Sky's 2GB for £6 plan is a good option too

If you need less data, we also think this £6 Sky Mobile SIM is one of their best options. It comes with 2GB data, unlimited minutes and texts on a 12‑month deal:

There are other networks charging less for a SIM with 2GB data or more but this is the best current option with a provider that uses O2. See where you can get it for less here:

Their £9 for 7GB plan is a decent deal for August

To get more data, Sky's £9 SIM below is another of their best deals this month. For £9 a month, it offers 7GB data, unlimited minutes and texts on a 12‑month plan:

It can actually be beaten on price if you don't need your SIM to be with a provider that uses the O2. If you do need that, it is the cheapest SIM with 7GB data or more. Here are the networks offering it cheaper:

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.
