Muhith, who is now in Washington to attend the IMF and World Bank's Annual Spring Meeting, met with Telenor President and CEO Sigve Brekke.
"I told the Telenor president that I have one only complaint, the one about huge call-drops.
"He admitted it and said the spectrum allotted to them is not sufficient. He says the spectrum is divided in two parts-- data and voice. The data spectrum has unused capacity, but that's not the case for voice and that's why the call drops occur," the finance minister told bdnews24.com after the meeting.
Launched in 1997, Grameenphone claims to have 99 percent surface coverage in the country and a more than 50 million-strong subscriber base.
Call-drops are not new for Grameenphone. The operator had announced that it would compensate the subscribers for dropped calls last year but later withdrew the offer ‘without advising the customers.'
Norway's Telenor, which runs businesses in several other countries but makes more money in Bangladesh than from its other subsidiaries including India’s Uninor, owns 55.8 percent share in Grameenphone.
Asked when the auction might happen, he replied: "Well, I will have to head for Japan in the first week of May for the ADB annual meeting. Then there's the budget… the auction will be held after that."
