The government blocked Viber and Tango, popular internet calling and message services, on Sunday morning. Viber and Tango was most popular service along with skype and Facebook.
According to sources at the mobile phone operators, Bangladesh Telecommunication and Regulatory Commission (BTRC) authorities sent a letter and verbal directive to them to stop Viber and Tango services from 5:00am.
The BTRC sources said the authorities sent a directive to mobile phone operators first and then to International Gateway authorities in this regard.
Initially the operators were asked to suspend the services till 6:00pm but the ban has now been extended to 11:59pm. BTRC authorities have blocked the services in the country only after the home ministry`s directive. The government has taken the decision for the sake of security.
