Most people in West Africa still don't have mobile phones, according to a report by mobile phone industry analysts GSMA.
The report says there are only 185 million unique mobile subscribers in West Africa - which it works out as 48% of the population.
It goes on to predict that West Africa will get over that halfway point in 2020.
Mobile technologies and services contributed $52bn (£45bn) in economic value in West Africa last year according to the report.
That was equivalent to 8.7% of the region's GDP.
