Asda Mobile Review (November 2026): Plans From £5, Is It Any Good?

Is Asda Mobile any good? Yes, if you want a supermarket SIM powered by Vodafone, with plans from £5 a month for 3GB and 10GB for £7 a month on a 24-month contract, as of 11 November 2026. Unlimited data is £19 a month for 24 months, only £2 more than the 100GB 24-month plan at £17, and those 12- and 24-month contracts come with no mid-contract price rises, unused-data rollover, and roaming in 46 European destinations.

Last updated: 11 November 2026. Plan prices, Rewards terms and roaming allowances are from mobile.asda.com on 11 November 2026. Asda Mobile’s site says customers benefit from the Vodafone and Three networks, covering 99% of the UK population; confirm the signal at your address on Ofcom’s mobile coverage checker. The Which? customer score is from its January 2026 survey of 5,137 mobile customers.

Who Asda Mobile suits, and who should look elsewhere

Asda Mobile suits you if Vodafone coverage is strong at home and work, you already shop at Asda, and you want a simple SIM with a locked monthly price on 12 or 24 months. The 10GB plan at £7 a month is the everyday pick in this review. If you use a lot of data, the 100GB plan at £17 and unlimited at £19, both on 24 months, sit only £2 a month apart, so the unlimited tariff is the straightforward choice once 100GB feels tight.

Look elsewhere if Ofcom’s checker shows a clearly stronger signal on O2 or Three at your address, or if you want a short rolling plan with a bigger allowance than Asda’s one-month range. Tesco Mobile is the other big supermarket brand, but it uses O2 rather than Vodafone, so the right starting point is coverage, not the shop you prefer. Our Tesco Mobile review and SIM only deals hub are the places to compare those alternatives.

Asda Mobile prices in November 2026

As of 11 November 2026, every SIM-only plan below includes unlimited UK minutes and texts. One-month plans have no long-term contract. The 12- and 24-month contracts add no mid-contract price rises and unused-data rollover. There is no 50GB plan on Asda’s own plans pages on this date.

Asda also lists a talk-and-text plan at £4 a month with no data. Prices can change, so confirm the figure in the Asda Mobile basket. For the wider market, see our SIM only deals hub.

Which network does Asda Mobile use?

Asda Mobile is powered by Vodafone. Ofcom’s Map Your Mobile tool lists Asda Mobile under the Vodafone network, alongside Lebara, talkmobile and VOXI, and Asda’s own site also says customers benefit from the Vodafone and Three networks, covering 99% of the UK population. A national population figure is not the same as a strong indoor signal in your kitchen, so use Ofcom’s coverage checker for your exact address and treat a retailer map as a second opinion.

Which?’s January 2026 survey of 5,137 mobile customers gave Asda Mobile a 77% customer score, 8th out of 15 providers. That is a solid mid-table result for a supermarket brand, not a reason to skip a postcode check. Network speed reports measure the host networks; your experience still depends on your handset, walls, network load and local masts. Our Vodafone review sets out how the host network itself compares on coverage and complaints.

Asda Rewards, roaming and the small print

The Rewards perk that actually appears on Asda’s plan cards on 11 November 2026 is a £25 Cashpot on the 25GB 12-month and 24-month plans. Asda says you receive £25 in your Asda Rewards Cashpot after two bill payments, paid within 30 days of the second payment, and that this offer ends on 12 January 2027. It only helps if you already shop at Asda and will spend the Cashpot. Do not treat it as a pure telecoms discount, and do not assume the same £25 sits on the 10GB, 100GB or unlimited plans, because those cards do not show it on this date.

Roaming is included in 46 European destinations, but the cap depends on the plan. The 3GB tariffs include 3GB of roaming. The 10GB, 25GB, 100GB and unlimited plans in this review include up to 5GB of your allowance abroad at no extra cost. After that, Asda’s roaming rates apply, and some nearby countries you might expect to be included, such as Switzerland, may not be. Read the destination list before you travel.

Unused data on the 12- and 24-month contracts rolls into the next month. 5G is included where the host network provides it and your handset supports it. Asda’s 12- and 24-month plan listing also describes the range as having no credit checks; the order journey is still the place to confirm that for the exact tariff you want. Support pages cover Wi-Fi calling and visual voicemail, which matter more if indoor signal is patchy.

Asda Mobile vs SMARTY, giffgaff and Tesco Mobile

This review’s three deal buttons go to Asda Mobile plans, not to rivals. Compare the cash over the full term, not only the first month, and only after you have run Ofcom’s checker for Vodafone, Three and O2. If Three coverage is the better fit, start with SMARTY. If O2 is the better fit, start with giffgaff or Tesco Mobile rather than assuming a supermarket brand will behave the same on every network. Our Three review is useful context if you are choosing a host network first.

How to switch to Asda Mobile and keep your number

Ask your current provider for a PAC if you want to keep your number, or a STAC if you are happy to move and take a new number. Give that code to Asda Mobile when you order. Most UK switches complete in one working day once the code is accepted. Keep your old SIM active until the new one connects, so you do not lose service mid-port.

Order from mobile.asda.com, or ask in store if you would rather collect a SIM. Before you pay, confirm the monthly price, the term, the roaming cap for that tariff, and whether any Cashpot applies. If you are leaving a 12- or 24-month contract elsewhere, check any exit fee first so the 24-month Asda saving still makes sense.

Pros and cons

• Pros: Vodafone-powered coverage from a familiar supermarket brand; 10GB for £7 or unlimited for £19 on 24 months, as of 11 November 2026; no mid-contract price rises on 12- and 24-month contracts; unused-data rollover; EU roaming included, with a cap; a dated £25 Cashpot on the 25GB plans if you shop at Asda.

• Cons: 24-month deals lock you in; roaming is capped at 3GB or 5GB depending on the plan; the Cashpot is not on every tariff; a national 99% coverage claim still needs a postcode check; it is not automatically the cheapest SIM once you compare the same allowance on Three or O2.

Important conditions

• Prices, roaming caps and Rewards terms are from mobile.asda.com on 11 November 2026 and can change.

• Asda Mobile is powered by Vodafone; Asda also says customers benefit from Vodafone and Three coverage reaching 99% of the UK population. Use Ofcom’s checker for your postcode.

• The £25 Asda Rewards Cashpot applies to the 25GB 12-month and 24-month plans, after two bill payments, and the offer ends on 12 January 2027.

• 12- and 24-month contracts have no mid-contract price rises, but leaving early can still mean an exit fee for the remainder of the term.

• Which?’s 77% customer score comes from its January 2026 survey and is not a guarantee of service at your address.

FAQ

What network is Asda Mobile on?

Asda Mobile is powered by Vodafone, and Ofcom’s Map Your Mobile tool lists it under that network, alongside Lebara, talkmobile and VOXI. Asda’s own site also says customers benefit from the Vodafone and Three networks, covering 99% of the UK population. That is a national headline, so confirm outdoor and indoor predictions for your address on Ofcom’s mobile coverage checker before you switch.

Is Asda Mobile any good?

Yes, if Vodafone coverage works for you and you want a straightforward supermarket SIM. Plans start at £5 a month for 3GB, with 10GB at £7 and unlimited at £19 on 24-month contracts as of 11 November 2026. Which?’s January 2026 survey gave Asda Mobile a 77% customer score, 8th out of 15, which is respectable, but it is not a substitute for a postcode check.

How much are Asda Mobile SIM plans in November 2026?

As of 11 November 2026, 3GB is £5 a month on one, 12 or 24 months, 10GB is £7 a month on 24 months, 100GB is £17 a month on 24 months, and unlimited is £19 a month on 24 months. All of those include unlimited UK calls and texts. Shorter 10GB, 100GB and unlimited terms cost a little more each month, and the 25GB plans are £14 or £13 with a £25 Cashpot.

Does Asda Mobile have mid-contract price rises?

Not on the 12- and 24-month SIM-only contracts in this review. Asda’s plan cards on 11 November 2026 say the monthly price stays the same for the length of the contract. One-month plans can be changed or left at the end of the month, which is the flexible way to avoid a long tie-in if you think prices might move.

What Asda Rewards do I get with an Asda Mobile plan?

On 11 November 2026, the 25GB 12-month and 24-month plans include £25 back in your Asda Rewards Cashpot after two bill payments, paid within 30 days of the second payment. Asda says that offer ends on 12 January 2027. The 10GB, 100GB and unlimited plan cards do not show that Cashpot on this date, so only count it if the basket still lists it for the tariff you want.

Does Asda Mobile include EU roaming?

Yes. Asda includes roaming in 46 European destinations, with a cap that depends on the plan. The 3GB tariffs include 3GB of roaming, while the 10GB, 25GB, 100GB and unlimited plans in this review include up to 5GB of your allowance at no extra cost. Read the destination list before you travel, because nearby countries are not all included, and out-of-allowance roaming is charged.

Can I keep my number when I switch to Asda Mobile?

Yes. Request a PAC from your current provider and give it to Asda Mobile when you order. Most UK ports complete in one working day once the code is accepted. Keep your old SIM active until the new one connects so you do not lose service mid-switch.

Is Asda Mobile cheaper than SMARTY or giffgaff?

It depends on the allowance, the term and the price in each basket on the day, and on which host network actually covers you. Asda Mobile is powered by Vodafone, SMARTY uses Three, and giffgaff uses O2, so compare like-for-like data only after you have compared all three on Ofcom’s coverage checker. A lower monthly price is a poor win if the signal is weak at home.

Final decision

Choose Asda Mobile if Vodafone coverage fits and you want a supermarket SIM with a locked 12- or 24-month price. The 10GB 24-month plan at £7 a month is the value starting point in this review; the 100GB plan at £17 and unlimited at £19 are the step-up options, only £2 a month apart. Pick a rival on Three or O2 instead if Ofcom’s map is clearly better there, or if you do not want a 24-month tie-in.
