Hello, I was abroad between 07.09.2024 and 11.09.2024, and I am using the Turkcell operator. Every time I travel abroad, although my line is active, the daily international usage fee has not been applied. This time, I created an e-SIM and purchased internet through an app store. For this reason, I occasionally turned off my Turkcell line and activated the other line. When I turned off the other line, my Turkcell line automatically regained signal. Upon reviewing my usage details, I saw that I was charged for a total of 4 days, amounting to ₺250 each day, solely because of this signal. When I called customer service, they said they could only deduct the charge once because the system does not allow further adjustments. They did not direct me to a different department to address this issue through email. My usage details are attached, and there was no actual usage, only minimal kilobytes being recorded.

When I noticed this, I contacted customer service, but they only acknowledged 4 seconds of usage per day, which makes no sense given that the phone was in airplane mode with no possibi...

Hello, despite being in Turkey on June 24, 2024, I was charged ₺210 for international usage on my Turkcell bill while I was in Ayvalık. I have no idea how Turkcell managed to connect to a foreign network, especially while driving. This issue occurs every year. It seems Turkcell isn't making enough m...
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...
Turkcell added over ₺400 to my bill, claiming that I exceeded my data limit eight times within just five minutes, despite not having my phone with me or actively using the internet. When I spoke to customer service, they dismissed me, saying they could not assist. The live chat support on the mobile...
