Commuting on public transportation in a large city often takes up a significant portion of the day, and a lack of internet access in the subway can turn this time into a complete waste of time. Fortunately, the Moscow Metro has had a free internet access system in place for several years now, covering almost all stations and trains. This allows passengers to watch movies, listen to music, check work email, or simply scroll through their news feed without using up their mobile data plan.
However, the process of connecting to the network MT_Free (as the official network is called) isn't always a smooth process, especially for those new to the service or who've changed devices. There are various authorization methods, depending on your carrier, smartphone model, and current system security settings. In this article, we'll cover all the login methods, possible errors, and troubleshooting steps to ensure you stay online even 80 meters underground.
Network search and initial connection
The first step to accessing the internet is finding a signal. When you're on the platform or in a train car, open your device's Wi-Fi settings. In the list of available networks, find MT_FreeIt's important not to confuse it with similar names offered by third-party services or advertising networks unrelated to the metro. After selecting the network, click the "Connect" button.
In most cases, the system will automatically redirect you to the authorization page. This is achieved through Captive Portal technology. If the automatic redirection doesn't occur and you see the message "Connected, no internet access," try opening any browser and visiting any website, such as ya.ru or google.comThe browser should force the login window to open.
It's worth keeping in mind that during rush hour, when carriages are overcrowded, connection speeds can be unstable due to the high load on the equipment. The signal can also drop out in tunnels between stations, although modern trains are equipped with repeaters that minimize connection interruptions.
Methods of authorization in the system
After the login page loads, the user is prompted to select a convenient identity verification method. Metropolitan Wi-Fi supports multiple protocols, allowing it to accommodate users with varying preferences and technical capabilities. The primary methods are login via social media, phone number, or SMS.
The fastest way for many users is to log in via social media. The system supports popular platforms such as VKontakte, Odnoklassniki, and others. When choosing this method, you simply need to click the appropriate button and allow the app access to basic profile data. This action confirms you are a real person, and access is granted automatically.
An alternative option is to enter your mobile phone number. Be careful here: the number must be valid, as you may receive a confirmation code or a notification of successful authorization. This method is often used if you don't want to link your social media accounts to public networks.
- 📱 VKontakte: The most popular method among young people, it requires an installed application or logging in via a browser.
- 📞 By phone number: a universal method that works even on push-button phones with WAP support (although modern smartphones use a full-fledged browser).
- 📲 Via SMS: The classic method requires a SIM card with a balance or a tariff that includes incoming messages.
- 🆔 State Services (Mos.ru): An option for those who prefer to use government IDs to access city services.
⚠️ Attention: By logging in via social media, you grant the network operator access to your public profile. If you're concerned about privacy, use the phone number authentication method.
Authorization for subscribers of the "big four"
The automatic authorization feature for subscribers of Russia's largest mobile operators (MTS, Beeline, Megafon, Tele2) deserves special attention. If your SIM card is registered with one of these networks, the login process can be significantly simplified or even eliminate the need for passwords. The system identifies the operator by IP address or SIM card information (depending on the connection method).
To use this feature, you must select your operator's logo on the authorization page. The system will then send a number verification request. In some cases, confirmation may be required via a pop-up window or a reply SMS, which is often free. This depends on your current roaming settings and partner agreements.
If automatic login doesn't work, check if your smartphone is blocking pop-ups or if "Data Saver" mode is enabled, which could prevent requests from being redirected correctly. Also, make sure your device's mobile data is temporarily enabled for the initial verification, even if you're connected to Wi-Fi.
Setting up Android and iOS for stable operation
Android and iOS operating systems handle connections to public networks differently, which can cause difficulties. On Apple devices (iPhone, iPad), a common situation is that the authorization page doesn't appear automatically. In this case, you need to manually go to the Wi-Fi settings and tap the icon (i) next to the network name MT_Free and disable the "Auto-connect" option, then connect again.
On Android devices, problems are often related to the security protocol. Modern versions of Android can block connections if they deem the network unsafe. It's also worth checking if "Randomized MAC Address" mode is enabled, as some authentication servers may treat it as a new device each time, requiring you to re-enter your credentials.
To improve connection stability, we recommend selecting the "Forget Network" option for MT_Free in the Wi-Fi settings if you've previously encountered connection errors. This will clear the cache of old settings and allow the device to obtain a fresh IP address and correctly handle the redirection to the authorization portal.

Solving common access problems
Even with the correct settings, users may encounter connection errors. One of the most common issues is the "Infinite Loading" login page. This often occurs because DNS servers cannot resolve the portal name. In this case, manually entering the DNS address can help, for example, 8.8.8.8 (Google) or 1.1.1.1 (Cloudflare), although on public networks this may be blocked by administrators.
Another common situation is the message "Incorrect password" or "Retries exceeded." This may mean that your phone number or account has been temporarily blocked by the security system due to suspicious activity or excessive reconnections. In this case, you should wait 15-30 minutes before trying again.
If you use VPN or ad-blocking apps (AdGuard and similar), they can interfere with the Captive Portal mechanism. These programs attempt to encrypt traffic or filter requests before authorization, making network access impossible. It's best to disable such services while using the subway.
⚠️ Attention: Technical parameters of the network, including authorization portal addresses and supported protocols, are subject to change by the metro administration without prior notice. If standard methods stop working, check the information desks in station lobbies for current instructions.
Data security on the public network
Using open Wi-Fi networks, even those as large and secure as those in the Moscow metro, always carries certain risks. Although traffic within the metro network is monitored, the theoretical possibility of data interception (a Man-in-the-Middle attack) exists. Attackers can create fake access points with similar names, for example, MT_Free_5G or Metro_WiFito take possession of your data.
To minimize risks, never conduct financial transactions (online banking, entering card details) or enter passwords for important services while on a public network unless you have a secure connection enabled. VPN-connections. After ending your internet session, it's recommended to click the "Forget Network" button in the Wi-Fi settings to prevent your device from automatically connecting to it in the future without your knowledge.
It's also worth paying attention to the permissions you grant during authorization. If the network requests access to contacts, geolocation, or microphone under the guise of "user verification," this is a warning sign. The official MT_Free authorization system typically only requires verification of a phone number or social media profile.
What should you do if you entered your bank password on a public network?
If you accidentally entered sensitive data on a public network without a VPN, immediately change your passwords for important services (bank, email, social media) using mobile data or another trusted network. It's also a good idea to check your transaction history for unauthorized access.
Network specifications and limitations
The metro's Wi-Fi network is designed primarily for comfortable surfing, watching videos, and listening to music. However, like any public infrastructure, it has its technical limitations. Connection speeds may vary depending on the time of day, station congestion, and the number of simultaneous users in the car.
Network administration may impose restrictions on the use of certain protocols, such as P2P (torrents), or block access to resources that violate Russian law. Session time limits also exist: after a certain period of continuous use (usually several hours), the system may require re-authorization.
The table below shows the main parameters you can expect when connecting to the metro network:
| Parameter | Expected value | Note |
|---|---|---|
| Frequency range | 2.4 GHz / 5 GHz | Depends on the station equipment |
| Average speed | 5–20 Mbps | During rush hours, speed may drop |
| Ping (Latency) | 40–100 ms | Not recommended for online gaming |
| Traffic limit | Unlimited | Session time restrictions apply. |
| Protocols | WPA2-Enterprise | Used to encrypt traffic |
