We've seen it chop and change, come and go, but one thing we do know - Three's unlimited data SIM only deal is the gift that (for now) won't stop giving. And until it finally bites the bust, remains the best SIM only deal currently on the market.

Let us refresh you on the details of this stand-out SIMO. Firstly and most obviously, you're getting unlimited data. But where this deal gets interesting is the pricing.

To secure this big data cap, you only need to pay £20 a month, making it the cheapest price around. However, Three then decided to show off its price-chopping prowess even more, offering a promotion allowing you to halve your bills down to £10 for the first six months of your contract. That's an instant £60 saving!

Three even has those who need a shorter contract sorted. For those who can't commit to a full two year contract, Three can also offer a 12 month unlimited data SIMO for just £20 a month, just without that reduced price for the first six.

With no confirmed end date in sight, now is the time to reap the benefits of Three and its impressive offers before it finally brings it to a close. You can see all of the details down below. Or head over to our SIM only deals guide to see everything else on the market. 

Three's best SIM only deal bargains:

Three | 24 months | All-you-can-eat data | Unlimited calls and texts | £20 per month, and £10 per month for the first 6 months
This offer is really quite simple. For the first six months of your contract you pay £10, for the next 18 you pay £20. That makes this the best SIM only deal around by quite a stretch. And if you don't like the idea of being tied in for that long, Three can also offer a 12 month unlimited data offer for just £20 a month.
