The truth is: Airtel Money and M-Pesa each have their own advantages. M-Pesa is used by a large part of the population, allowing you to send money very cheaply to a large number of people. But Airtel Money recently cut their transfer fees and increased their daily transaction limit to Ksh. 150,000. So as you know, there are definitely advantages to both solutions.
But in the end, the two are very similar, and we highly recommend both. So go ahead and unlock which one suits you best
