Telecommunication Company of Iran, or TCI (, romanized: Sherkat-e Moxāberāt-e Irān), is the fixed-line incumbent operator in Iran offering services in fixed telephony, DSL and data services for both residential and business customers, all throughout the country. It was established in 1971 with a new organizational structure as the main responsible administration for the entire telecommunication affairs.
TCI maintains 30 provincial subsidiaries and two brands - MCI (Hamrahe Avval or Mobile Company of Iran) and FCI (Ashenaye Avval or Fixed-line Company of Iran) that provide fixed-line telephone service, data services, mobile services, high-speed internet and soon wireless services. About 99% of the fixed-line telephone subscribers and 61% of the mobile subscribers in Iran belong to TCI's affiliates.

On 2016 the Director of TCI announced the merger of its provincial subsidiaries and the MCI into a single business unit that allow to utilize the powerful synergies and maintain leading positions on the national telecoms market.[2]
