Staff have been informed that the UK joint venture between T-Mobile and Orange will transfer 220 staff to T-Systems.
T-Systems confirmed that it "has signed a new, seven-year outsourcing contract for IT services with Everything Everywhere." No value was given but according to sources it is about £700m.
The deal is for the delivery of desktop services, datacentre operations and infrastructure management, IT applications support and ITIL support processes to support 16,000 staff.
It also triggers off a move into the cloud. "The contract sets out a path for migrating 40% of Everything Everywhere's IT estate onto T-Systems' Dynamic platform within three years," said the T-Systems statement.
T-Systems already provided IT services to T-Mobile, which is also owned by Deutsche Telekom but the Orange UK IT infrastructure, which is done in-house, is said to be twice as big as its T-Mobile equivalent.
