Nokia Siemens Networks had reassured customers over the merger that created the telecom equipment maker, after uncertainty dented sales in the second quarter, a Reuters report said.
The Reuters report said April-June sales at the network equipment venture, owned equally by Nokia and Siemens, fell more than 10%, both from the first quarter and a year earlier.
The report added that some of the total of about 600 customers of the joint venture, formed on April 1, were cautious about placing new orders until they had more details of the company's product portfolio and strategy, Simon Beresford-Wylie, Nokia Siemens top executive, said.
The world's second-largest mobile networks company after Swedish rival Ericsson, Nokia Siemens has been able to retain most customers, despite aggressive price cuts at Ericsson, Beresford-Wylie said.
Restructuring programs at newly merged Nokia Siemens and Alcatel-Lucent gave Ericsson the opportunity to steal market share by undercutting prices, analysts have said
Beresford-Wylie said the firm could consider acquisitions in future but declined to comment, the Reuters report further said.
