The SMSes on the attacks emanated after the Assam ethnic violence.
"It is a matter of concern (students leaving southern states fearing attack) and such incidents would have serious ramification in the long run," Meghalaya chief minister Mukul Sangma told reporters after a cabinet meeting.
"We have checked with our counterparts and found that most of the information being circulated through SMSes are rumours," Sangma said.
He said a delegation would be sent to the affected states and the union home ministry was being approached to facilitate the visit.
"The director general of police and the chief secretary are in constant touch with their counterparts in the states. I have also taken up the matter with my counterparts there," Sangma said.
Meghalaya Police have also set up a helpline 91-8575001111.
