Sky's best SIM only deals

We also like their £7 for 3GB plan

If that's more data than you need, another option for you on Sky, is their 12‑month SIM below, which costs £7 a month for 3GB data and comes with unlimited minutes and texts:

While this is a good enough deal to make it into the best of Sky's SIMs, you can beat it for price (even if you definitely want a provider that uses the O2 network). See who's offering it for less here:

Their 100GB for £20 SIM is another good option

If you think you'll need even more data, Sky have got a £20 deal on SIM only we think's worth looking at. It gets you 100GB data, unlimited minutes and texts and it's a 12‑month plan:

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. Here's where you can beat it on other networks:

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.
