Mahanagar Telephone Nigam Limited (MTNL) is a state-owned telecommunications service provider in the metro cities of Mumbai and New Delhi in India and in the island nation of Mauritius in Africa.

The Government of India currently holds 100% stake in the company.[3] In recent years, MTNL has been losing revenue and market share heavily due immense competition in the Indian telecom sector.
