ReferBonus may receive a reward if you sign up through links on this page. It never costs you anything, and in most cases you get a bonus too.
Cash referral bonus · Broadband & Mobile
£40 vouchers
Refer a friend to VOXI and once you've both paid for two months, you each get a £40 Amazon, PayPal or Just Eat gift card — doubled from the usual £20 under VOXI's current Double Rewards promotion.
Opens VOXI's site — the reward tracks automatically via this link.
VOXI is Vodafone's youth-leaning SIM-only network, built around unlimited data for social apps — Instagram, Snapchat, WhatsApp, TikTok and others don't count against your allowance on eligible plans — while running on Vodafone's full network coverage. Plans are rolling 30-day SIM-only with no credit check, so there's nothing to commit to beyond a month at a time. The refer-a-friend scheme pays out on a delay rather than at sign-up: both you and your friend need to have paid for two full months of service before either reward triggers, at which point you each get an email to choose a gift card — Amazon, PayPal or Just Eat — and redeem it within 90 days. The standard reward is £20 each, but VOXI periodically runs a Double Rewards promotion that lifts it to £40; the doubled rate only applies to referrals made within that live window, so check current terms before assuming it still applies.
