Mobile telecommunications giant, MTN has blocked calls coming to their network from fellow competitor, Expresso beginning November 1, 2014. 

MTN last week notified its subscribers of the decision through text message indicating it was due to circumstances beyond its control.
“Due to uncontrollable circumstances, MTN customers cannot receive calls from Kasapa [Expresso] from Nov. 1. You can, however, call Kasapa customers. Sorry for the inconvenience.

But Joy Business gathers that the action has been influenced by the inability of Expresso to settle debts owed MTN in termination fees.  

MTN has over 13 million subscribers on its network while Expresso, a CDMA network has about 124,000 subscribers, according to August figures from the National Communication Authority (NCA).

The development could affect a lot of businesses that uses Expresso lines for their day to day operations.
