Network Coverage And Performance

Turkcell covers more than 98% of Turkey's population with 4G service and launched 5G across all 81 provincial centers on April 1, 2026.

Urban centers including Istanbul, Ankara, Izmir, Antalya, Bursa, and Gaziantep receive excellent 4G signal across metro tunnels, commercial districts, and suburban areas.

Turkey's 5G rollout operates in Non-Standalone (NSA) mode, utilizing the 700 MHz and 3.5 GHz spectrum bands allocated in the October 2025 auction, according to Turkey's Information and Communication Technologies Authority (BTK).

Turkcell secured 160 MHz of 5G spectrum in the October 16, 2025 auction — approximately 25% more spectrum than the nearest competitor — investing USD 1.2 billion (excluding VAT), according to the Turkcell Full Year 2025 Results published March 2026. The operator also holds valid 2G, 3G, and 4.5G authorizations extended until December 31, 2042 under the same agreement. Nationwide 5G coverage at scale is projected by 2027–2028, according to Turkey's Ministry of Transport and Infrastructure.

Turkcell's 4G LTE network operates across key frequency bands including 700 MHz (Band 28) for rural and indoor penetration, 1800 MHz (Band 3) for urban density, and 2600 MHz (Band 7) for high-capacity urban zones. These three band tiers ensure both wide geographic reach and high-speed throughput in densely populated areas.
