Time and time again, Three has come up with unlimited data SIM only deals that leave the competition struggling to keep up. But now, Three is having a change of pace taking on the world of cheap SIM only deals.

Offering an impressive 8GB of data for just £9 a month, Three has catapulted itself to the top of the market's collection of cheap SIMs. Without dropping down to realms of 1-3GB of data, you will struggle to find an offer that is cheaper than this.

However, if you're looking at that offer and thinking 8GB of data just won't do it for you then don't worry. As we said above, Three has been showing us its unlimited data prowess for a while now, offering some of the best big data SIMOs too.

Cheap or big data - you can find both of Three's market leading offers down below. Or, if there is something these Three offers don't quite bring to the table for you, check out our guide to the best SIM only deals to see your other options.

Three | 12 months | 8GB data | Unlimited calls and texts | £9 per month
Costing just £9 a month, Three has taken the spot of the best price tag at this data point. You can go cheaper but that will mean a massive drop in data. In fact, without jumping up to the unlimited regions of data, this feels like the best value SIMO plan around right now, shooting past Vodafone's 8GB data SIM for £10 a month.
