Updated May 14, 2026 · By Jules de Bruin · UK MVNO on the O2 network, sold direct online with member-run support.
Updated May 2026. giffgaff is a UK MVNO launched in 2009 that runs on the O2 UK 4G and 5G network and is wholly owned by Virgin Media O2. It sells 1-month rolling Goodybag plans from GBP 6 to GBP 20, with no contract, no credit check, and no annual price rise. Customer support is delivered primarily through a member-run community forum where users earn "payback" points for helping. EU roaming up to 5 GB is included on every paid Goodybag.
What is giffgaff?
giffgaff is a UK mobile virtual network operator (MVNO) launched in November 2009 by O2 UK and now wholly owned by Virgin Media O2 — the joint venture between Telefónica and Liberty Global. It runs entirely on the O2 UK 4G and 5G network and sells SIM-only plans direct to consumers through giffgaff.com, with no high-street stores and no traditional call centre.
The brand was designed from day one as a "mobile network run by you". Instead of a conventional support model, giffgaff routes the bulk of customer questions to a public community forum where other members answer. Forum contributors earn payback points twice a year, which can be paid out as cash, redeemed against the next Goodybag, or donated to charity. Paid agents handle complex billing, fraud, and number-porting cases, but the front line is the community.
giffgaff has no minimum-term contracts and runs no credit check at sign-up. SIMs are ordered free on the website (or activated as an eSIM), top-ups and Goodybags are purchased online, and the account is managed from the giffgaff app. The operator is regulated by Ofcom as a UK communications provider and inherits its underlying network performance — including 4G availability and 5G footprint — directly from O2.

What is a giffgaff Goodybag?
A Goodybag is giffgaff's branded name for a 1-month rolling pay-as-you-go bundle that combines minutes, texts, and a data allowance for a single up-front price. Goodybags auto-renew every 30 days unless cancelled in-app, and they can be swapped each month without penalty — making them functionally a SIM-only plan with monthly cancellation rights instead of a 12- or 24-month contract.
As of May 2026, the active Goodybag ladder runs from GBP 6 for 4 GB at the entry tier, through mid-range bundles around GBP 10 for 25 GB and GBP 12 for 80 GB, up to an Unlimited Goodybag at GBP 20 with unlimited data, calls, and texts. All paid Goodybags include unlimited UK minutes and texts and a portion of EU roaming data (up to 5 GB on the Unlimited tier, less on smaller bundles).
Three structural details set Goodybags apart from a standard UK contract:
- No annual price rise. giffgaff does not apply mid-contract CPI or RPI uplifts — the headline price is the price you pay until giffgaff publicly changes the tariff.
- Rollover-style flexibility. If you don't use a Goodybag's full allowance you can switch to a smaller bundle the next month with one tap, and there is no exit fee.
- Always SIM-only. giffgaff does not bundle handsets on monthly instalments the way EE or O2 do; phones are sold for cash or financed separately via partners.
Tethering is allowed on every Goodybag, and 5G access is included at no extra cost on compatible handsets in O2 5G coverage areas.

Frequently Asked Questions
Which network does giffgaff use? expand_more
giffgaff is a virtual operator that runs entirely on the O2 UK network, including O2's 4G and 5G coverage. Because giffgaff is owned by Virgin Media O2, it uses the same masts and core network as O2 itself, so real-world coverage matches O2's published map.
Is giffgaff a contract or pay-as-you-go? expand_more
giffgaff is pay-as-you-go. Each Goodybag is a 1-month rolling bundle that auto-renews until cancelled, with no fixed-term contract, no credit check, and no exit fee. You can change Goodybag size or stop entirely from one month to the next.
Does giffgaff work for EU roaming? expand_more
Yes. Paid Goodybags include EU roaming under a fair-use policy — up to 5 GB of data on the Unlimited Goodybag, with smaller caps on cheaper bundles, plus included minutes and texts. Roaming applies to EU-27 plus a list of selected destinations published on giffgaff.com.
Does giffgaff support eSIM? expand_more
Yes. giffgaff supports eSIM activation on most modern iPhones (XS and later) and a range of Android handsets. New customers can choose eSIM at sign-up, and existing physical-SIM customers can swap to eSIM for free from the giffgaff app.
Does giffgaff run a credit check? expand_more
No. Because Goodybags are prepaid in advance and there is no contractual debt to recover, giffgaff does not run a credit check for SIM-only sign-ups. A check may apply if you separately finance a handset through a partner lender.
