This payment gateway is a must for any business who want to establish a presence in Africa.

E-commerce in Africa boosted by Mobile Money
E-commerce is growing significantly in Africa, thanks to local actors (Jumia, Abidjandeal.com…) and major international retailers.
However, this growth has been slowed down by the lack of available payment methods. Cash continues to be the preferred payment method, card penetration is still very low and Paypal doesn't offer cash out.

You should definitely consider integrating this feature.
