How Sky Mobile’s SIM only prices and benefits stack up
In our Sky Mobile review we rated them highly for giving you full access to O2’s excellent network for call signal and 5G coverage, while offering lots of nice benefits on top (see our O2 vs Sky Mobile review here).
Their SIM plans are all on 12-month contracts and they don’t offer unlimited data plans, so they don’t offer as much choice as some networks. But there’s still a wide range of plans (find their best deals here).
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 while also offering some great benefits that O2 don’t:
They offer an excellent unlimited free streaming data scheme on Sky TV apps and a great data rollover scheme that lets you keep data for 3 years. And you can gift data to other users on your account if need be.

What else you should know about Sky Mobile’s SIM only plans
You’ll get your SIM package within 1-3 working days of ordering. Your SIM package will come with each size of SIM to put into any phone. You can’t get an eSIM on Sky yet (these networks offer them).
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 want to switch from another network to Sky while keeping your number, you’ll have to request a PAC from your old network and send it to Sky. Here’s their full guide on how to do it.
