Superdrug Mobile
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. |

LycamobileLycamobile 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.

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:
