Looking at all giffgaff's options on SIM only this March, the deal that jumps out to us is their unlimited data for £25 one below. It's a 18‑month plan and comes with unlimited minutes and texts too:

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). Here's which other networks can beat it:

For those with smaller data needs, we'd say this is one of giffgaff's best deals on SIM only this month too. It's a 1‑month plan, comes with 26GB data, unlimited minutes and texts for £12 a month:

It's actually possible to beat this deal if you're not fussed whether your SIM is with a provider using the O2 network. But if you are, it is the current best-priced option. See where you can get it for less here:

If that's more data than you need, have a look at giffgaff's 2GB SIM below at £6 a month, as it's another good deal. It's on a 1‑month plan and comes with 2GB data, unlimited minutes and texts:

It might not be the lowest-cost SIM only deal with 2GB data or more on the entire market but if you're sure you need a SIM using the O2 network, it is the best-priced. Here are the networks offering it cheaper:

In our full review of giffgaff we said we like that they offer full access to O2’s 5G/4G/3G/2G network at much lower costs than joining O2 directly. They also have a nice free WiFi hotspot scheme on top of that.

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.

giffgaff still offer inclusive EU roaming on all plans at no extra cost. And you can get £5 free credit on your first £10 top up or bring a friend onto giffgaff to both get £5 free credit.

You’ll receive your SIM package within 2 working days. And you can even have it delivered in the EU within 3-5 days and beyond the EU around 5+ days after you order. giffgaff don’t offer eSIMs (these networks do).

If you’re not happy with your SIM you can return it to get a refund within 14 days. But you only get a refund on what you haven’t used, so you won’t get a full refund if you used some data (read more here).

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’ll have to request a PAC from your old provider to give to giffgaff. You can read their instructions on how this works here.
