Answer 1

Large majorities in the 11 emerging and developing countries surveyed either own or share a mobile phone, and in every country it is much more common to own one’s own phone than to share it with someone else. In seven of these countries, half or more now use smartphones – and smartphone use is especially common among younger and more educated groups.

Meanwhile, access to tablets or computers is rarer. In only one country – Lebanon – does a majority (57%) have access to a working desktop, laptop or tablet computer in their household, and mobile devices play a prominent role in how people access the internet and their social networks in many of these nations.
