From all the options giffgaff have got available this December on SIM only, we think this £10 1‑month deal is their best. For your £10 a month, you get 15GB data alongside unlimited minutes and texts:

Even though it's in our pick of giffgaff's best SIM only deals, you can actually beat it on price with other providers, including ones that also use the O2 network. Here's where else you can get a lower price:

We also like their £12 for 20GB plan

To satisfy bigger data needs, another option for you on giffgaff, is their 1‑month SIM below, which costs £12 a month for 20GB data and comes with unlimited minutes and texts:

While this is a good enough deal to make it into the best of giffgaff'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, giffgaff 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 1‑month plan:

It's a good enough deal to get into giffgaff'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:

What we think about giffgaffRead our full review

As we show in our full review of giffgaff, we like that you get full access to O2’s network, including 5G, for a much lower price than being on O2 directly. You also get a decent free WiFi hotspot scheme.

giffgaff market their SIM only deals (their “goodybags”) as monthly bundles of minutes, texts and data with no contracts. Compare their plans here to find the best possible deal.

Their best value plans are their mid-range data deals. For these they work out as one of the cheapest providers on the O2 network (alongside Sky Mobile and Tesco Mobile).

giffgaff are pretty much a no-frills network. They do offer £5 free credit on your first £10 top up and if you get a friend to join giffgaff both you and your friend will get £5 free credit. They also offer inclusive EU roaming as standard.

Your giffgaff SIM will be delivered within 2 working days, and you can get it delivered to the EU within 3-5 working days or even to anywhere else in the world around 5+ days after ordering. They don’t offer eSIMs (see the networks that do).

It’s your right as a customer to get your SIM refunded within the first 14 days of receiving it. But you’ll only get back what you haven’t used, so if you used up a little bit of data you won’t get a full refund. Here’s how you do it.

Since you’re paying for your minutes, texts and data up front then you won’t have to pass a credit check for their SIM only plans. You’ll just have to give them some details so they know who you are.

If you want to switch to giffgaff from another network while keeping your old number you can do so by requesting a PAC from your old provider to give to giffgaff. You can read their instructions on how this works here.
