VOXI vs giffgaff: which mobile referral is better?

VOXI and giffgaff are two of the most popular budget mobile networks in the UK. Both offer flexible plans with no long-term contracts, and both have referral schemes. But which one gives you more?

Referral reward comparison

VOXI's referral reward is significantly higher in value (up to £40 vs up to £15), but it takes longer to receive and requires you to stay for two billing cycles. giffgaff's £5 is quicker to claim but the full £15 requires an 18-month contract.

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 upwards the two are at price parity on raw data: VOXI matches giffgaff's data allowance and adds an Endless perk on top. At Unlimited, VOXI is £30 vs giffgaff's £35 rolling, but giffgaff's 18-month contract drops Unlimited to £25/month, undercutting VOXI by £5/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: Instagram, TikTok, Snapchat, Facebook, WhatsApp, X and YouTube don't draw from your allowance
• £12 tier: adds Endless Music: Spotify, Apple Music and the other major streaming apps
• £15+: adds Endless Video: Netflix, Prime Video and similar

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/TikTok/YouTube can outlast giffgaff's 26GB at £12 in real-world use, depending on how much of your usage skews toward those apps.

Network comparison

Both use major UK networks with comparable coverage. The significant difference is customer satisfaction: giffgaff scores 3.9 on Trustpilot while VOXI sits at 3.2.

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 (and the extra £10 referral bonus).

Which should you choose?

Choose VOXI if:

• You use social media heavily (Instagram, TikTok, YouTube)
• The unlimited social media data would save you from needing a bigger plan
• You want the Vodafone network
• You value the higher referral reward (up to £40)

Choose giffgaff if:

• You want the cheapest monthly price
• Customer service quality matters to you (3.9 vs 3.2 Trustpilot)
• You want the O2 network
• You prefer a quicker, simpler referral reward

For most budget-conscious users, giffgaff is the better value. For social media addicts, VOXI's unlimited social media data can genuinely save money on a lower-tier plan.
