He continued, '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.'

BT Business launched BT One Phone last month with a consumer mobile offering set to be unveiled later this year.

Paolo Pescatore, an analyst with CCS Insight told Mobile that BT's latest offering was very competitive. 'No 4G LTE premium and unlimited BT Wi-Fi at no extra cost is a statement of intent and throws down the gauntlet to rivals,' he said.

'Also, it is the strongest indicator yet of how its consumer offering will look like,' he added.
