Having a reliable mobile network has never been more important. As the past year has tested our connections to their limits – in more ways than one – our phones have become ever more central to how we access the world.

Whether it’s calling loved ones, browsing the news, streaming music or keeping up with work, these days mobile networks have a lot of responsibility to keep the gears of our lives turning. At their best, they’re an invisible hand: making everything work in the background. At their worst, well… you better learn to love their customer service hold music.

Which mobile networks are holding their own, and which are leaving something to be desired? We’re asking you to give us your feedback on your energy supplier. In return, we'll enter you into a prize draw to win a £250 Amazon voucher .

Whether you’ve decided to change your mobile network this year, or you’ve stuck it out with the same provider you’ve had for ages, we want to know how satisfied you’ve been.

It helps us to get a better picture of the different mobile networks available. The survey will only take a few minutes to complete, and you can find it below.
