Running on O2’s network, Tesco Mobile offers 2G, 3G, 4G and 5G coverage in the UK. Tesco Mobile offers decent 4G coverage with over 99% population coverage and the network’s 5G coverage is live in 60 cities and towns in the UK at the moment.

In this review, we’ll have a look at Tesco Mobile’s network coverage in the UK and see what extra features you may or may not get if you choose to purchase a Tesco Mobile tariff.

Tesco Mobile 4G Coverage

Tesco Mobile uses O2 as its network provider and both carriers offer identical 4G network coverage, as well as identical download and upload speeds. According to Open Signal’s latest speed test results, O2’s, & therefore Tesco Mobile’s download speeds are around 18Mbps and upload speeds are around 6.4Mbps. Of course, the exact data speeds you get are dependent on your location.

Tesco Mobile’s network covers 99% of the UK’s population using 4G, and the network falls back to 3G and 2G for voice calls and texting when necessary. In terms of 4G network coverage and data speeds, EE is unrivalled. The network offers the fastest data speeds and the best network coverage by a long shot.

Tesco Mobile 5G Coverage

tesco-5g5G is the fifth generation technology standard for cellular networks and it’s the planned successor to 4G networks. It’s at least 10 times faster than 4G and offers much better latency.

Tesco Mobile’s 5G is available in 60 cities and towns and according to the network their average 5G download speed is in the region of 150Mbps to 200Mbps at the moment. However, Tesco Mobile 5G deals are exclusive to pay monthly deals, & PAYG customers don’t get to enjoy 5G data speeds.

Voice Call Quality

At Half Cooked we rely on network tests performed by independent testing bodies like umlaut, Open Signal and OOKLA. They perform the most extensive network tests and produce reliable, objective results. According to umlaut’s latest network tests O2 ranked in third place with a score of ‘satisfactory’, taking over Three, but behind EE and Vodafone.

Test results indicate that the call setup times of Tesco Mobile (O2) were considerably longer than most other networks, but the network seems to be improving at a faster rate than all the others.

4G Calling & Wi-Fi Calling

tesco-mobile-4g-wifi-callingBoth 4G Calling and Wi-Fi Calling eliminate blackspots where you can’t normally stay connected, get bad reception or get no phone signal at all. They also improve the quality of your voice calls significantly. 4G Calling uses your carrier’s 4G network and utilises it to deliver HD voice calls. With Wi-Fi calling you can make and receive calls by using an available Wi-Fi network.

Sadly, Tesco Mobile doesn’t offer these voice call features. Most MVNOs skip these features to offer competitive prices. You might want to check out Sky Mobile’s offers, as it’s also using O2’s infrastructure and offers both these perks.

Wi-Fi Hotspots

tesco-mobile-club-cardEven though O2 offers over 16,000 free Wi-Fi hotspots, Tesco Mobile doesn’t provide any free Wi-Fi hotspots to its customers. Free Wi-Fi helps you to save your precious mobile data, and given how Tesco Mobile doesn’t offer any unlimited data deals, we think the network’s customers could really benefit from this perk. On the other hand, if you’re a Tesco Clubcard Plus member, you get double data.

Tethering

Nowadays most mobile devices allow you to turn them into personal Wi-Fi hotspots. This is also known as tethering. When you’re tethering you share your data connection with other devices such as other smartphones, tablets and laptops etc.

Tesco Mobile allows you to tether at no extra cost on all their plans. You can even tether when you’re using their traditional PAYG service, however you’ll be charged Tesco Mobile’s standard rates.

We’d like to remind you that tethering eats up your data at a much faster rate and you might want to sign up for an unlimited data deal, if you plan to tether regularly. If you’re looking for a cheap deal with limitless data, SMARTY might be the best network for you. Make sure to read our SMARTY Review before you make your final decision though!

International Roaming

Tesco Mobile’s international roaming isn’t anything special. The network’s roaming scheme is called ‘Home From Home’ and it lets you take your minutes, texts and data with you to 48 destinations in Europe.
