Phone credit low? Africans go for "beeping"

By Andrew Heavens

KHARTOUM (Reuters) - If you are in Sudan it is a 'missed call'. In Ethiopia it is a 'miskin' or a 'pitiful' call. In other parts of Africa it is a case of 'flashing', 'beeping' or in French-speaking areas 'bipage'.

Wherever you are, it is one of the fastest-growing phenomena in the continent's booming mobile telephone markets -- and it's a headache for mobile operators who are trying to figure out how to make some money out of it.

You beep someone when you call them up on their mobile phone -- setting its display screen briefly flashing -- then hang up half a second later, before they have had a chance to answer. Your friend -- you hope -- sees your name and number on their list of 'Missed Calls' and calls you back at his or her expense.

It is a tactic born out of ingenuity and necessity, say analysts who have tracked an explosion in miskin calls by cash-strapped cellphone users from Cape Town to Cairo.

"Its roots are as a strategy to save money," said Jonathan Donner, an India-based researcher for Microsoft who is due to publish a paper on "The Rules of Beeping" in the high-brow online Journal of Computer Mediated Communication in October.

Donner first came across beeping in Rwanda, then tracked it across the continent and beyond, to south and southeast Asia. Studies quoted in his paper estimate between 20 to more than 30 percent of the calls made in Africa are just split-second flashes -- empty appeals across the cellular network.

The beeping boom is being driven by a sharp rise in mobile phone use across the continent.

Africa had an estimated 192.5 million mobile phone users in 2006, up from just 25.3 million in 2001, according to figures from the U.N.'s International Telecommunication Union. Customers may have enough money for the one-off purchase of a handset, but very little ready cash to spend on phone cards for the prepaid accounts that dominate the market.
