Stockholm: Ericsson (ERICb.ST) said on Thursday it was aware some of its mobile operator customers were suffering outages and it was working with them to solve the problem.
Mobile operators O2 (TEF.MC) in Britain and Softbank (9984.T) in Japan reported disruptions to data services on Thursday affecting millions of customers.
O2 said the problem was caused by an issue at one of its suppliers.
“We are aware of the issue and are working together with our customers to solve it as soon as possible,” an Ericsson spokesman said.
