Vodafone highlighted its commitments to mobile data and emerging market revenues, as it announced a 2.5 percent year-on-year rise in adjusted operating profits in the 12 months to March 2012.
However, the profit figure of €14.23 billion was 2.4 percent lower on a reported basis, when currency changes were taken into account.
Group revenues increased by 1.2 percent during the period on a reported basis, hitting €57.4 billion, with data revenues increasing by 22 percent.
In the UK, the firm's service revenues rose by 1.3 percent, while they were also up in Germany and India, which saw growth rates of 2.7 percent and 19.5 percent respectively.
However, the company announced that Spain saw an eight percent drop in service revenues, while a 1.9 percent fall was recorded in the Italian market.
Vittorio Colao, group chief executive of Vodafone, said: "Our focus on the key growth areas of data, emerging markets and enterprise is positioning us well in a difficult macroeconomic environment. Our commercial performance and our ability to leverage scale continue to be strong, enabling us to gain or hold market share in most of our key markets, and reduce the rate of margin decline."
In the firm's current financial year, which runs until March 31, 2013, the group said adjusted profits could reach between €13.73 billion and €14.72 billion.
Following the publication of the firm's financial results, its shares opened more than one percent higher on Tuesday morning.
