Vodafone Group Plc, the world's largest mobile phone operator by revenue, has secured a four-year deal to provide Oracle Corp with voice, data and management services to employees in the EMEA region.

Vodafone said its Global Enterprise unit would supply services to over 16,000 Oracle employees in the European, Middle East and Africa region on a fixed-fee, per-user basis.

Vodafone said the deal would offer Oracle the potential for significant savings and cost efficiencies due to the flat rate fee structures.

As well as our revolutionary per user pricing model, Oracle will benefit from the tools and consultancy that we offer to improve efficiency in both their fixed and mobile communications, Nick Jeffery, Chief Executive of Vodafone Global Enterprise, said in a statement.

Vodafone did not say how much the contract was worth.
