Vodafone has been selected to provide mobile broadband services to energy supplier National Grid.
The two parties put pen to paper on a five-year deal, meaning that field engineers out fixing problems relating to gas and electricity will be able to have better access to information while on the job.
Vodafone has presented National Grid with a combined data and voice package, which includes the provision of 3G broadband-enabled laptops to National Grid staff.
"We conducted stringent testing to prove our network capabilities could meet and exceed National Grid's expectations," revealed Vodafone UK enterprise director Peter Kelly.
"We are pleased that a company that is so essential to the UK's energy supplies is relying on our network to ensure their workforce is mobile and able to operate, safe in the knowledge that we can connect them reliably to the information they need, wherever they are."
National Grid is administers the delivery of 11 million homes and businesses nationwide.
