Pros & cons

Pros

  • Very affordable plans starting from just five pounds per month with unlimited calls and texts
  • 5G access included at no extra cost on all data plans across 100 UK towns and cities
  • Data rollover on pay monthly plans means unused data carries over to the following month
  • Wi-Fi calling available for improved indoor coverage at no extra charge

Cons

  • SIM-only contracts are now 12 or 24 months - the 30-day rolling monthly option was withdrawn in 2025 and survives only on pay as you go
  • Data rollover is limited to the 12 and 24 month contract plans, not the cheaper 1-month pay as you go tiers
  • The four pound Talk and Text entry plan carries no data at all, so 5G only starts from the five pound tier

Asda Mobile Overview

Asda Mobile is a budget MVNO operated by the supermarket chain Asda, running on Vodafone's network. The service has been through several network changes over the years, originally launching on Vodafone, moving to EE, and then returning to Vodafone in early 2021. Today, Asda Mobile offers a simple, no-fuss range of SIM-only plans on rolling 30-day contracts, designed for customers who want reliable mobile service without the complexity or cost of a traditional contract.

Asda Mobile focuses squarely on simplicity and value. All plans include unlimited calls and texts, with data allowances starting at 3GB and going up to unlimited. The network includes 5G access at no extra cost in over 100 UK towns and cities, data rollover on pay monthly plans so unused data carries over to the next month, and Wi-Fi calling for improved indoor coverage. Plans start from just four pounds per month, making it one of the most affordable options in the UK market.

While Asda Mobile does not offer handset contracts or eSIM support, its straightforward approach appeals to users who simply want a working SIM card at a low price. The Vodafone network provides solid coverage across the UK, and the inclusion of EU roaming on all plans adds extra value for occasional travellers. Asda Mobile consistently ranks in the middle of customer satisfaction surveys, offering a reliable if unspectacular service.

Coverage & Speed

Asda Mobile benefits from Vodafone's extensive network, which covers over 99% of the UK population with 4G. 5G coverage is available in more than 100 towns and cities and continues to expand. The network provides reliable service in most urban and suburban areas, though coverage in very rural or remote locations can be less consistent than on EE's network.

Plans & Pricing

Asda Mobile sells SIM-only plans on 12 and 24 month contracts alongside 1-month pay as you go bundles; the rolling 30-day monthly contract was withdrawn in 2025. Every plan except the four pound Talk and Text tier includes 5G access, Wi-Fi calling and EU roaming in 46 destinations, and all include unlimited UK calls and texts. Data rollover applies to the 12 and 24 month contract plans.

Roaming

Asda Mobile includes EU roaming on all plans at no extra cost, allowing customers to use their UK minutes, texts, and data allowances while travelling in European destinations. A fair use policy applies to data usage while roaming. The network automatically enables roaming on your phone, and you will receive a text notification with pricing information when you arrive in a new country. Roaming outside the EU is available but will incur additional charges.

Our Verdict

Asda Mobile delivers on its promise of simple, affordable mobile service. The combination of low prices, Vodafone's reliable network, 5G access, and useful features like data rollover and Wi-Fi calling makes it a solid choice for users who do not need the latest bells and whistles. The tiered unlimited data plans are a particularly smart offering, allowing customers to choose the speed tier that matches their needs and budget.

The main limitations are the lack of eSIM support, the absence of handset contracts, and the restricted customer service hours. If you need an eSIM or want to spread the cost of a new phone over a contract, you will need to look elsewhere. The Monday-to-Friday customer support hours may also frustrate users who need help at weekends.

Overall, Asda Mobile is a dependable budget option that gets the basics right. It will not win any awards for innovation, but if you want a cheap SIM that just works, with the added benefits of data rollover and 5G on a pay-as-you-go-style rolling contract, Asda Mobile is worth considering. Its Which? customer score of 77% places it solidly in the middle of UK mobile providers, reflecting a service that is reliable without being exceptional.
