Overview of Both Networks

It’s ideal for people who want control over their spending and dislike the rigidity of fixed-term contracts.
About Voxi

Key Differences
While Giffgaff vs Voxi is known for its flexibility and affordability, Voxi stands out for its perks and modern approach. Giffgaff vs Voxi suits users who want simplicity and value, while Voxi attracts those who live on their phones, streaming and scrolling daily.
Plans, Pricing, and Value for Money
Giffgaff vs Voxi Goodybags are some of the most flexible plans on the market. You can buy one for a month and cancel or switch the next without penalties. As of 2025, Giffgaff offers data options from 2GB to unlimited, with prices ranging roughly from £6 to £35. All plans include unlimited calls and texts, and unused data doesn’t carry over.

Voxi’s pricing structure is slightly different. Plans start around £10 per month for smaller data bundles and go up to £35 for unlimited data. However, the major advantage is Voxi’s “Endless Social Media” — apps like Instagram, WhatsApp, Facebook, and TikTok don’t use your main data. This is a huge perk for users who spend hours on social media daily. Voxi also includes 5G in all its plans at no extra cost, giving it an edge in terms of modern connectivity.
When it comes to value, Giffgaff often wins for price-conscious users. But for those who prioritize data-heavy features, Voxi delivers extra perks that justify the slightly higher cost.
Network Coverage and Performance
Giffgaff Coverage
Because Giffgaff runs on O2’s network, it benefits from one of the UK’s most extensive coverage footprints. O2 is known for strong indoor signal penetration and reliable 4G performance, especially in suburban and rural areas. In 2025, Giffgaff also offers 5G access in major cities like London, Manchester, and Birmingham, though speeds may vary based on location.
Voxi Coverage
Voxi uses Vodafone’s infrastructure, offering robust nationwide coverage and excellent 5G performance in urban centers. Vodafone’s 5G rollout has been faster than O2’s in some regions, meaning Voxi users might experience better download and streaming speeds, particularly in densely populated areas.
Performance Comparison
Independent tests often show that Vodafone’s average data speeds slightly outperform O2’s, giving Voxi a marginal advantage in speed. However, Giffgaff tends to deliver more consistent reliability in rural zones. Ultimately, the “better” network depends on where you live and travel most often — Vodafone’s strength lies in speed, while O2’s lies in stability and reach.
