Five popular internet calling and message services, including Viber and Tango, resumed their countrywide operations after Wednesday midnight.
According to sources in Bangladesh Telecommunication Regulatory Commission (BTRC) and several private mobile phone operators, the services got operational after no further directives came from the government.
On Sunday, the government suspended Viber and Tango following a home ministry directive 'for the sake of the nation's security'.
The government the next day also suspended three more online voice and messaging services WhatsApp, mypeople and Line.
Intelligence agency sources said the opposition party leaders and activists were using Viber for planning subversive activities dodging intelligence surveillance, which led to the ban.
