Looking at all giffgaff's options on SIM only this January, the deal that jumps out to us is their 25GB for £15 one below. It's a 1‑month plan and comes with unlimited minutes and texts too:

It's a good deal by giffgaff's standards but price-wise you can still beat this plan on other providers (even ones that still use the O2 network). Here are the networks offering it cheaper:

They're also offering 20GB for £12 on SIM only currently
