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 | giffgaff | |
|---|---|---|
| Your reward | Gift card up to £40 | Up to £15 account credit |
| When you receive it | After 2nd monthly payment | After SIM activation (£5) + contract start (£10) |
| Referral limit | Limited | Unlimited |
| Requirement | Stay active for 2 months | Activate SIM with goodybag |
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
| Data | VOXI | giffgaff |
|---|---|---|
| 5GB | £10/month | £8/month |
| 20GB | £15/month | £10/month |
| 40-50GB | £20/month | £12/month |
| 100GB+ | £25/month | £15/month |
| Unlimited | £35/month | £25/month |
giffgaff is cheaper at every tier. The price difference ranges from £2-10/month depending on the plan.
The big differentiator: unlimited social media data
VOXI includes unlimited data for social media apps on every plan. This means your usage of Instagram, TikTok, Snapchat, Facebook, WhatsApp, and YouTube doesn't count towards your data allowance.
giffgaff does not offer this perk.
If you're a heavy social media user, VOXI's unlimited social media data effectively gives you much more usable data than the headline number. A VOXI 5GB plan with unlimited social media could give you the equivalent data of a much higher giffgaff plan.
Network comparison
| VOXI | giffgaff | |
|---|---|---|
| Network | Vodafone | O2 |
| 4G coverage | 99%+ UK population | 99%+ UK population |
| 5G | Selected plans/areas | Selected goodybags/areas |
| Trustpilot score | 2.9/5 | 4.1/5 |
Both use major UK networks with comparable coverage. The significant difference is customer satisfaction — giffgaff scores 4.1 on Trustpilot while VOXI sits at 2.9.
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 (4.1 vs 2.9 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.
