The highest number of call drop incidents (103,43,00,000) occurred in Grameenphone (GP) network in the last 12 months, according to Bangladesh Telecommunication Regulatory Commission (BTRC).
The statistics of the call drop incidents of all the mobile operators from September 2017 to September 2018 was disclosed by the telecomm regulator on Monday.
According to the report, telecommunication operator Robi recorded around 76,18,00,000 calls drop incidents while the number in Bangalink network was 36,54,00,000 and 6,00,00,000 times in the network of the government-run operator TeleTalk, reports UNB.
On Monday, the BTRC also issued letters to all the mobile operators seeking explanation on the issue and asked them to submit reports within next five working days.
Terming the call drop incident as a major problem, Posts, Telecommunications and Information Technology Minister Mustafa Jabbar said, "We have recently approved a Quality of Service (QOS) Policy and directed the BTRC to monitor all the networks."
The BTRC was also asked to send letters to the mobile operators to ensure quality services, he added.
He also said the operators do not have sufficient spectrum. "As the Mobile Number Portability services have been introduced recently, the operators will be bound to ensure quality services," he hoped.
