Mobile penetration rates in emerging markets are set to soar over the next five years, reaching 95% in 2013.
And the subscriber base of the 34 emerging markets included in the study is likely to grow from 2.1 billion now to 4.3 billion in 2013, according to research conducted by Tariff Consultancy.
China and India will remain the two largest markets due to their population, but the fastest growing mobile markets will be countries like Indonesia, Afghanistan and Iraq.
Mobile broadband penetration is also increasing.
Although the cost of 3G handsets remains prohibitively expensive for the mass market, the ready availability of USB dongles, and the introduction of flat rate tariffs and larger data allowances will spur adoption.
That said, mobile broadband penetration is not likely to grow at the same rate as in Europe. Market analysts Analysis Mason believe that up to a quarter of broadband-equipped European homes will be mobile only by 2013.
Among the Asian markets included in the Tariff study were China, India, Malaysia, Vietnam and the Philippines.
