About TCI
TCI was established in 1971 and controls Iran's entire fixed-line telephone and broadband infrastructure. Every private ISP in Iran leases last-mile access through TCI copper and fiber networks.
The company was partially privatized in 2009 when Mobin Trust Consortium acquired a majority stake. TCI reported operational revenues of approximately 21.5 trillion Iranian tomans in fiscal year 1402 (March 2023 to March 2024), with broadband revenues growing 22% in the same period.
TCI Plans and Services
TCI offers several internet plans across different technologies and price points.
TCI provides ADSL broadband from 2 to 16 Mbps across most Iranian cities and towns. VDSL service reaches up to 50 Mbps in select urban areas near central offices. Fiber-to-the-home delivers 50 to 100 Mbps where infrastructure exists.
The National Fiber Optic Plan targets 20 million premises by end of 2025 but reached only 10 million by March 2024. TCI prioritizes Tehran and high-value urban markets for fiber deployment. ADSL remains the dominant fixed-line technology for millions of households using copper infrastructure dating back decades.

TCI Speed Test FAQ
What is TCI in Iran?
TCI (Telecommunication Company of Iran) is the state-owned company that controls all fixed-line telephone and broadband infrastructure in Iran. Every ISP in the country, including Shatel, Pars Online, and HiWeb, leases last-mile copper and fiber access from TCI to reach customers. TCI was established in 1971 and serves 10.89 million fixed broadband subscribers. The company was partially privatized in 2009 when Mobin Trust Consortium acquired a majority stake. TCI provides ADSL, VDSL, and fiber-to-the-home services directly to consumers while also wholesaling infrastructure to private ISPs.
How fast is TCI broadband in Iran?
TCI averaged 38.2 Mbps download speed on fiber connections in Q3 2025 and reached 55.7 Mbps in Tehran. Most ADSL subscribers get 2 to 16 Mbps depending on distance from the central office. VDSL delivers up to 50 Mbps in select urban areas near exchanges. Fiber-to-the-home provides 50 to 100 Mbps where infrastructure has been deployed. Speeds drop during evening peak hours between 7pm and 11pm due to international traffic throttling through TIC. The National Fiber Optic Plan aims to bring faster speeds to more households, but as of March 2024, only 10 million of the targeted 20 million premises had fiber access.
Is fiber available from TCI at my address?
TCI fiber-to-the-home is available in Tehran and parts of major cities like Isfahan, Mashhad, Shiraz, and Tabriz. As of March 2024, fiber reached approximately 10 million premises nationwide. Coverage concentrates in wealthy urban neighborhoods and high-density residential areas. Most TCI subscribers still use ADSL on copper telephone lines. Contact TCI directly or visit a TCI office with your address to check fiber availability. If fiber is unavailable, ADSL at 2-16 Mbps or VDSL at up to 50 Mbps may be the alternatives depending on your distance from the nearest central office.
