Approximately three weeks ago, I purchased a new SIM card from Turkcell as my old SIM card was defective. I paid a fee for the replacement. However, once I switched to the new SIM card, my mobile signature subscription was cancelled without my consent. On September 4, 2025, I attempted to reapply fo...
On August 31, I applied online to transfer my line to Turkcell and requested an eSIM. I installed the eSIM on my phone, but when trying to activate it through e-Devlet, I repeatedly encounter a 'MERNIS' error. I visited a Turkcell store and also contacted customer service, but no solution was provid...
Yesterday, I went to the Turkcell Özkanlar branch in Bayraklı, İzmir, to activate an eSIM for my Motorola Edge 50 Neo device. However, even though the eSIM activation was not completed, ₺160 was charged to my credit card and my phone remained without service. During this process, I contacted both BT...
I have been a Turkcell postpaid customer for about 20 years, currently using the Mega+20GB package for which I pay ₺420 per month excluding taxes. The package includes 1000 minutes of talk time. However, new subscribers are offered the exact same package at much lower prices—for example, a new custo...
Two years ago, I started with a 20 GB + 20 GB social media plan for ₺200, which was increased to ₺440 in the second year, and now as my contract is about to expire this year, I was offered a price of ₺660. Despite repeatedly explaining that I was abroad, unable to make changes, and requesting a disc...
About three months ago, I ported my number from Vodafone to Turkcell. However, for the past two months, I have been facing a serious issue: when people using Vodafone lines try to call me, they hear a message saying “This number does not exist” and cannot reach me. As a result, I am missing importan...
I am using Turkcell, and my contract is about to expire, but the 15GB plan I have costs ₺500, while Türk Telekom offers a 40GB plan for ₺490. This price difference is completely unfair and makes me feel undervalued as a loyal customer. I have been paying my bills on time every month and expected to ...
I am using the Surprise Extra 10 GB plan on my Turkcell postpaid line. My contract expires on September 20, 2025. When I want to renew my contract, I am charged 360₺ for the Full Extra 10 GB package. However, customers who switch carriers or get a new line are offered the Big Festival 10 GB package ...
I was using a 50 GB package with a 12-month commitment on my Turkcell postpaid line 0554*****12. My commitment was supposed to end on 09.08.2025, but on 08.08.2025 at 14:40, I switched to another operator. Following this, I was billed a total of ₺1300.59, which included a ₺650.05 early termination f...
In April, I was contacted by the Turkcell finance department and informed that a loan of ₺66,000 had been taken out in my name using my Turkish ID number. Previously, a device had also been issued in my name without my consent. My line is currently being actively used. Despite repeatedly contacting ...
My mother voluntarily initiated the cancellation of the Superbox 200GB package at the Turkcell branch in Dikili, İzmir, and signed the necessary documents. She was born in 1959, which means she is over 65 years old. However, she was asked to return the device to another branch in Karşıyaka, İzmir. S...
"My issue was resolved by being reflected on the bill, albeit late. The full amount was not refunded, but most of it was, and I did not consider the remaining part significant."
On the invoice issued on August 10, 2025, for my Turkcell postpaid data line, the full amount of an internet package I did not use was charged to my p...
Between 01.08.2025 and 09.08.2025, I was in Naples, Italy, and Zagreb, Croatia. During this period, I used an eSIM instead of my Turkcell postpaid line (05366307***), yet Turkcell claims my line received a signal for 4 days with a very low data usage of about 0.2 MB per day and charged me an additio...
On Tuesday, August 12, I applied online to transfer my number to Turkcell and requested it as an eSIM. On Thursday, August 14, at 10:45 a.m., my number was transferred to Turkcell. However, when I tried to enter the provided eSIM information into my iPhone 16E, I received the error message: “This co...
Turkcell directed me to a company called Lena. While I can get a server service from AWS in just 5 minutes, I couldn’t get the same service from Turkcell even in a month. I have never experienced such an absurd situation in my life. Everywhere else in the world, getting a server service takes 5 minu...
When I wanted to transfer my Turkcell postpaid line to another operator, I encountered a debt issue that has remained unresolved for about a year. Last year, I was told there was a ₺27 debt, but when I went to the dealer, the debt did not appear. Despite going back and forth multiple times between c...
In April, I purchased a one-month package from Turkcell for my daughter’s prepaid line while she was visiting Turkey for a 15-day vacation from abroad. When purchasing the package, I repeatedly asked the customer representative to ensure it would not auto-renew, and I was assured it would not. I di...
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...
I am a subscriber of the Turkcell Genç Avantaj 90 GB postpaid plan, and I have been experiencing a serious issue with data usage since the first day I activated my line. The plan includes 30 GB of general internet and 60 GB for social media usage. However, even though I only use social media apps li...
Dear Sir/Madam, I'm sending this matter to you to express my indifference. I'm deeply disappointed by the negative experiences I've had with the (E-SIM) activation code. The problem I'm experiencing is that the E-SIM activation code isn't being added to the device. You call customer service and they...
Turkcell said there was no commitment, but after switching my line, they charged me ₺1400! Vodafone offers the same service at half the price! I switched my Turkcell line to Vodafone. The package I used at Turkcell cost over ₺1000 per month, and I got the same package at Vodafone for ₺512. I was tol...
I use an internet service under customer number 11545736. Although my internet speed is supposed to be 1000 Mbps, I’ve been receiving speeds as low as 400, 500, 300 Mbps, or even lower throughout the day. On July 30, 2025, at 21:47, I called customer service to report the issue, but I couldn’t reach...
Turkcell has introduced a new practice called “interim payment” and backed it with a legal provision. Dear Turkcell representatives, it feels as though instead of trying to retain loyal customers—like those who switched to you from other operators in the past and have brought you significant revenue...
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...
