Reward Mobile is a UK mobile reseller selling SIM only and pay monthly contracts on EE and Three networks, typically at a discount to going direct, with cashback offers on many plans.
Reward Mobile's appeal is in the savings. As an authorised reseller of EE and Three plans, it can package discounts and cashback offers that aren't available going direct to the network. Reported savings can be significant on equivalent EE plans. The mobile service itself coverage, ongoing account management for the live service is provided by EE or Three directly; Reward Mobile handles the sale, any cashback, and onboarding.
Reward Mobile is a retailer of EE and Three contracts rather than a mobile network itself. The SIM and service you receive are issued by EE or Three, so coverage, in life customer service, and account management for the live service sit with the underlying network. Reward Mobile's role is the initial purchase, any sign up cashback, and onboarding.
Many Reward Mobile plans include cashback paid by bank transfer within a defined window after connection. The cashback is processed automatically rather than requiring you to claim it each month. Always compare the effective monthly cost after cashback against equivalent direct deals and other retailers to confirm the saving.
