Mobile money interoperability in Kenya has been a long time coming. This will allow mobile money users across mobile networks to move money to each other and into each other’s wallets. Before this, one could only send a withdraw message for from the same carrier to withdraw at the carrier’s agency, not into their wallet.
You would then need to deposit the money at your carriers agents. This is no-longer the case as Airtel and Safaricom’s inter-operability goes live today. Telkom Kenya is said to come a bit later. No word on Equitel, the other major mobile money player.
Now for Airtel Money and Safaricom, here’s how to go about it. Some carriers look quite excited about this, while others seem like they would rather it stays away. Notice below how one of them has buried it quite deep.
