More often than not, if you can afford it, it’s cheaper to buy a smartphone outright SIM free, then opt for a SIM only deal to take care of your minutes, texts and all-important data.

The total cost of ownership (TCO) over 24 months – the typical contract length – is often much lower going this route than taking out a contract.

If you are currently searching for a SIM only deal, it pays to shop around to make those savings go even further as there’s a lot of competition from the various network operators.

Then there are also the MVNOs (mobile virtual network operator) like Virgin Media who piggyback on the bigger networks for their coverage at very competitive prices.

Right now, Vodafone is offering an excellent SIM only offer as part of its Vodafone Basics plan. These prices will only last until May 2nd 2018, so you better act fast if you don’t want to miss out.

Vodafone is offering:

These SIM only contracts are only 12 months, too, so you won’t be locked into a long contract. The inclusion of unlimited calls and texts are a real bonus, and you get a generous amount of data on both packages for light users. Caps are in place to make sure you don’t go over your limit to avoid overspending, which should take some weight off your mind.

iD Mobile is currently offering 50% extra data for its £5 per month package. This gets you 1.5GB (instead of 1GB), 250 minutes and 5000 texts a month.

Best SIM only deals – Virgin Media

If you’re in need of considerably more data, Virgin Media is having a flash sale that means you can get 100GB of data for just £20 a month. That’s an incredible amount of data for a very wallet-friendly price for anyone who needs lots and lots of data.

Virgin Media is an MVNO that uses EE’s network, so there’s no worries about reception. This also gets you 5000 minutes and unlimited texts. Be sure to act fast, however, as this deal expires on April 23rd.

This is actually a PAYG SIM, meaning you’re not tied into a contract – you just need to top up enough to qualify for the data.

Right now, for the first month, O2 is tripling the data you get for your money. That means you could get up to a whopping 60GB of data for your first month.

If you know you’re going to need a lot of data for a one-off period, tactically opting for one of these PAYG SIMs could be a great idea.
