I have been using my Turkcell line without any issues for a long time, but since the transition to the 5G network on April 1, 2026, my line has become almost completely unusable. I am using a Samsung Galaxy A50 in the Esenyurt Kıraç area of Istanbul. Previously, the signal strength was very good, b...
Despite speaking with customer service representatives for more than three years, I am still receiving poor service with my Superbox and mobile internet connection, and it seems that no solution has been provided. The connection is often unstable and unreliable, making it difficult to use even for b...
I'd like to talk about my experience with Turkcell and their e-SIM service that I'm using. The physical SIM card in the same room connects to the internet just fine, but the e-SIM isn't working at all. Charging fees is quick and easy, but when it comes to getting service, all I get are excuses like ...
I live abroad and my line is defined as a prepaid e-SIM. Although I have a sufficient balance on my line and no debt, I will be unable to use it for about a month. Although I have switched my phone off and on many times, I can neither make calls nor receive SMS. In addition, the ‘No Service’ warning...
Thinking it was the best option, I switched to Turkcell from another operator I previously thought wasn't that great. I wish I hadn’t. The service is terrible. I have no signal at all. My previous operator was actually fantastic. They offered plenty of bonuses and I never had any issues with recepti...
In a place like Demetevler in Yenimahalle, Ankara, I can't get any signal or internet inside my shop. I called twice and reported the issue—they said they would provide support. However, I later received a negative response via message. I'm a Platinum customer and have been using Turkcell for years,...
The new line I bought for my 8-year-old child's smart watch was used, supposedly a line that had been disconnected a year ago. Not only do they fail to mention this, they also claim the new number they'll give me is a number that has been previously disconnected. Strangers are calling my child, and ...
I live in Tokat/Turhal, right in the city center. However, neither Instagram nor Youtube.com works with my Turkcell line. I have to wait 2 minutes for the page to open. It has become almost impossible to watch videos, send messages or even use the internet. Unbelievable, but I even had a hard time a...
On June 18, 2025, after my internet connection was cut off, a technician directed by Turkcell replaced my modem with a Wi-Fi 6 model for an additional fee, but he stated that the real issue could only be resolved by changing the cable. Despite calling Turkcell multiple times, it wasn’t until June 25...
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...
For the past six months, my phone hasn’t had any signal anywhere—neither at home nor outside—even though I’m in the heart of Istanbul and using Turkcell. I suspect something happened to a nearby cell tower and it hasn’t been replaced since. Everyone I talk to is experiencing the same issue. It’s inc...
I have been experiencing internet and signal outages for about two weeks through my Turkcell Superbox and Turkcell mobile line. Customer service acknowledged the outage and said it would be resolved. I was told I could report the issue through the Turkcell Assistant in the app, but nothing has chang...
When someone tries to call me while I’m on the phone using my Turkcell line, they constantly get a busy signal and the call doesn’t come through to me. In the call forwarding settings, the number 0539*****27 appears and cannot be deleted under any circumstance. I’ve tried resetting the settings myse...
I am experiencing a serious issue when calling certain mobile numbers and my home landline using my Turkcell line. When I initiate the call, there is no ringback tone on the recipient’s side, and even if they answer, there is no voice communication. This situation makes it impossible for me to reach...
I watched Turkcell’s Dronecell commercial with genuine hope, thinking it represented a real technological advancement that could help in times of crisis. But now I’m asking myself—where are those drones? Was this just another flashy ad campaign with no real-world application? Every time there’s even...
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 consta...
Dear Turkcell Representatives, In March 2025, I traveled to Spain to fulfill an international education and cultural representation duty granted to me with the approval of the Turkish Ministry of National Education. To avoid any connectivity issues abroad, I purchased an international internet pack...
I reside in the heart of Adana, and my Turkcell internet is hardly functional—it has a tough time loading even the simplest pages or apps, as if it's only managing one or two bars at best. This issue has persisted for a considerable duration, and I’ve exhausted all possible solutions on my part to r...
Eight months ago, I got Turkcell Superbox in my Izmir home (5th floor, central location), supplementing my Türk Telekom internet for online work. The technician was helpful, but the device was used, dirty. Despite this, we've had constant internet reception issues, contacting customer service ~10 ti...
On February 28, I transferred my eSIM line from Türk Telekom to Turkcell. At first, there was no network, and they told me to call Information and Communication Technologies Authority (ICTA). We called ICTA, and it turned out the line was already active, so the network appeared. Everything seemed fi...
After upgrading my mobile signature, I received my new 128K mobile signature-compatible SIM card on February 10th. On February 11th, Turkcell called me and said, "Your new SIM card has been activated. Please insert it into your phone, and you may start using it." However, I am not getting any signal...
I have been a Turkcell user for years, I had no problems until the end of December and was using it very well, in order to benefit from the campaign, I went to a different operator for my 2 lines at the end of December and came back to Turkcell without even a week, I have been having network problem...
I live in Pendik, Istanbul, in a detached house located on the coastal road in a central area with 5-star hotels just 100-200 meters away. Despite this, my Turkcell mobile line barely gets 1 bar inside the house and 2 bars in the garden. At times, I am completely unreachable inside the house, and co...
Hello, I contacted Turkcell's customer service to transfer my number to their network. During the call, I progressed to the approval stage of the number transfer process. However, I asked a question about how the termination fee would be calculated if I canceled my contract due to poor signal streng...
