Tesco Mobile unlimited data SIM deals

Tesco Mobile is an MVNO (mobile virtual network operator) that’s partnered with O2, meaning that it has 4G and 5G coverage in the same places as O2.

But Tesco Mobile’s plans differ from O2’s, and so do the things you get with them. Though both networks sell unlimited data SIM Only plans – which in Tesco Mobile’s case are sold in 12 and 24-month durations and also come with unlimited minutes and texts.

Below, we’ve detailed everything else you can expect from an unlimited data SIM Only plan on Tesco Mobile.

Is roaming included?

Yes, Tesco Mobile lets you roam across 48 European destinations at no extra cost, and the network has less restrictive fair usage policies when roaming than most rivals too, as it simply states that you should use your phone more in the UK than abroad over a rolling four-month period.

Are there any speed restrictions?

No, Tesco Mobile’s plans won’t restrict your speeds, so you can make full use of 5G on the network.

Are there any fair usage restrictions?

Tesco Mobile doesn’t have any strict fair usage restrictions, simply stating that your usage of the network should “be for private, personal, and legitimate purposes only.” Some networks have hidden caps on their unlimited data plans, but there’s none of that here at the time of writing.

What other benefits are included?

Tesco Mobile’s SIM Only unlimited data plans also support tethering, Wi-Fi Calling, 4G Calling, and family plans. Plus, you can optionally convert your physical SIM card to an eSIM at any time, and if you’re a Tesco Clubcard member you sometimes have access to lower, frozen prices.

What other networks should you consider?

You might want to consider O2 instead of Tesco Mobile, since this network has the same coverage. Depending on your plan, it may also let you roam in more places at no extra cost, and it offers other benefits too, such as access to O2 Priority. However, as a major network, O2’s prices are sometimes higher.

Other options include Giffgaff and Sky Mobile, both of which also have the same coverage as Tesco Mobile.
