instead directing people to its coverage checker to see if they can get 4G in their postcode.

Examples of places which do have 4G include Antrim, Basildon, Belfast, Bradford, Birmingham, Bridgend, Brighton, Burnley, Cambridge, Canterbury, Chelmsford, Coleraine, Colchester, Coventry, Derby, Edinburgh, Glasgow, Leeds, Leicester, Leigh, Liverpool, Livingston, London, Macclesfield, Maidstone, Manchester, Newcastle, Newtownabbey, Nottingham, Nuneaton, Pontypool, Poole, Portsmouth, Reading, Sheffield, Sittingbourne, Southampton, Southend-on-Sea, St Albans, Swansea, Tamworth, Winchester and York.

Of course with vast swathes of the UK covered that’s only a partial list, but you can check the coverage checker here for more and if you live in a city then you’re likely to have coverage in any case.

Recent locations to get an O2 and by extension Tesco Mobile 4G upgrade include:

Crick, Burton upon StatherBarton-upon-Humber, BraemarWhitehead, Clehonger, Crewkerne, Ilminster, Swarland, Westruther and Winterbourne.

    Generally tesco network is good, but the 4g is somewhat patchy as to why it’s at no extra cost,. You’ll need a hefty data plan as if you do get a 4g signal you’ll eat up your data allowance like there’s no tommorow

    Hmm after my testing it seems O2 DEFINITELY give priority signals to there own customers as opposed to Tesco Mobile customers. I’ve been testing an O2 and Tesco Mobile PAYG SIM card in a Nexus 5 and an iPhone 6S when walking my dog around the exact same walk for the last few days, the O2 sim in either phone gets a much stronger signal even 4G and confirmed its 4G with a speed test, then the Tesco Mobile sim in either phone gets which can only get 3G. I was in a main town on the top of the two level Tesco Store car park and Tesco Mobile still only got maximum strength 3G despite all checkers stating a maximum strength 4G signal was available, for both O2 AND Tesco Mobile.
    It seems in the UK the MVNO signals are treated as second class, or it could be agreed in corporation contracts due to the money being paid and never advertised to the customers.

    I think people need to be aware of this when considering an MVNO provider.
