Revenue opportunities for mobile operators, outside of voice, messaging and mobile data termination, will reach US$120 billion by 2024 - up from US$67 billion this year, according to a new report.

Australia ranks 50th for the average cost of a gigabyte of mobile data among 230 countries which were studied by the British website cable.co.uk. Data from 6313 mobile data plans was collected, prices were computed in US dollars and local currencies and the countries were ranked.

With OVO's data allowances at least doubling across most plans during 2018, its provocation of fellow mobile and data players to capture cunning customers has reached its highest count yet.
