BT has launched a series of 4G business plans to coincide with the fact it is now offering 4G as standard to all of its corporate customers.
The telecoms provider said the plans will allow small and medium-sized companies to tap into the faster mobile internet speeds offered by 4G at "no extra cost".
Prior to today, BT offered 3G contracts to its business customers as standard but anyone that wanted access to 4G was required to sign up to a more expensive 4G contract.
The new contracts, which can be viewed in full here, also offer unlimited access to BT's public wi-fi, which is available at more than five million hotspots across the UK.
The new mobile plans are being introduced just weeks after BT Business launched the BT One Phone, which is a service designed to improve mobile coverage and manage calls from a computer, among other things.
BT withdrew from the mobile market in 2001 when it sold off the BT Cellnet arm to Telefonica, who relaunched it as O2 in 2002. However, it acquired 4G spectrum coverage of its own in an Ofcom auction last year, and in March, it signed the agreement with EE that enabled BT to access EE's 2G, 3G and 4G services.
Graham Sutherland, CEO at BT Business, said: “Our research shows that 24 percent of employees now work regularly out of the office. As part of our strategy to offer a portfolio that provides value for money and meets the changing needs of businesses, we’ve designed our new mobile plans to cater for this.
"Our new plans give customers the connectivity they need to help them stay productive when out and about, along with the flexibility to choose a plan that suits their way of working,” he added.
