Leading UK supermarket Tesco has today launched a free Wi-Fi service in its Tesco Extra stores nationwide following a successful trial.

It now means that consumers across Britain have a new tool to compare prices and read product reviews while they shop for their groceries.

Provided by Telefónica UK and based on O2 Wi-Fi‘s technology platform, the tech solution will give Tesco Clubcard holders free and unlimited access to the service as long as they sign up with their loyalty scheme number.

Consumers who do not own a Clubcard are able to use the service for 15 minutes free every 24 hours.

Mike McNamara, Chief Information Officer at Tesco, said: “We‘re proud to be the first UK supermarket to offer nationwide access to free Wi-Fi.

“People are increasingly using a variety of digital services and we‘re excited by our customers‘ reaction to the new service.”

Tesco received encouraging feedback from users during the recent trial, and the survey also revealed that 71 per cent of customers accessed the Wi-Fi via smartphone, 11 per cent on a tablet device and nine per cent through their laptops.

Retailers from other sectors have already launched Wi-Fi services for their customers.

Department store group John Lewis and electricals specialist Phones 4u unveiled their versions of the internet platform in the autumn.
