When it comes to mobile plans, British consumers are blessed with choice. There are more than 60 active mobile service providers in the UK, offering a broad selection of prices and features.
The 4 major carriers, EE, O2, Three, and Vodafone, each operate their own network. All the other providers “piggyback” off a major carrier’s network, but are otherwise completely independent of that carrier. Consumers can check coverage in their area with Ofcom’s free mobile coverage checker.
Because mobile plans are such a competitive space, consumers can save money by shopping around. We recommend comparing providers by things like price, contract length, customer service, and mobile coverage in your area. Most providers offer a choice of contract phones (including a phone and plan), SIM-only contracts, and Pay as You Go. Under Britain’s Consumer Contracts Regulations, consumers may cancel their mobile contract within 14 days of signup without being penalised.
