Get an Amazon, PayPal, or Just Eat voucher worth up to £40
Get £5 giffgaff credit when you activate a new SIM
If you're switching mobile network or buying a new phone, a referral code can save you up to £40. VOXI offers gift cards worth up to £40 (double rewards until October 2026; normally up to £20) and giffgaff gives £5 in account credit. Both operate on major UK networks (Vodafone and O2 respectively) with strong coverage across the country. Affordable Mobiles' refer-a-friend cashback scheme is currently paused.
Best UK mobile deals in 2026
The best mobile deal is the cheapest plan with enough data for how you actually use your phone, and head-term comparison is owned by sites like Uswitch and MoneySavingExpert. What we add is the sign-up saving: VOXI's voucher worth up to £40 (doubled until October 2026; normally up to £20) and giffgaff's £5 credit. Neither uses checkout codes. Affordable Mobiles is a reseller whose refer-a-friend scheme is currently paused; its savings are built into the contract price.

What are the best UK mobile deals in 2026?
For the networks we cover, the sign-up saving is a refer-a-friend reward rather than a discount code: VOXI gives a voucher worth up to £40 (double rewards until 7 October 2026; normally up to £20) and giffgaff gives £5 in credit. Neither runs public voucher codes. Affordable Mobiles' refer-a-friend cashback is currently paused; its deals are priced into the contract rather than a code you paste at checkout.
