BBM is still very much Thriving in Nigeria and South Africa

Check out the STATS:

Africa is clearly a mobile-first market, with the majority of people accessing the internet from mobile rather than desktop devices. We’re also seeing many people coming online for the first time in recent years, so BBM has seen quite a bit of growth.
Today, we have over 22 million registered customers in Africa, so it continues to be a strong market for us. Nigeria and South Africa are our two top markets in Africa (as I blogged about earlier this year here and here), and we continue to see strength in our user base across Android, iOS, BlackBerry 10 and BBOS. On iOS and Android, we see over half a million new users install BBM every single month. That growth rate continues to accelerate as network effects take root in several markets across the continent.
