We think Sky Mobile's best value option on SIM only this September is their £16 a month plan below, which comes with 75GB data, plus unlimited minutes and texts on a 12‑month deal:
Unlimited minutes + Unlimited texts + 25GB 75GB data (5G) = £16 a month (12‑month contract)

This isn't the very cheapest deal with 75GB data or more out now. But if you definitely need a SIM only plan that uses the O2 network, we think it is the best option. See the networks that beat it here:
Unlimited minutes + Unlimited texts + 80GB data (5G) = £5 a month for 6 months, then £10 (24‑month contract)

For people who don't need that much data, you might like the £14 SIM only deal running on Sky Mobile at the moment. It's a 12‑month plan, which comes with 45GB data, unlimited minutes and texts too:
Unlimited minutes + Unlimited texts + 15GB 45GB data (5G) = £14 a month (12‑month contract)

While it's good enough to be in our pick of Sky's best SIM only deals, other providers do still have similar plans for less, even ones that also use the O2 network. Here are the networks where it'd cost less:

Their 5GB for £8 SIM is another good option
just
£8
a month
✔ Unlimited mins and 5GB data See full deal

(opens in new window)
If that'd be too much data for you, we'd say this is one of Sky's best deals on SIM only this month too. It's a 12‑month plan, comes with 5GB data, unlimited minutes and texts for £8 a month:
Unlimited minutes + Unlimited texts + 5GB data (5G) = £8 a month (12‑month contract)

It's definitely one of Sky's best. But it's not market-leading. You can get a similar plan on other providers for less, even if you need your SIM to use the O2 network. See which networks that are cheaper here:

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.
