Commuters in London and Birmingham are now able to hitch a super-fast ride in a 4G-enabled hackney carriage.
EE has launched a 50-strong fleet of taxis offering free access to super-fast mobile broadband, delivered via an in-car Mi-Fi wireless router.
This acts as a mobile 4G hotspot, ensuring each 4GEE taxi is able to connect to the firm's next-generation broadband network.
According to EE, more than 200,000 black cab journeys are taken across London alone each day.
A fifth of consumers surveyed by the broadband provider said they would have a less stressful day if they could access the internet in their taxi.
And as such, EE is seeking to improve the travel experience for cab passengers.
Spencer McHugh, Director of Brand at EE, explained that the first motorised black cabs hit the streets in 1901.
He said EE is "bringing this icon of British transport into the 21st century with a 4G make-over".
"We hope this trial will demonstrate the benefits of a superior online experience as users can browse, download, catch up on emails, Tweet and check Facebook literally at the speed of light," Mr McHugh added.
"We can't make taxi journeys any faster but we can certainly speed up people’s [browsing]."
EE is running the free 4G service for three months.
London will have 40 traditional Hackney carriages fitted with a Mi-FI router, while Birmingham will have ten.
EE was the first UK broadband provider to launch 4G services, introducing super-fast mobile broadband in 11 cities in October 2012.
The firm used its exisiting 1,800MHz spectrum to achieve this goal, following a lengthy Ofcom consultation.
