VOXI vs giffgaff 2026: is VOXI better than giffgaff?

Affiliate disclosure: this post carries both a VOXI referral link and a giffgaff referral link, so I earn either way. The bigger reward to me is VOXI’s, and this page concludes giffgaff is the better pick for most people. Read the pricing table rather than the recommendation.

VOXI pays more, giffgaff pays faster and costs less. VOXI’s referral is a gift card worth up to £20, released only after your second monthly bill clears. giffgaff’s is a flat £5 in account credit, and it lands the moment you activate the SIM.

I have been a giffgaff member since 2011 and joined VOXI in 2023 on a friend’s code. Both rewards arrived, on both sides, in the windows each network advertises.

Referral reward comparison

VOXI is the higher number, and by a wide margin. But its voucher is conditional on you still being a customer two billing cycles later; giffgaff's £5 is yours the moment the SIM activates, and you can cancel the goodybag at the end of the month and keep it.

Neither network uses a code you paste at checkout. Both attribute the referral from the link you sign up through, so ordering direct and adding a code afterwards does not work on either.

Plan pricing

Aligned at common price points (rolling plans, no commitment):

giffgaff is cheaper at the entry tiers (£6 and £8), where VOXI has no equivalent. From £10 to £20 the two charge the same and VOXI adds an Endless perk on top, though giffgaff's £15 plan carries more data. At Unlimited both are £35 on a rolling plan, but giffgaff's 18-month contract drops Unlimited to £25/month, undercutting VOXI by £10/month at the headline plan.

The big differentiator: VOXI's Endless perks

Every VOXI plan includes uncapped data on a set of "Endless" apps:

• £10 tier: Endless Social Media: Snapchat, Instagram, WhatsApp, Facebook, X, Pinterest and Facebook Messenger don't draw from your allowance
• £12 tier: adds Endless Music: Spotify, Apple Music and the other major streaming apps
• £15+: adds Endless Video: YouTube, TikTok, Netflix, Prime Video and My5

giffgaff does not offer any equivalent.

If you're a heavy social media user, VOXI's Endless Social Media effectively gives you much more usable data than the headline number. The 20GB on the £10 plan plus uncapped Instagram, Snapchat and WhatsApp can outlast giffgaff's 26GB at £12 in real-world use, depending on how much of your usage skews toward those apps.

Network comparison

Coverage is comparable, and so is customer satisfaction: giffgaff leads on Trustpilot by 0.3. Which? separates them by nothing at all: both score 79%, joint 3rd of the 15 networks it surveyed. On awards the two have swapped places. VOXI took uSwitch Mobile Network of the Year in 2026, the title giffgaff held in 2025; giffgaff's 2026 win was the narrower Best Mobile Handset Contract Network. Neither award measures coverage on your street, which is what actually decides this. My longer reads on each network are is VOXI worth it and is giffgaff worth it.

Contract flexibility

Both networks offer 30-day rolling plans with no exit fees. giffgaff additionally offers 18-month contracts for those who want a lower monthly price in exchange for a commitment.

Which should you choose: VOXI or giffgaff?

Choose VOXI if:

• You use social media heavily (Instagram, Snapchat, WhatsApp), or TikTok and YouTube on the £15 plan
• The unlimited social media data would save you from needing a bigger plan
• You want the Vodafone and Three network
• You value the higher referral reward (up to £20)

Choose giffgaff if:

• You want the cheapest monthly price
• Customer service quality matters to you (3.6 vs 3.3 Trustpilot)
• You want the O2 network
• You prefer a quicker, simpler referral reward

The live link and current terms for each scheme sit on its own page: VOXI refer a friend and giffgaff refer a friend.

VOXI vs giffgaff FAQs

Is VOXI better than giffgaff?

For most people, no. giffgaff is cheaper below £10/month, holds a better Trustpilot score (3.6 against 3.3) and pays its referral credit on activation rather than after two monthly bills. VOXI is better in one specific case: if most of your data goes to Instagram, Snapchat or WhatsApp, the Endless Social Media allowance on every VOXI plan means a £10 VOXI plan can outlast a bigger giffgaff goodybag, and VOXI's referral voucher is worth up to £20 against giffgaff's £5.

Which referral pays more, VOXI or giffgaff?

VOXI, on the headline number. VOXI pays a gift card worth up to £20, against giffgaff's flat £5 in account credit. The trade-off is when and in what form: VOXI's voucher is spendable anywhere Amazon, PayPal or Just Eat is accepted but only arrives once your second monthly bill has cleared, while giffgaff's credit lands in days and can only be spent on giffgaff.

Is giffgaff cheaper than VOXI?

At the bottom of the range, yes, and by a wide margin: giffgaff starts at £6/month for 2GB and £8/month for 5GB, where VOXI's cheapest plan is £10/month. From £10 to £20 they charge the same, with an Endless perk on top at VOXI, though giffgaff's £15 plan carries more data. At Unlimited the rolling plans tie at £35/month, and giffgaff's 18-month contract beats both at £25/month.

Can I claim both the VOXI and giffgaff referral rewards?

Yes. They are separate networks with separate schemes, and neither excludes customers of the other. You would need a SIM from each, which means paying for both plans, so it is only worth doing if you were going to run two lines anyway.

How long does each reward take to arrive?

giffgaff pays its £5 on activation, usually within 24 hours. VOXI releases the voucher after your second monthly bill clears, so budget for roughly two months. On the referrer's side the gap is wider still: giffgaff Payback is paid out every six months, in June and December.

giffgaff vs VOXI: can I keep my number if I switch to either?

Yes, and the process is identical on both. Text PAC to 65075 from your current phone to get a PAC code, then enter it when you activate the new SIM; the number transfers within one working day and your old contract ends automatically. PAC codes expire after 30 days. Porting a number does not affect either referral reward: both are attributed from the link you ordered or signed up through, which happens before any number transfer.
