The telecom operators assured the government on Wednesday of their cooperation in getting details of customers but asked the home ministry to ensure cell phone users were not harassed by the police even as the Centre pitched in for thorough and quick subscriber verification exercise for security reason.

Due to either incomplete or unverified customer details nearly 30 lakh cell phone subscribers have been disconnected from their respective networks across the country till now.

The issue relating to subscriber verification especially in the states, where the operators claimed that the involvement of police has been creating problems, came up for discussion in a meeting of telecom operators, led by Bharti Group chairman Sunil Mittal on Wednesday with the Union home secretary G K Pillai.

Sources said that operators informed Pillai that subscribers were being asked to be present at police stations for verification and termed it as harassment. There is no coordination between the Centre and the states over the mechanism to be followed to complete the verification process.

In the wake of security threat and terrorist using cell phones for carrying out their terror operations in India the subscriber verification has become a major issue.
