Why we love: giffgaff

I changed to giffgaff about a year ago, when I was given a hand-me-down phone and was looking for a good data-based SIM-only deal. I ordered the SIM online, chose my monthly rolling plan and haven’t looked back since.

There’s so many incentives to sign up to giffgaff - you can get a free SIM card, £5 credit with friend referrals, and exclusive student offers. But it’s not all about the incentives. They have great coverage too. If you’re unsure about your area, all you have to do is go on the website and type your postcode to check the coverage.

I’m an advocate for buying expensive tech second hand, and giffgaff offer a great range of refurbished phones that come with a 12-month battery and at least 80% battery life. Plus, if you have an old phone you’d like to sell, then you can recycle with them too. Just enter in your unique IMEI on their website to see how much your gadget is worth.

At VoucherCodes, we’ve been working with giffgaff since 2011, so the partnership is well established. Our customers spend an average of £83 per transaction and save £14.50. What’s more, all our giffgaff promo codes and hand-tested too, so you can trust them to work at checkout.
