We'd say the best SIM only plan giffgaff are selling this July is their 18‑month unlimited data deal below, which comes in at £25 a month and includes 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 a smaller amount of data, you might like the £12 SIM only deal running on giffgaff at the moment. It's a 1‑month plan, which comes with 26GB data, unlimited minutes and texts too:

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. See where you can get it for less here:

If you don't want so much data, 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 2GB data, unlimited minutes and texts for £6 a month:

In comparison to the rest of giffgaff's current SIM only plans, it's one of the best. But it is beatable on price, even if you're set on joining a provider that uses the O2 network. 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.
