I recently ported my line to Turkcell. I noticed that although Turkcell claims to be the leader in coverage in Turkey, it does not have reception where my workplace is located. I frequently experience interruptions in calls and internet service. Just like in Turkey in the 1990s, I find myself constantly asking, "Can you hear me now?" while trying to move to higher ground or lifting my phone up to get a signal. Moreover, I work in a central location, on the ground floor of a two-story building with open surroundings and good visibility. When I filed a complaint about this issue on April 16, 2025, I received the following response: "Dear customer, we have reviewed your request. We examined the area you reported experiencing signal/coverage issues in, and unfortunately, we cannot provide a positive response at this time. We will consider your request in our future planning. Have a nice day." In short: they admitted the signal is poor and it won’t be fixed anytime soon. As this is a defective and inadequate service, I questioned why I should be paying for a line I cannot use and called customer service to express my desire to switch operators. Even though it hasn’t been a full month yet, they said I would be charged a cancellation fee of ₺699. As far as I can tell, they delayed issuing my first bill by about 10 days after the line switch in order to increase the cancellation fee. I then submitted a written complaint, explaining that they legally cannot charge me a cancellation fee because the service is faulty. However, the response I received was mocking. The full response is shown in the image below, but I believe this particular sentence was meant to ridicule me: "Since your GSM number is a mobile line, there is no obligation to use it in a specific location." In other words, they are telling me, “You don’t have to use your phone where you are sitting—just get up and go somewhere with better reception.” I had been a Turkcell customer before, about 10 years ago, and left them for the “red company” after my internet package was consumed very quickly. I returned to Turkcell this time because I believed their claims of being better and being a domestic company—but I regret it. Especially due to the mocking tone and the fact that my complaint was not taken seriously and was answered arbitrarily, I request that my grievance be resolved.
Turkcell is a company that should not be trusted. They advertised a home portable internet plan with 250 GB for ₺635. When I signed up, my first bill was ₺700. When I inquired about this, they said it was mentioned in the contract. However, that was not communicated to me. They insisted that their s...
I ported my mobile line to Turkcell about two months ago, and since then I have been constantly experiencing serious network problems. My line almost never has proper reception, and I cannot make clear calls anywhere. People often cannot hear my voice, my calls drop, and I cannot use the line proper...
I have been seriously dissatisfied with Turkcell for about 12 days. Despite living in an earthquake zone, no improvement work has been carried out, and the network problems in our area remain unresolved. The mobile signal is weak, and the internet barely works. When we call customer service, instead...
In July 2024, I moved to Sokullu Mehmet Paşa Neighborhood, Çankaya, Ankara. (I live on the 2nd floor, in the heart of the capital.) I realized that my Turkcell line doesn’t have coverage at home, and I raised this issue with Turkcell customer service 3 times. Each time, they said the problem couldn’...
About 10 days ago, I switched from Türk Telekom to Turkcell, and my entire family also transferred their lines to Turkcell. However, at our address, we constantly experience signal problems both inside and outside the house. Despite using a 60 GB plan costing ₺420, we can barely use the internet. It...
