ASDA Mobile 5G Coverage

Last updated 4th February, 2026

Asda Mobile uses Vodafone’s network for 5G coverage, meaning its 5G service is available in parts of the same hundreds of UK towns and cities at the time of writing.

Asda Mobile launched its 5G service on March 30^th, 2021, and it was available in 100 UK locations immediately, as it benefitted from all the time Vodafone had already spent expanding its 5G coverage.

Below you’ll find full details of Asda Mobile’s 5G network, including the key places that it has 5G available in, the spectrum that it has access to, and how it compares to other networks.

Asda Mobile 5G Summary

To get a clearer idea of Asda Mobile’s 5G coverage in your area, just enter your postcode in our coverage checker at the top of this page.

That will then show you how much 5G, 4G, and voice coverage you can expect from Asda Mobile in the area, and it will also show how other networks compare.

We’ve aimed to make the most accurate and up to date coverage checker available, by using real-time data sourced both from the mobile networks themselves and independent sources, so you can rely on the information it provides.

How does Asda Mobile's 5G coverage compare to others?

We keep track of which networks offer 5G coverage across 120 major UK towns and cities, so you can see at a glance how they compare in key locations.

ASDA Mobile has the same number of 5G locations as Vodafone below:

It’s worth noting though that there won’t necessarily be 5G everywhere in these locations. A tick in the chart below just means that a network reports having some coverage there, so make sure to check the places that matter to you on a network’s official coverage checker or our coverage checker above to be sure whether you’ll get 5G.

The latest locations to get Asda Mobile 5G (via Vodafone and as of February 2026) include Canterbury, Chelmsford, Colchester, Crewe, Exeter, Ipswich, Peterborough, and Taunton.

4G coverage

While 5G coverage is still limited (but rapidly improving), Asda Mobile has widespread 4G coverage, which you’ll be able to make use of even on a 5G plan.

You can see an overview of its 4G coverage as well as that of other networks below.

How fast is Asda's 5G network?

Asda Mobile has said to expect 5G speeds of around 150Mbps, which largely lines up with the independent results we’ve seen for Vodafone’s network.

As while we don’t have any real-world data on Asda Mobile’s speeds yet, we do have some on Vodafone’s, which may well be similar, since they share infrastructure and spectrum.

According to Opensignal data from September 2024, then, Vodafone’s average 5G download speed is 138.7Mbps, which doesn’t compare brilliantly to Three but beats EE and O2.

Results are similar in a RootMetrics report from the first half of 2025, which recorded a median 5G download speed of 163.8Mbps. This report also found that Vodafone’s 95th percentile 5G download speed – which should be close to the max – was 500.8Mbps, and its 5th percentile one – which should be almost the slowest – was 13.7Mbps.

However, in older RootMetrics data from 2020, Vodafone had a top recorded 5G download speed of 545.6Mbps, which is one of the highest we’ve seen from the network.

Beyond that, there’s an Ookla report from the second half of 2025, in which Vodafone was found to have a median 5G download speed of 129.78Mbps and a 90th percentile 5G download speed of 364.30Mbps.

Latency

Asda Mobile hasn’t talked about its latency (the amount of time the network takes to respond to a data request on your phone), but based on 2023 data from Speedtest, Vodafone’s median 5G latency is 31ms - so Asda Mobile’s might be similar, since it uses Vodafone’s infrastructure.

In any case, it should be better than 4G latency, which averages around 30-50ms most of the time, and that’s a good thing, as a high latency can make the network feel slow, even with speedy data.

When looking at loaded latency (which means the latency when the connection is under heavy use), Ookla found in 2025 found Vodafone’s was 449.16ms, and while that might sound high it’s the second-best result in that test.

What frequencies/bands does Asda Mobile use?

Asda Mobile uses Vodafone’s 5G frequencies, which is what you can see in the table above.

As you can see then, it’s the 40GHz, 26GHz, 3.4Ghz and 3.6GHz ones that the network uses for 5G.

These are all higher frequencies than those the network uses for 4G, and that’s because higher frequency bands are available in greater capacity, which helps them deal with large numbers of users at the same time and larger data requirements – things that 5G networks are having to cope with.

The lower frequency spectrum though is better at travelling long distances, and at passing through walls. As such, both kinds can be important to a well-rounded network.

Vodafone – through its combined spectrum holdings with Three as part of the VodafoneThree merger – has 2,030MHz of 5G spectrum, with that total including some 700MHz spectrum held by Three, which isn’t mentioned in the Vodafone-only chart above.

It’s unclear whether Asda Mobile yet has access to this full combined holding or not, but it likely will sooner or later, and that’s good news, as EE and O2 each have less at 1,920MHz.

While these spectrum holdings probably won’t change for a while, they may eventually, with more 5G spectrum auctions potentially taking place in the future.
