This, however, has not been the case, raising concern among operators in the sub-sector who claim they have not broken even yet, not to talk of making profit after years of investment.

Consequently, while there is a glut in bandwidth capacities at the shores, network expansion to hinterlands and expected falling prices in subscriptions that would fuel explosive growth in mobile broadband and other Internet related services, are still seriously constrained.
