Tesco Mobile 5G Review 2021: Download Speeds & Network Coverage

Using O2 as its network provider, Tesco Mobile offers 5G download speeds with competitive prices. Let’s dig a little deeper and learn more about Tesco Mobile’s 5G.


Latest Offer: 100GB £17.50 p/m!

Tesco Mobile is offering a great deal with 100GB of data for just £17.50 a month w/ Clubcard perks. The O2 powered network offers unlimited minutes & texts, access to 5G and EU roaming at this great price!

There are many MVNOs (Mobile virtual network operators) in the UK, but only a few of them provide 5G coverage to their customers and Tesco Mobile is one of them. Launched back in October 2019, Tesco Mobile uses O2 as its 5G network provider and offers four different 5G tariffs to choose from. The network’s customers have access to 5G coverage in 155 UK towns and cities. However, this doesn’t mean 5G is available in all areas of every city and town, therefore you should make sure to check O2’s 5G coverage map before committing to a Tesco Mobile 5G plan.

This review includes Tesco Mobile’s 5G network coverage, tariffs with 5G download speeds and the network’s overall 5G service.

5G Plans and Pricing

Currently, Tesco Mobile offers four 5G ready tariffs. Tesco Mobile’s 5G plans start at 5GB with 5000 minutes & texts and can go up to 100GB with 5,000 minutes & texts.

All Tesco Mobile 5G Plans are 12 month contracts

Tesco Mobile’s 5G service doesn’t come at no extra cost. This is unlike Three, which provides 5G to all its customers without any extra charges. Tesco Mobile charges around £5/month for access to their 5G network. On the bright side, if you’re a Tesco Clubcard Plus member you get double data on all Tesco 5G deals. Another benefit with a Tesco Clubcard is you can use your Clubcard points to pay your Tesco Mobile bills. And if you wish to spend your Tesco Clubcard points at Tesco Mobile you get double the value of your Clubcard vouchers. This means you can use a £10 Clubcard voucher and pay off your £20 Tesco Mobile bill. The same perk applies when you want to purchase a handset from Tesco.

Of course, you’ll need a 5G-ready device and also be in one of the areas with Tesco Mobile’s 5G coverage in order to benefit from the network’s 5G perks. You can purchase your 5G device from any store, but Tesco Mobile currently offers four 5G ready handsets too.

5G Download Speeds

Tesco Mobile’s 5G network is powered by O2, which means both networks offer the same download and upload speeds. Tesco Mobile claims the network’s 5G download speeds are about 10 times faster than their average 4G download speeds.

According to OOKLA’s (speedtest.net) October 2020 test results O2 offers the second fastest 5Gdownload speeds in the UK with 176.9Mbps. The carrier’s 5G service seems to be averaging around 150Mbps to 200Mbps. The average latency also seems to be below 10ms with Tesco Mobile’s 5G, which is great, especially if you’re a mobile gamer.

You might still want to read our EE Review, as EE seems to offer the fastest 4G download speeds alongside Three. The network also has the widest 5G coverage in the UK. Having said that, at the time of writing Three is the fastest 5G mobile network in the UK with 201.1Mpbs download speeds.

5G Coverage

As we stated above Tesco Mobile is running on O2’s network, so both networks offer identical 5G coverage in the UK. The carrier’s 5G is now live in 150 towns and cities in the UK, adding the likes of Aberdeen, Brighton and Oxford to the locations covered. O2 seems to be laying strong foundations for their 5G services and Tesco Mobile customers will benefit from these too. O2 aims to roll out 5G coverage in more cities and towns soon.

Of course, all 5G Tesco Mobile plans offer 2G, 3G and 4G coverage where 5G coverage isn’t available yet.

5G Locations

Aberdeen, Ashford, Banstead, Basildon, Belfast, Birmingham, Bradford, Brighton, Bristol, Cardiff, Chatham, Chesterfield, Coventry, Dartford, Derby, Dundee, Eastbourne, Edinburgh, Esher, Gateshead, Gillingham, Glasgow, Grays, Hemel Hempstead, Huddersfield, Hull, Leeds, Leicester, Lisburn, Liverpool, London, Lowestoft, Luton, Manchester, Mansfield, Middlesbrough, Newcastle, Newtownabbey, North Shields, Northampton, Norwich, Nottingham, Oxford, Peterborough, Plymouth, Rainham, Redhill, Rotherham, Sheffield, Slough, South Shields, Stoke-on-Trent, Sunbury, Sunderland, Thundersley, Warrington, Weybridge, Windsor, Worthing, York.

As we stated earlier in this article, Three offers 5G in more destinations and proposes wider coverage in the areas they support 5G. You might want to read our Three Review to learn more about the network. If you get the best 5G coverage from O2, but don’t want to commit to a Tesco Mobile plan, you can read our Sky Mobile reviewSky is also powered by O2, meaning they offer the very same network coverage.

If you’re a frequent traveller and find yourself in Germany, Ireland or Italy, Vodafone’s 5G is live in these countries and you can use it at no extra cost. Read our Vodafone Review to find out more!


Do I need to buy my 5G phone from Tesco?

No you don’t have to purchase your handset from Tesco. Tesco Mobile provides 5G coverage as long as your device is 5G ready.

Is 5G safe?

Yes, 5G is safe to use. The World Health Organisation (and other health organizations) performed many studies and tests and found that 5G isn’t harmful to health.

Where is 5G available in the UK?

This depends as each major network provider offers 5G in different locations and towns. Currently EE offers 5G in 125 cities and towns. O2’s 5G coverage is live in 150 cities and towns followed by Three with 193 locations and Vodafone with 57.

Can I use Tesco Mobile’s 5G abroad?

Unfortunately, no. Only Vodafone and its low-cost sub-brand VOXI provide 5G coverage when roaming internationally. You won’t get any 5G coverage with the other networks outside the UK.

Will 5G come to giffgaff?

Just like Tesco Mobile and Sky Mobile, giffgaff is also powered by O2, however, the network doesn’t offer any 5G services yet. We know for sure that 5G is coming to giffgaff though, we just don’t know when. You can still read our giffgaff review to find out what else the network has to offer.
