The telecom regulator has declared Grameenphone as the operator with the Significant Market Power in a move that can shake up the country's mobile telephony landscape.
As a result, GP might be charged additionally alongside regular taxes for customer acquisition.
The regulator plans to apply different prices to GP's charges and call rates and the benchmark for it might be different from other operators when it comes to quality of services.
GP said it wants the regulator to follow international best practices on the issue.
The SMP is a regulation that imposes restrictions on an operator once it corners 40 percent of the subscribers, revenues and spectrum.
