Out of all the SIM only plans available this August on giffgaff, we'd say their best value deal is their 1‑month SIM below, which gets you 15GB data, plus unlimited minutes and texts for £10 a month:

It's not actually the cheapest SIM only deal on the market at the moment with 15GB data or more but it is the lowest-priced plan on any provider using the O2 network. See who's offering it for less here:

Their 20GB for £12 SIM is another good option

To get a bigger chunk of data, our next best pick of giffgaff SIM only plans is their 1‑month £12 deal below, which gets you 20GB data and 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 you can beat it on other networks:

giffgaff's 100GB for £20 plan is a good option too

If you need even more data, giffgaff are also offering this £20 SIM, which includes 100GB data, unlimited minutes and texts on a 1‑month plan. It's another of their best deals:

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 lower-priced networks' deals here:

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.
