Out of all the SIM only plans available this July on giffgaff, we'd say their best value deal is their 1‑month SIM below, which gets you 25GB data, plus unlimited minutes and texts for £15 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 other networks you can beat it on:

Or their £12 for 12GB SIM plan is worth a look too

If you need less data, you might like the £12 SIM only deal running on giffgaff at the moment. It's a 1‑month plan, which comes with 12GB data, unlimited minutes and texts too:

It does enough to get into our pick of giffgaff's best SIMs but that doesn't mean it's unbeatable on price. Other providers (even ones that use the O2 network) can beat it. See the networks with cheaper plans here:
