On October 13, 2025, an incorrect charge of 3,420₺ was applied to my Turkcell postpaid line, and my line was subsequently disconnected.

On October 10, 2025, on my Turkcell postpaid line, it was reported that I used about 12 GB of internet in total — 3 GB around 12:00 p.m. and 9 GB around 1:45 p.m., on the same day my package was renewed. However, it is impossible for me to use such a large amount of data in such a short time through...
Without my permission, Turkcell renewed my contract and raised the price by 150₺. They wouldn't cancel it when I contacted to tell them about it. I don't get how a business can act this way after I made it plain that I didn't want the renewal. Their customer service makes it seem like they don't car...
I was using the Turkcell Superbox 200 GB package. About five months ago, I was informed of a ₺12,000 penalty, which I paid. After making the payment, I contacted customer service and was told that all my debts had been cleared. However, today I received another penalty message for ₺2,800, with no ex...
I recently switched my mobile number +90 532 505 ** 55 from Vodafone to Turkcell — and I already regret it. During a short trip abroad, I made two very short calls, together less than one minute in total. That’s it. Yet Turkcell automatically activated a “daily roaming package” priced at ₺350 per da...

On July 31, 2025, I was informed by Turkcell customer service that if I transfer my mobile line to another operator, I would be charged an early termination fee of ₺2,500.

In my Turkcell subscription with the number 0539*****47, I discovered by chance on e-Government that I had a debt of ₺5,030 from August 2023, only two years later. During this period, I was never informed by SMS, call, or mail. After the debt came to light, I contacted both Turkcell customer service...
I am a Turkcell postpaid line user. At a Turkcell store in Samandıra, Sancaktepe, Istanbul, I noticed that they were offering the same tariff I use to new customers for ₺420, while as an existing customer I am forced to pay ₺540 for the same plan. I realized this situation about 10 days ago. My tari...
On September 20, 2025, I switched to a postpaid line through number portability at a Turkcell store in Sındırgı, Balıkesir.

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.

11 days ago, I requested a SIM card from Turkcell for a postpaid line under the 20 GB campaign, but during this time my SIM card has not been delivered to my address. I called customer service many times about the issue, and each time I was told it would be delivered within a few days, yet my SIM ca...
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 canceled my Turkcell postpaid line on August 4, 2024, and paid all my outstanding debts. Despite this, after the cancellation of my line, a new bill of ₺208 was issued for the August 2024 period.

I have been a Turkcell postpaid customer for about a year, and although I have a 60 GB internet package, it runs out very quickly. In recent months, my data has been completely consumed within just 13 days. Yet during the day, I use my company’s internet at work and my own Wi-Fi at home. Even the bo...

I have been dealing with this issue for a week, and when I contacted customer serv...
I have visited six different Turkcell stores in the Büyükçekmece and Beylikdüzü districts of Istanbul over the past week to obtain the twin SIM card service promoted on Turkcell’s official website. However, every store informed me that they do not have twin SIM cards available, and as a result, I wa...
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.
