Get an Amazon, PayPal, or Just Eat voucher worth up to £40 when you join VOXI using a refer-a-friend link: rewards are doubled until 7 October 2026.
VOXI's refer-a-friend scheme (branded Friends with Benefits) pays both parties a voucher (Amazon, PayPal, or Just Eat), released after the new customer's second monthly bill clears. The standard cap is £20, but VOXI's Double Rewards promotion lifts it to £40 for referrals made between 7 July and 7 October 2026. I joined VOXI in 2023 on a friend's code, and the voucher landed on both sides once I'd paid two months. The reward scales with the plan you choose.

VOXI is best for heavy social media users. If most of your data goes to TikTok, Instagram, or YouTube, the unlimited social media perk gives you far more usable data. Also suits students and anyone wanting a no-commitment 30-day plan.
VOXI is designed for:
VOXI's unlimited social media data sets it apart from giffgaff, SMARTY, and Three. giffgaff is cheaper but lacks social media perks. VOXI's Trustpilot rating is lower than giffgaff and SMARTY, reflecting mixed customer service experiences.
How VOXI compares to budget SIM-only competitors:
VOXI's Trustpilot rating (opens in new tab) is worth considering if responsive customer service is a priority.
