About

Who is giffgaff?

giffgaff is a UK Mobile Virtual Network Operator launched in November 2009 as an in-house challenger brand by O2 UK. It pioneered a community-led model where customers (“members”) earn payback by helping each other on the giffgaff community forum, instead of calling a traditional support line.

Since the 2021 merger of Liberty Global’s Virgin Media and Telefónica’s O2 into Virgin Media O2, giffgaff has been part of the same group, but it continues to operate independently with its own brand, pricing and online-only support.

giffgaff is regulated by Ofcom. Complaint handling falls under the Ombudsman Services: Communications alternative dispute resolution scheme.

4.4 / 5

~80,000 reviews

Positive overall

Exceptional for a UK telco. Customers consistently praise the goodybag flexibility, the SIM-only pricing and the community-led help model. The most common complaint: support is online-only with no phone number, so anything that needs a phone agent has to be resolved through the forum or the giffgaff app.

Which? annual survey

Top-rated customer score

Years running

Positive overall

Which? has placed giffgaff at or near the top of its UK mobile provider satisfaction survey for several years in a row, citing value, contract flexibility and ease of switching. Coverage scores match O2 (good in urban areas, mid-range rurally).

Ofcom complaints

Below threshold volume

Not separately listed

Mixed

giffgaff sits below Ofcom's reporting threshold and is not broken out in quarterly complaints data. Partly market share, but mostly because there is no contract: customers who are unhappy can leave instantly without an exit fee.

MoneySavingExpert forum

Strongly recommended forum sentiment

Hundreds of threads

Positive overall

A perennial UK MVNO favourite for cost-conscious users who want O2 coverage. Common watch-out: if you depend on phone-based support, giffgaff is not for you. Everything is community-led or via the app.

Selectra expert verdict

Independent read, no commission shaping

giffgaff is the easiest no-commitment recommendation we make. The £10 goodybag (25 GB, unlimited mins and texts, 5G) at 30-day rolling is the value sweet spot for most UK adults. Coverage is the O2 network at your postcode. Trustpilot at 4.4 / 5 is far above any major UK network.

The only honest catch is support: there is no phone number, no live chat with an agent, no shop. Everything runs through the giffgaff app or the member forum. If you are confident online, that’s a feature, not a bug, and the average response time on the forum is genuinely under 20 minutes. If you depend on speaking to an agent on the phone, go for Tesco Mobile or O2 direct instead.

FAQ

giffgaff goodybags, coverage and contact, your questions answered

Is giffgaff good in 2026?

Yes, for most people. giffgaff runs on the O2 4G and 5G network, so signal at your postcode is identical to a SIM bought from O2 direct. Goodybags start at £6 for 5 GB and unlimited UK texts, and there is no contract, no credit check and no exit fee. Trustpilot sits at 4.4 / 5 across 80,000 reviews, far above any major UK network. The honest weakness is support: there is no phone line, so all help comes through the giffgaff app or the community forum.

What network does giffgaff use?

giffgaff is a Mobile Virtual Network Operator (MVNO) on O2, which is owned by Virgin Media O2 (a Liberty Global and Telefónica joint venture). Coverage, speed and 5G availability are the same as on an O2-branded SIM at the same postcode. You can sanity-check at the O2 coverage checker before ordering a giffgaff SIM.

Does giffgaff include 5G and EU roaming?

Yes on both. 5G is included on every giffgaff goodybag from £6 upwards, at no extra cost, on any 5G-capable phone in a 5G-active O2 postcode. EU roaming is also included on most goodybags (free use in 36 European destinations, with a fair-use cap, in 2026). The £20 unlimited goodybag has unlimited EU data within fair use; smaller goodybags share the same allowance.

How much is giffgaff per month?

Current goodybag pricing (May 2026): £6 for 5 GB and 500 minutes; £10 for 25 GB unlimited mins and texts; £15 for 60 GB unlimited; £20 for unlimited data, mins and texts. All are 30-day rolling with no contract. Buy a different goodybag any time, including downgrading.

How do I contact giffgaff?

giffgaff has no phone line. All support runs through the giffgaff app (Help section) or the giffgaff community forum, where members and agents answer your post within minutes. For account, billing and SIM swap requests, sign in to My giffgaff from any browser.

How do I keep my number when leaving giffgaff?

Text PAC to 65075 from your giffgaff SIM. giffgaff replies within 60 seconds with a free Porting Authorisation Code valid for 30 days. Give it to your new UK network and your number transfers within one working day. There is no exit fee because there is no contract.
