State Minister for Post and Telecommunications Tarana Halim made the disclosure in a press briefing at the secretariat on Thursday afternoon, according to several television channels.
The decision came after 21 days of the blocking of Facebook.
The temporary ban on the social networking platform came shortly after the Supreme Court rejected review petitions by war criminals SQ Chowdhury and Ali Ahsan Mohammad Mujahid on November 18.
Citing security reasons, the government also blocked social networking platforms Whatsapp and Viber.
In Bangladesh, over 15 million people are active Facebook users and the number is rising.
