Tesco Mobile is an MVNO that looks to stand out primarily through good value plans and a large range of Pay As You Go options. It’s a fairly conventional network in most ways, but that’s no bad thing.
It’s an O2 MVNO, so as it uses O2’s towers it doesn’t need to worry about infrastructure of its own. You can also be sure of widespread 4G coverage, and it was one of the first MVNOs to offer 5G.
But there are various reasons you might want to choose Tesco Mobile over O2 – or any other network – and some reasons you might not want to. So read on for a full review and overview of the network.

Tesco Mobile has almost 100% population coverage with 4G, 3G and 2G, so you’re almost certain to get a signal. Speeds are variable though.
Use Tesco Mobile’s coverage checker above to find out more about Tesco Mobile's coverage in your area, including signal strengths and details on both indoor and outdoor coverage.

You’ll need a 5G phone and plan to take advantage of 5G, but Tesco Mobile offers both, with phones such as the Samsung Galaxy S21 and iPhone 12 (among many others) available at the time of writing. And it’s worth getting on board, as it’s far faster than 4G, speeds for which can be seen below.

Tesco Mobile (O2) |
18.2/6.2Mbps |
38.1ms |
As an O2 MVNO, Tesco Mobile uses standard 4G, which is roughly 5 times faster than a standard 3G network.
In an Opensignal report from October 2020, O2 was found to have average 4G download speeds of 18.2Mbps and average 4G upload speeds of 6.2Mbps, which in both cases is slower than any major rival, so you can expect Tesco Mobile to be similarly slow – though notably that’s still fast enough to comfortably do most things you might want to on a phone.
Its average latency meanwhile (how long it takes for the network to respond to a request), was found in an earlier April 2020 report to be 38.1ms, which has Three and Vodafone beat, but not EE.
For 5G, a Point Topic report from September 2020 suggests that O2’s average 5G download speed is 115.7Mbps, so again Tesco’s might be similar, and that’s a big upgrade on 4G speeds.

Tesco Mobile uses the 800MHz, 1800MHz, 2100MHz and 2300MHz bands for 4G. The 800MHz band is long range, so it can travel a long way between masts, but it’s also good at passing through the walls of buildings. Those two abilities combine to make it well suited to both urban and rural locations.
The 2300MHz band is more suited to busy areas but it’s shorter range, while the 1800MHz and 2100MHz bands sit in the middle capability-wise.
For 5G, Tesco has access to the 3400MHz band, which is the shortest range of all, but can cope with lots of connections.
You can find in depth details of this band and others in our 4G frequencies guide.
Tesco Mobile’s improvements are tied to O2’s, but there’s always stuff in the works there. Right now O2’s focus is on expanding its 5G coverage, which will also expand Tesco’s.
Tesco Mobile states – like most networks – that emergency voice traffic will always be prioritised on its network.
The network also notes that when it comes to data, “customers whose use is so excessive that other customers are detrimentally affected will be warned to adjust their usage or risk disconnection.”
However, beyond this traffic management isn’t generally used, even at peak hours.

Tesco Mobile offers Pay Monthly, SIM Only and Pay As You Go plans and all of them come with 4G at no extra cost. Tesco also offers 5G on Pay Monthly and SIM Only, but only on select plans. You can see more in-depth details of Pay Monthly and SIM Only above, while Pay As You Go is in a chart below.
Tesco Mobile’s Pay Monthly plans are a rarity in that you can choose a 12, 18, 24, 30 or 36-month plan, rather than only having 24-month plans available, and they come with a wide range of allowances, topping out at unlimited data each month. You can use as much of that data as you want for tethering.
Tesco Mobile also has a wide range of SIM Only plans, with data limits ranging from 2GB to unlimited. As you’re not getting a phone with them they’re cheaper than Pay Monthly plans. And as with Pay Monthly, any or all of your data can be used for tethering.
Tesco Mobile doesn’t currently offer any Data Only plans.
Overall the highlight of Tesco’s plans, other than competitive prices, is the wide range of durations available on Pay Monthly. Lack of extras such as VoLTE (explained below) is the main weakness.
Tethering refers to the ability to use your phone as a Wi-Fi hotspot, letting other devices share its network connection. This is allowed on Tesco Mobile and the only limit is your data allowance, which at the time of writing means you could use up to unlimited each month to tether if you’re on a top-end plan.
Wi-Fi Calling refers to calling and texting over a Wi-Fi network using your regular number, dialler and SMS apps. It’s especially handy if you’re somewhere with a Wi-Fi network but no regular signal, however it’s not currently offered by Tesco Mobile.
VoLTE (Voice over LTE) refers to making a call over 4G, rather than 2G or 3G. The ability to do this means you can make and receive calls in places with only a 4G signal, but it’s not currently offered by Tesco Mobile.

Tesco Mobile has a range of money-saving Rocket Packs available, all of which last one month and automatically renew. They each come with a bundle of minutes, texts and data, topping out at 40GB.
Additionally, Tesco Mobile has Triple Credit tariffs which triple your credit when you top up £10, £15 or £20.
That free extra credit is available once a month and lasts one month. It’s used before any paid top up. You can’t both be on a Triple Credit tariff and use Rocket Packs at the same time.
Outside your bundle you’re charged 25p per minute, 10p per text and 10p per megabyte.
Tesco Mobile's Home From Home service lets you use your allowances at no extra cost in the following 48 destinations:
Austria, Azores, Belgium, Bulgaria, Canary Islands, Croatia, Republic of Cyprus, Czech Republic, Denmark, Estonia, Finland, France, French Guyana, Germany, Gibraltar, Greece, Guadeloupe, Guernsey, Hungary, Iceland, Ireland, Isle of Man, Jersey, Italy, Latvia, Liechtenstein, Lithuania, Luxembourg, Madeira, Malta, Martinique, Mayotte, Monaco, Netherlands, Norway, Poland, Portugal, Reunion, Romania, San Marino, Slovakia, Slovenia, Spain, St. Martin, St. Barts, Sweden, Switzerland and Vatican City.
Based on the available data, Tesco Mobile seems well-rated for customer service. For one thing, in an Ofcom report covering 2019, Tesco was found to have the fewest complaints to Ofcom of any mobile provider, with just 3 for every 100,000 customers.
The report also found that 97% of customers were happy with Tesco Mobile overall, with 3% having a reason to complain, and 59% being satisfied with the way their complaint was handled.
Tesco Mobile has a wider range of Pay As You Go options than most networks, with bundles and plans to suit almost any type of user, as long as that user wants to pay as they go.
It also has a wide range of Pay Monthly plan durations, and it’s generally competitively priced.
With tethering allowed as well and 5G now available, Tesco Mobile is a strong network, but be aware that none of its plans let you roam beyond Europe for free and it lacks certain extras, such as VoLTE and Wi-Fi Calling. Still, it would make a good choice for most people.
