At present, Superdrug Mobile is our recommended provider if you’re looking for an unlimited data SIM card with no contract:
If you’re looking for unlimited data without the need for a contract, Superdrug Mobile is currently the best value provider.
With 99% population coverage from Three’s 3G & 4G network, Superdrug currently charges £20/month for their unlimited data plan. This is the joint cheapest plan, along with SMARTY’s unlimited data plan, but you’ll also get £20 back in Superdrug points when you sign up for Superdrug Mobile.
The £20 of Superdrug Health and Beautycard points essentially makes your first month free as you’ll get the £20 back to spend at Superdrug. This can either be in a Superdrug store, or it can be spent online on the Superdrug website (with free delivery when you spend £10 or more).
There are no fair usage limits or speed restrictions on Superdrug’s unlimited data plan and you can also cancel it whenever you like.

Lycamobile is a low-cost network, specialising in international phone calls. At present, they offer an unlimited data SIM card from £25 for 30 days of usage. This gives you unlimited UK minutes, unlimited UK texts and 99% 4G coverage from the O2 network. Customers ordering their Lycamobile bundle online will benefit from an introductory price of £19/month for the first 90 days.
As a cheaper alternative to fully unlimited data, there’s also a £20 Forever Data plan on Lycamobile. On this plan, 4G speeds are only available on the first 9GB per month. After the first 9GB per month, your download speeds are reduced to a maximum of 128kbps (around 0.1Mbps, which is roughly equivalent to the speed of a 2G connection).
On Lycamobile, the use of tethering and personal hotspot is not permitted.

In our opinion, the best value unlimited data plan without a contract in the UK is currently Superdrug Mobile’s £20 unlimited data SIM card. This gives you unlimited minutes, unlimited texts and unlimited data with 4G coverage from the Three network.
Behind the scenes, Superdrug Mobile is built on the SMARTY platform so the two networks share a lot of similarities in how they operate. There are, however, two main benefits to choosing Superdrug Mobile over SMARTY:

You can get an unlimited data SIM card with no contract on Three’s Pay As You Go service from £30/month. This gives you access to Three’s 5G network in 194 UK towns and cities, along with unlimited UK minutes and texts.
You should note that much cheaper unlimited data deals are available when you take a SIM-only plan on contract from Three. At present, Three offers unlimited data for just £16/month if you’re willing to sign up a contract. This is much cheaper than their unlimited data plan on Pay As You Go.
For more information, see our guide to unlimited data on Three.
On Vodafone, it’s possible to get an unlimited data SIM card for £40/month on Pay As You Go, without the need to sign a contract or to undergo a credit check. You’ll also get access to Vodafone’s 5G network included in the price.
This plan is shown in the following table:
Because of the incredibly high cost for unlimited data without a contract on Vodafone, we wouldn’t normally recommend this plan for most users. Instead, there are two alternatives that will give you much better value:
VOXI is a low-cost sub-brand of Vodafone, currently offering unlimited 5G data with no contract for £35/month.
VOXI’s unlimited data plan will give you access to Vodafone’s 5G network. This offers an average download speed of 150-200Mbps on 5G, with 5G coverage currently available in 100 UK towns and cities.
When using your mobile phone abroad in another European country, there’s a fair usage limit of 25GB per month on this plan.
For more information, you can read our in-depth VOXI review. Alternatively, if you’re looking for a lower-cost alternative to unlimited data, VOXI offers a range of plans with endless social media or endless video data.
