The shutdown has been called by TRS to protest the Centre's "indecision" on granting statehood to Telangana. BJP and Telangana Joint Action Committees are supporting the bandh, which comes a day after the all-party meeting on Telangana in New Delhi.
Educational institutions at many places remained closed and examinations of Kakatiya and Osmania Universities were postponed.
Pro-Telangana supporters held protests accusing the Centre of failing to arrive at a decision on carving out a separate state.
The bandh was peaceful so far and elaborate security arrangements have been made to deal with any untoward incident, police said.
After the meeting of political parties yesterday, Home Minister Sushilkumar Shinde said a decision on the long- pending Telangana issue will be announced within a month.
However, the TRS, which is spearheading the statehood agitation, was not satisfied with the announcement.
"They have said this over a hundred times. They have not fulfilled their promises. They have cheated the people of Telangana again," TRS chief K Chandrashekar Rao had told reporters after coming out of the meeting chaired by Shinde.
