==Controversies==
=== Removing Discounts for Those Who Turn Off Data Collection ===
Users who choose to opt out of Turkcell's data collection practices through the Turkcell mobile app will no longer be able to view time-limited offers, which frequently include service discounts. Turkcell offers free mobile data usage for a month to users who consent to data collection after initially rejecting it. If the data collection is rejected once more, the free data usage will be terminated. Because they have already consented, users who consent to data collection first do not receive any rewards.
===PPPoE/WAN Password Restrictions===

Turkcell Superonline does not disclose the PPPoE/WAN username and password of its users. This restricts the freedom of users to use their own modems instead of the modems rented to them by Superonline. Although some users try to obtain this password through various methods, it is reported to be very difficult or impossible to obtain, especially for some modem models (e.g. HG255s). It is stated by users that even if the PPPoE username and password are known, the internet service provider (ISP) must register the MAC address of the new modem in its system, otherwise the modem cannot be used. This can be bypassed by cloning rented modems MAC addresses.<ref>[https://openwrt.org/docs/guide-user/network/wan/isp-configurations OpenWrt Wiki - ISP Configurations]</ref>
===Disabling Root Accounts and Firmware Restrictions===

Turkcell Superonline's decision to restrict or completely disable access to the root account on the modems it rents to its users has sparked controversy among users. Superonline does not allow the use of third party modems. The firmware of the modems provided by Superonline is often customized and restricted, preventing users from gaining root access via web interface, telnet or ssh. One of the main reasons for this is that modem firmware updates and management are centralized by Superonline. It is argued that this centralized management may become more difficult if users have root access. While some users have stated that they need root access to configure their modem's settings in more detail (for example QoS and Easy Setup features are removed from modem interface), to install alternative firmware (like OpenWRT or Asus Merlin Firmware), or to enable/disable certain features, they have encountered this restriction by Superonline. In particular, some modem models are reported to disable features such as backups and manual updates via files in order to make it more difficult to obtain the root password. Some modem models have also been reported to disable the ability to change the main DNS server.<ref>[https://wf.lavatech.top/ave/router-misadventures Router Misadventures: Dumping Superonline's ISP Fiber Router]</ref>
===Censorship Using Deep Packet Inspection===
Superonline is one of the most active utilizers of deep packet inspection (DPI) technology among internet service providers in Turkey, operating within a regulatory environment that Freedom House describes as systematically restricting online freedoms.<ref>{{cite web |url=https://freedomhouse.org/country/turkey/freedom-net/2023 |title=Turkey: Freedom on the Net 2023 |website=Freedom House |publisher=Freedom House |date=10 October 2023 |access-date=3 June 2025}}</ref> With this technology, Superonline applies content-based censorship by analyzing users' internet traffic in detail.<ref>{{cite web |url=https://freedomhouse.org/country/turkey |title=Turkey Overview |website=Freedom House |publisher=Freedom House |date=31 March 2025 |access-date=3 June 2025}}</ref>

Unlike traditional packet inspection, DPI technology also scans the content of data packets and provides the ability to detect and block VPN protocols. According to user reports, Superonline has one of the most strictly censored internet service in Turkey, and in the past has taken measures strict enough to completely block VPN protocols such as WireGuard. It also blocks or throttles popular VPN services and their websites such as Cloudflare Warp, ProtonVPN, Surfshark, Psiphon, NordVPN, IPVanish/SpeedtestVPN and constantly tightens its DPI-based scanning systems. There is also allegations that Superonline using DNS poisoning to block certain websites. They were blocking some third party DNS services in the past.
