A callback, or rather Please Call Me as it has come to be universally known in South Africa, is a rather nifty concept that allows you to send a free SMS to any other Cell C customer asking them to call you back, usually because you don’t have any money on your phone – or are to cheap to use any of your own precious airtime!

Cell C allows each customer five Please Call Me SMS messages per day, and to send is actually pretty simple.

All you have to do is dial *111*cellphone number# (where ‘cellphone number’ is the friend’s phone you want to contact) and a Please Call Me SMS will automatically be delivered to the relevant person at no cost to you.

Nifty.
