DoT has concluded that SLD amounts to violation of national routing plan, numbering plan and unauthorised bypass of national long distance traffic to avoid payment of access deficit charge. It was a violation of licence conditions leading to loss to the exchequer.
Bharti and Hutch started SLD services in the first half of 2002 without filing any tariff plan with the Telecom Regulatory Authority of India (Trai).
Under SLD, subscribers traveling outside their home networks were given a new number on the same SIM card and recognised as local subscribers when roaming within the companys network.

Officials said DoT issued instructions to all cellular operators on June 20, 2003 to stop the SLD services immediately.
However, according to DoTs communication to Trai, Bharti continued the SLD services till January 11, 2005 while Hutch continued it till December 31, 2003.
According to DoT officials, the matter is under examination and the department may soon send notices to the companies asking them why action should not be taken against them.
