In news that may interest wireless communication device manufacturers, Vodafone Group Plc, the world's largest mobile phone company, has reported a smaller-than-estimated decline in full-year profit.
The figures were helped by demand for smartphone data services, Vodafone said.
Before interest, taxes, depreciation and amortization, earnings fell 0.4 per cent to £14.7 billion from a year earlier.
Sales, meanwhile, rose 3.2 per cent to £45.9 billion pounds, the company said in a statement.
"These numbers will be well received from the market as there were some concerns that they would miss estimates," commented Atif Latif, an analyst at Guardian Stockbrokers in London.
"They are finally starting to win back market share."
