We're starting to think Three might be getting a bit greedy. First, it took the number 1 spot in our SIM only deal guide with a brilliant unlimited data plan, then it followed straight up with a second unbeatable unlimited data offer, beating out all of the competition twice over.

However after a month or so of pure unlimited data domination, Three has now announced an end date for that second offer, setting a countdown for February 4. That means for anyone tempted by the idea of unlimited data for just £10 a month will have to act fast.

Of course, for anyone who hasn't already heard about this SIM only deal, £10 a month sounds too good to be true. That's because those costs last for 6 of the 24 months of the contract, going back up to £20 after that.

While this is obviously an exceptional offer and we'll be sad to see it go, it's not all doom and gloom. No end date has yet to be set for Three's unlimited for £18 a month offer, which for some will actually be the better of the two.

Three's half price SIM only deal promotion:

SIM only from Three | 24 months | Unlimited data, calls, and texts | £10 a month for the first six, then £20 a month
Getting unlimited data for just £10 is a rare sight and one that only Three has managed to achieve so far. Of course, those bills only last for six months and then you'll have to pay £20 a month for the last 18, which is still one of the best prices around. The only issue is that it lasts for 24 months. Too long? Try the offer below.View Deal

Three's £18 a month unlimited SIMO:

SIM only from Three | 12 months | Unlimited data | Unlimited calls and texts | £18 a month
24 months too long for you? Or would you rather keep your bills constant throughout? Either way, this offer is an excellent alternative to what you can get above. Yes, it's not half price but it is still exceptional, topping everything else on the market.View Deal
