Is giffgaff worth it? An honest review after 15 years

Affiliate disclosure: this post contains a giffgaff referral link. If you use it, you get £5 in account credit when you activate a SIM with a goodybag. I also receive credit. It doesn't change the price you pay.

I signed up to giffgaff in 2011. Fifteen years later, it's still on my list of recommendations for anyone who asks what mobile network they should be on. That kind of longevity says something: I've switched banks, switched energy suppliers, switched broadband twice, but I've never seriously considered leaving giffgaff.

The honest reason isn't that giffgaff is exciting. It isn't. There are no flashy perks, no unlimited social media data, no high-value referral vouchers. What giffgaff does is provide a reliable, cheap mobile plan on a major network with no contract, no fuss, and no nasty surprises. After 15 years, that's enough.

Three things I'd tell you up front

1. giffgaff is the best budget network for most people. Plans start at £8/month, run on O2's full network, and you can change or cancel every 30 days. If your primary concern is getting a reliable, cheap phone plan, giffgaff is the answer for the vast majority of UK users.
2. The community support model works better than you'd expect. giffgaff saves money by having its members help each other in online forums instead of running traditional call centres. It sounds like a cost-cutting exercise, and it is, but the result is a Trustpilot score of 3.9/5 and three consecutive uSwitch Network of the Year awards. The community is genuinely knowledgeable and fast.
3. The main thing giffgaff doesn't have is unlimited social media data. If you spend most of your data on Instagram, TikTok, and YouTube, VOXI's unlimited social media perk could save you money even though VOXI's monthly prices are higher. For everyone else, giffgaff's lower prices win.

What is giffgaff?

giffgaff is a mobile virtual network operator (MVNO) that runs on the O2 (Telefonica) network. It launched in 2009 with a simple proposition: cheap plans, no contracts, and a community-driven approach to customer support.

Key facts:

• O2 network with 99%+ UK population coverage on 4G
• 30-day rolling plans called "goodybags": no commitment, change anytime
• 18-month contracts also available for lower monthly prices
• No credit check for rolling goodybags
• Trustpilot 3.9/5 from hundreds of thousands of reviews
• uSwitch Network of the Year for 3 consecutive years
• Community support model: members help members in forums

giffgaff plans and pricing

giffgaff sells two parallel ranges: 30-day rolling goodybags (no commitment, change anytime) and 18-month contracts (cheaper per GB at the higher tiers).

The "/ X" entries reflect that for the same monthly price, an 18-month contract gets you a larger data allowance: the £25/month tier, for example, is 200GB rolling but Unlimited on contract. All plans include unlimited UK calls and texts and 5G access at no extra cost.

giffgaff is also currently running a promotional "extra data" boost on the mid-tier rolling plans (e.g. the £15 tier shows as 50GB base + 100GB extra = 150GB advertised), which cycles in and out.

The pricing advantage: giffgaff is cheaper than VOXI, Smarty and most other MVNOs at the lower-to-mid tiers. At Unlimited, the rolling prices are roughly level with VOXI; the 18-month contract is what unlocks giffgaff's biggest savings versus the competition.

The O2 network

giffgaff uses O2's full infrastructure:

• 4G coverage: 99%+ UK population
• 5G coverage: available and expanding across major cities
• Indoor coverage: comparable to other major networks in urban areas

In 15 years I've had signal issues in exactly the places you'd expect: rural Scotland, underground car parks, the odd dead spot in a concrete building. The same places every network struggles. Day-to-day in any town or city, the O2 network is reliable and fast enough for everything you'd do on a phone.

The community support model

This is giffgaff's most distinctive feature, and the one people are most sceptical about before trying it.

How it works: instead of a traditional call centre, giffgaff runs a community forum where members answer each other's questions. Top contributors earn "payback" points (convertible to account credit or cash). giffgaff staff moderate and step in for complex issues, but the first line of support is other customers.

Does it actually work? Yes, surprisingly well. In 15 years, I've posted in the community forum three or four times with questions. Every time, I had a useful answer within an hour, usually within minutes. The top contributors are genuinely knowledgeable and motivated by the payback system.

The trade-off: if you have a billing error, a technical fault, or an account issue that requires official intervention, you're dealing with giffgaff's in-house team via the forum or email. There's no phone line you can call to speak to someone immediately. For most people, this is fine. If you specifically need phone support as a non-negotiable, giffgaff is the wrong network for you.

The Trustpilot score of 3.9/5 from hundreds of thousands of reviews validates the model. For comparison, VOXI sits at 3.2/5 (UK consumer page), while corporate parent pages skew much lower (Vodafone Group at 1.4/5, Three's global page at 1.3/5). giffgaff's customer satisfaction holds up well for a budget network.

The referral reward

giffgaff's refer-a-friend scheme:

• Tier 1: £5 account credit when you activate a SIM with any goodybag (minimum £8)
• Tier 2: extra £10 each (you and referrer) if you join on an 18-month contract
• Maximum total: £15

The £5 arrives quickly after activation: no waiting two months like VOXI's referral. The extra £10 for an 18-month contract rewards commitment but isn't required.

How it compares: VOXI offers a voucher worth up to £40, but you wait two billing cycles. giffgaff's is smaller but faster. If the referral reward is a significant factor in your decision, VOXI wins on value; giffgaff wins on simplicity.

giffgaff FAQs

Is giffgaff any good in 2026?

Yes. After 15 years as a customer, giffgaff remains one of the best-value mobile networks in the UK. Plans start at 8 pounds per month for 3GB, it runs on the O2 network with 99%+ population coverage, and you can change or cancel every 30 days. It holds a 3.9/5 Trustpilot score from hundreds of thousands of reviews and has won uSwitch Network of the Year three years running. The main limitation is that it does not include unlimited social media data like VOXI does.

What network does giffgaff use?

giffgaff runs on the O2 (Telefonica) network. You get the same 4G and 5G coverage as O2 customers, covering 99%+ of the UK population. If O2 has good signal where you live and work, giffgaff will too.

How does the giffgaff referral work?

When you sign up through a referral link, order a free SIM, and activate it with a goodybag of at least 8 pounds, you receive 5 pounds in account credit. If you join on an 18-month contract instead, both you and the referrer receive an additional 10 pounds each, bringing the total to 15 pounds.

Is giffgaff better than VOXI?

For most budget-conscious users, yes. giffgaff is cheaper at every plan tier and has a better Trustpilot score (3.9 vs 3.2). However, VOXI includes unlimited social media data on all plans, which giffgaff does not offer. If you use Instagram, TikTok, and YouTube heavily, VOXI's unlimited social media data could make it more cost-effective despite the higher monthly price.

Can I keep my number when switching to giffgaff?

Yes. You can port your existing number to giffgaff by requesting a PAC code from your current network (text PAC to 65075 for free) and entering it during giffgaff activation. The switch typically completes within one working day.

Who giffgaff is best for

Best for:

• Budget-conscious users who want the cheapest reliable plan
• People who are comfortable with community-based support instead of a call centre
• Anyone who wants 30-day flexibility with no commitment
• Users who prefer the O2 network
• People who value high customer satisfaction (3.9/5 Trustpilot)

Less ideal for:

• Heavy social media users who would benefit from VOXI's unlimited social media data
• People who need phone-based customer support as a hard requirement
• Anyone in an area with poor O2 coverage (check coverage.o2.co.uk before switching)

The bottom line

giffgaff is worth it. After 15 years, it remains the network I recommend to anyone who asks, not because it's exciting, but because it's cheap, reliable, and honest. The O2 network works well across the UK, the 30-day rolling plans give you complete flexibility, and the community support model delivers a 3.9/5 Trustpilot score that most budget mobile networks would envy.

The one scenario where giffgaff isn't the best pick is if you're a heavy social media user. If most of your data goes to Instagram, TikTok, and YouTube, VOXI's unlimited social media data means you can get by on a smaller, cheaper plan than you'd need on giffgaff. For everyone else (and that's most people) giffgaff is the budget network to beat.

The £5 referral credit is modest, but it's free money on a free SIM for opening an account you can cancel in 30 days with no penalty. There's no risk in trying it.
