Mobile network operators are failing to meet businesses' need for predictable global pricing, according to a survey by analyst firm Ovum and the Enterprise VPN User Association (EVUA).
The survey of 42 EVUA members with telecoms budgets of more than £6m looked at usage of fixed, mobile, conferencing and outsourcing services. It found that CIOs' primary concern was the escalating cost of mobile services, particularly international roaming.
Other major concerns were integration, convergence and security, the survey revealed.
"Many of our members complain that the mobile operators are unable to provide multinational contracts. Most must be dealt with on a country-by-country basis, at a time when CIOs are trying to centralise more and more of their operations," said Ed Vonk, chief executive of the EVUA.
"With the increasing adoption of corporate mobile data, a more centralised approach to contracts is becoming essential," he added.
Pauline Trotter, principal analyst with Ovum's enterprise practice, said major users were likely to look to trusted relationships with fixed operators when they embark on convergence projects. "They have little loyalty to mobile operators," she said.
