Want to switch mobile phone provider but don't know where to start? Our latest satisfaction survey results will help you make the right choice.

Find out which mobile phone networks have been rated as Recommended Providers - and see which ones you should avoid based on the views of thousands of phone users from across the country.

In our latest satisfaction survey we spoke to more than 3,500 customers of 13 of the biggest phone providers including EE, O2, Vodafone and Three. They told us exactly what they thought of their phone company, from the customer service on offer to the value for money they get.

Five phone companies did so well that we've made them Which? Recommended Providers. The names may surprise you but all five offer good deals and great service.

In this guide we'll:

  • tell you which mobile phone networks were rated as Which? Recommended Providers
  • give you a full breakdown of how each provider is rated for key factors, such as the customer service they offer
  • report quotes from real customers on their experiences
  • look at each network's coverage throughout the UK
  • highlight each provider's deals and incentives.

Only logged-in Which? members can access our exclusive reviews and recommendations.
