In Tanzania they call it beeping. In Nigeria they call it flashing.
What do you call ringing your friend on her mobile then hanging up before she answers so she can that you called, but you don’t have to pay for the call?
In Tanzania, simple systems exist so that friends can communicate with their mobiles for free by beeping and letting it ring different numbers of times.
