"This is just the beginning," Safaricom CEO Bob Collymore said in a statement adding that the decision is to make data bundles affordable in the wake of increased internet penetration.
He said Safaricom has seized of the fact that more Kenyans go online for everything from business to studying to social networking.
"We see an opportunity to narrow the access gap by connecting even more people to the Internet, especially the youth," Collymore said.
During the telco's AGM two weeks ago, the CEO said the company was aware of frequent customer complaints that mobile data is depleted too fast.
He offered more transparent and user-friendly data experiences going forward.
"Safaricom exists to transform lives, and we hope that by leveraging the strength of our network and giving our customers what they want."
Latest Communications Authority of Kenya data indicates Safaricom’s share of the voice traffic dropped to 72.5 per cent in the quarter to December 2017, from 80.6 per cent in a similar period a year earlier.
This was a market drop of 8.1 per cent, while rival Airtel Kenya gained 22 per cent up from 13.5 per cent in a similar period the previous year.
The latter has a data bundle which gives its subscribers 2GB for Sh99 daily.
