Asda Mobile SIM only deals: prices, networks, eSIM, and what they cost abroad

What Asda Mobile SIM only deals were listed on 10 November 2026?

Asda Mobile's SIM only page offered five data sizes on 12 and 24-month contracts when we read it, each with unlimited UK minutes and texts. The 24-month version is cheaper or the same:

The 25GB deals carried a £25 reward paid into your Asda Rewards Cashpot. Asda says its 12 and 24-month SIM only plans have no mid-contract price rises, and contract plans roll unused data over to the next month.

This is desk research from Asda Mobile's own pages. We have not bought or tested an Asda Mobile plan.

What are Asda Mobile's pay as you go plans?

Asda sells the same allowances as 1-month plans with no contract. On its pay as you go page these were Talk and Text for £4, 3GB for £5, 10GB for £8, 15GB for £10, 100GB for £18 and unlimited data for £22. The 1-month plans are flagged as including 5G. Asda's separate bundle list also showed some lower prices, such as £3.20, £6.40 and a 50GB bundle at £5, without saying which conditions applied, so we could not confirm who gets those.

On these figures, the 1-month plan costs the same as the 12-month contract for 10GB, 100GB and unlimited data. If you value the exit, the rolling plan costs you little.

Which network does Asda Mobile use?

Asda Mobile says customers "benefit from the Vodafone and Three networks", which it says reach 99 percent of the UK population. Our Vodafone UK and Three UK pages cover those networks' own plans.

Does Asda Mobile have eSIM?

Yes. Asda's eSIM page says you choose eSIM at checkout on a phone contract or SIM only deal, then get an email asking you to log in to your online account, where a QR code downloads the eSIM. Existing customers can switch a physical SIM to eSIM, or back, for free by contacting Asda. Asda says its eSIMs are for phones only and not currently compatible with tablets or wearables. The eSIM page does not mention the 1-month pay as you go plans, so check before ordering one as an eSIM. Asda also offers a free physical SIM by post.

Does Asda Mobile roaming work in Europe?

Yes, with a 5GB limit. Asda says its data plans include up to 5GB of EU roaming a month in 46 destinations, or your plan allowance if that's lower. After 5GB you pay 10p per MB, the same as its UK rate, and Asda says it texts you at 80 and 100 percent. You can also buy a roaming add-on in My Account, though the page did not list add-on prices.

The 46 destinations cover the EU, Norway, Iceland, Liechtenstein, Gibraltar, the Channel Islands, the Isle of Man, the Canary and Balearic Islands, Madeira, the Azores and the Åland Islands. Switzerland, Monaco and Turkey are not on the list Asda published.

You have to switch data roaming on in your Asda online account (under My Profile, then Features) as well as on your phone, and international calling needs turning on there too.

How much does Asda Mobile cost outside Europe?

Asda splits the rest of the world into three groups:

Asda's country search sorts each destination into a group, but the search tool didn't load for us, so we could not confirm which group Turkey, Japan or Thailand fall in.

Calling abroad from the UK is cheap: Asda listed 15p a minute to landlines and mobiles in the USA, Australia and New Zealand.

Is Asda Mobile any good for travel?

For Europe, yes, as long as 5GB a month covers you. A fortnight of maps, messages and some social media generally fits, and the 10p per MB charge after that is far lower than most networks' out-of-zone rates.

Who it suits: someone in the UK who wants a cheap contract without April rises, travels mainly to Spain, France, Italy or Greece, and doesn't need Switzerland. If you shop at Asda, the £25 Cashpot reward on the 25GB plans takes a little off the first year. If you split time between the UK and Switzerland, or travel beyond Europe often, look elsewhere.

Outside Europe it's expensive. 20p per MB in the United States works out at about £204.80 per gigabyte, so even 1GB on a short trip costs more than a year of the 3GB plan.

When is a travel eSIM cheaper than Asda Mobile roaming?

Anywhere outside the 46 destinations. Our verified prices, read on each seller's own site in August 2026, were $12.50 for Airalo's 5GB over 7 days in the USA, $13.99 for Saily's 5GB over 30 days and $16 for Nomad's 5GB over 30 days. In Turkey, Airalo's 5GB over 7 days was $9.

Inside Europe, if you need more than 5GB, an eSIM can also make sense. Our best eSIM for Europe guide compares regional plans, and the cheapest eSIM table ranks them by cost per gigabyte. Keep the Asda SIM on for calls and texts, with data roaming switched off; our data roaming guide shows how. For other UK networks, see the UK SIM card comparison.
