The worst culprit was Spain, showing a significant drop of 17.8% to reported service revenues of £935m. The UK fared better but still fell 1.4% during the quarter to just under £1.2bn.
Vodafone attributed the UK results to increased competition and a weaker economy, while Italy and Spain remained “challenging environments”.
The company did perform better in its emerging markets, with a 1.2% service revenue increase in India alone.
