LOL, Africa is not a country.

M-Pesa is a franchise, available to mobile network operators in many countries, but from a quick glance, Rada is (today), only available with Safaricom M-Pesa (and in Kenya, for KSh conversions only).

I think the only friction in using Rada will be in applying for the API key where they scrutinize the application, where if you are honest and say it is a form of a bitcoin or "crypto" exchange, they will decline granting of the credentials. Will be interesting!
