The world's best performing non-voice services for mobile operators have been identified by research firm Analysys.
Broadband, SMS, video and email services were all represented, with the UK's O2 and 3 operators taking top spots for their texting and video streaming respectively.
"With falling voice average revenue per user (ARPUs), mobile operators now need to drive non-voice services", said study co-author Dr Alastair Brydon.
The service with the most potential was Vodafone's Fastweb DSL in Italy. "The top service may be a surprise to some," said Dr Mark Heath, co-author of the report. "However, DSL services can generate average monthly revenue of at least four times current non-voice ARPU levels. All of our top ten have great potential to drive operator ARPU."
