We think Sky Mobile's best value option on SIM only this May is their £6 a month plan below, which comes with 2GB data, plus unlimited minutes and texts on a 12‑month deal:

You can beat it for price if you don't need your SIM to be with a provider using the O2 network. But if that's a must, then it is the lowest-cost SIM with 2GB data or more. See the networks with cheaper plans here:

Sky's 3GB for £7 plan is a good option too

If you need more data, the next best SIM only plan on Sky Mobile in our opinion is their 12‑month one below. For £7 a month, you get 3GB data, plus unlimited minutes and texts:

It's currently the best priced 3GB data or more SIM only deal on a provider using the O2 network, even if you can beat it on price if you're open to ones not on O2. Here's which other networks can beat it:

Their £15 for 50GB plan is a decent deal for May

For even more monthly data, another good deal on Sky Mobile at the moment is their £15 SIM only plan here, which includes 50GB data instead, plus unlimited minutes and texts:

It's a good enough deal to get into Sky's best SIMs but you can actually get a lower price for a similar plan elsewhere, even if you definitely want it to use the O2 network. See where you can get it for less here:

We rate Sky Mobile highly in our review of them for giving you full access to O2’s brilliant call signal and decent 5G network coverage, as well as offering lots of benefits on top of that (see our O2 vs Sky Mobile guide here).

They only offer 12-month SIM only contracts, so there’s not a whole lot of flexibility there. Also they don’t offer unlimited data plans. But there’s still a decent range of data options. Check here to see their best current deals.

Sky’s best value deals tend to be their mid-range data deals. They’re a cheaper way of getting onto the O2 network than going with O2 directly, but aren’t the cheapest (giffgaff and Tesco Mobile tend to work out cheaper).

They offer some of our favourite benefits, such as a brilliant unlimited free streaming data scheme on Sky TV apps and a great data rollover scheme that lets you keep data for 3 years.

Your SIM will be delivered within 1-3 working days. The package you receive will contain each size of SIM card to pop into any phone. Sky don’t yet offer eSIMs (see the networks that do here).

Once your SIM card arrives, you have 14 days to cancel your SIM to get a full refund if you’re not happy with it. Here are the full details on how to do that.

To get on a Sky Mobile SIM only contract you’ll have to pass a credit check. There’s no way to pay as you go or buy a monthly bundle to avoid this.

If you’re switching from another network to Sky and you want to keep your number then you’ll have to request a PAC from your old provider and give it to Sky when you want to switch. Here’s more info on how to do that.
