Looking for a giffgaff referral code? When you order a free giffgaff SIM through a referral link and activate it, you get £5 in account credit. Join on an 18-month contract and you get an extra £10, bringing the total to £15.

This guide explains how giffgaff works, how to claim the referral reward, and whether it's the right mobile network for you.

What is giffgaff?

giffgaff is a UK mobile network running on the O2 (Telefonica) network. It's known for affordable, flexible plans called goodybags that you can change or cancel every 30 days.

Key details:

  • Plans from £8/month with data, unlimited calls, and unlimited texts
  • 30-day rolling goodybags — no contract required
  • 18-month contracts also available for lower monthly costs
  • uSwitch Network of the Year for 3 consecutive years
  • Community-driven support where members help each other

giffgaff's model is simple: reliable O2 coverage at lower prices, with the flexibility to change your plan whenever you want.

How does the giffgaff referral scheme work?

The referral reward has two tiers:

Tier 1: £5 for activating a SIM

  1. Click the referral link on this page to order a free SIM
  2. Wait for delivery (free, usually 1-3 days)
  3. Activate your SIM and choose a goodybag (minimum £8)
  4. Receive £5 credit in your giffgaff account

Tier 2: Extra £10 for an 18-month contract

If you join on an 18-month SIM-only or phone contract instead of a rolling goodybag, both you and the referrer receive an additional £10, making the total reward £15 each.

Keeping your phone number

You can bring your existing phone number to giffgaff:

  1. Text PAC to 65075 from your current phone
  2. You'll receive a PAC code by text within minutes
  3. Enter the PAC code when activating your giffgaff SIM
  4. Your number transfers within one working day

Your old contract ends automatically when the number transfers. You won't be double-billed.

giffgaff goodybags explained

A goodybag is giffgaff's term for a monthly plan. Here's what you get:

  • £8/month: 5GB data, unlimited calls and texts
  • £10/month: 20GB data, unlimited calls and texts
  • £12/month: 40GB data, unlimited calls and texts
  • £15/month: 100GB data, unlimited calls and texts
  • £25/month: Unlimited data, calls, and texts

All goodybags renew automatically but you can change or cancel before the next renewal. There are no exit fees on goodybags.

Is giffgaff any good?

giffgaff has been around since 2009 and has millions of UK customers. The O2 network provides 4G coverage to over 99% of the UK population, and 5G is available in selected areas.

The community support model works surprisingly well — most questions get answered within minutes by experienced members. If you prefer picking up the phone to speak to someone, this might not suit you, but for most issues the community forum and online help centre are more than adequate.

giffgaff's Trustpilot score of 4.1 reflects strong overall satisfaction, and the uSwitch award wins back up the value claim.

Should you join giffgaff?

If you want a reliable, affordable mobile plan without being tied down, giffgaff is hard to beat. The O2 network coverage is excellent, the prices are competitive, and the flexibility to change plan every month means you're never locked in.

The referral reward of up to £15 is modest compared to energy or banking referrals, but it's free money on a purchase you were making anyway.
