BT has begun rolling out its InLinkUK smart kiosks in Sheffield, Newcastle and Gateshead.
The devices, which offer ultrafast Wi-Fi speeds of up to 1Gbps, have so far been installed in London, Leeds, Southampton and Glasgow and could eventually replace more than 1,000 pay phones across the country.
According to BT, InLinks offer the UK's fastest free public Wi-Fi service available, as well as free phone calls and a range of new digital services.
This includes mobile device charging, access to maps, directions and local services, as well as a BT Phone Book app that enables users to search for individuals and businesses.
Each digital display also provides real-time information relating to the area, such as the weather forecast and public transport service updates.
Since each unit is funded by advertising revenue, they are free for people to use.
Neil Scoresby, General Manager for Payphones and InLink at BT, recently said the company is "really excited" by the popularity of InLinks and declared them "a hit with customers".
"We’re in discussion with many local councils about installing more InLinks and we’re looking forward to rolling out InLinks to more London boroughs and major cities across the UK," he commented.
