The Carphone Warehouse-owned iD network has let TechRadar into a little bit of a secret…there’s a fantastic SIM only deal that it doesn’t even promote on its own website.
Until the end of the year, you can get a 2.25GB SIM only plan for a mere fiver per month. If we’ve done our maths right (and that’s a big if), that’s 125% more data than you get with iD’s usual £5pm deal, which only yields a solitary 1GB of data.
When it comes to the best SIM only deals on the market at the moment, iD’s tariff is the best cheap plan going. But we know that 2.25GB just isn’t going to be quite enough data for everybody, so keep reading to see our pick of the other cheapest deals around.
This fiver a month SIM only deal in full:
iD | 30-day contract | 2.25GB data | 250 mins | 5000 texts | £5 per month
If you’ve not heard of iD before, it’s Carphone Warehouse’s very own network that piggybacks off of Three’s 4G coverage. It’s known for its super cheap prices – and this SIM only deal is no exception. iD has an even cheaper £3.99pm SIM as well, but you only get 500MB of data. So we much prefer this one.
Today’s other best SIM only deals:
Three | 12-month contract | 4GB data | Unlimited minutes and texts | £10 per month
As soon as you need more than a nominal amount of data, Three SIM only deals become the dominant force. 4GB for a tenner a month is exceptional value, and the only way that other networks get even close is if they start throwing cashback at you.
Vodafone | 12-month contract | 5GB data | 500 mins | Unlimited texts | £9 per month (after cashback)
Case in point! Vodafone is the next best network for price thanks the £54 cashback offer on this 5GB SIM provided by another Carphone Warehouse-owned retailer e2save. The headline price is great, but requires you to redeem the cashback in five chunks.
Three | 12-month contract | 30GB data | Unlimited minutes and texts | £18 per month
Three is so often the network that boasts the cheapest prices on the highest data – and SIM only contracts are no different. This tariff won the inaugural Best Phone Deal award at the Mobile Choice Consumer Awards 2017. Literally a prize winning deal!
