Asda Mobile unlimited data SIMs

An Asda Mobile unlimited data SIM gives you genuinely unlimited 4G and 5G data on the Vodafone network, with no monthly cap to worry about.

A fair-use policy may apply to discourage commercial misuse, but for normal personal browsing, streaming and tethering you can use as much as you like.

Unlimited data suits heavy users who stream video and music, work on the go, or rely on their phone as a hotspot for other devices.

If you regularly use more than around 20GB a month, an unlimited plan removes the worry of running out, whereas lighter users may save money on a capped allowance.
