What is Asda Mobile?

Asda Mobile is the mobile brand of Asda, the UK supermarket chain. It operates as a mobile virtual network operator (MVNO) and, since 2021, runs on Vodafone’s national 4G and 5G network. Prior to the switch it used EE infrastructure, but the move to Vodafone aligned Asda Mobile with a strong 5G rollout and gave it the ability to offer 5G to customers at no extra cost.

Asda Mobile focuses on SIM-only bundles — there are no handset subsidies or lengthy contracts. Plans are 30-day rolling, meaning you can change or cancel each month without penalty. This simplicity, combined with supermarket-brand pricing, makes Asda Mobile a popular pick for value-conscious consumers and those who want a reliable 5G connection without a credit check.
