Modern urban transport is unimaginable without internet access, and the Moscow metro is no exception. However, free networks such as MT_Free or Moscow_WiFi_Free, often have time or speed limitations, after which they offer to connect paid accessSmartphone users sometimes encounter situations where their device automatically connects to a paid hotspot, which can lead to unexpected charges on their mobile account or linked card.
The most frustrating thing happens when you're deep underground, with no cellular signal but still connected to Wi-Fi. At this point, your phone may silently switch to a commercial network if you've previously approved access or saved a profile. Automatic connection — This is a convenient feature that, in the case of paid metro services, can play a nasty trick.
In this article, we'll take a detailed look at how to completely disable paid Wi-Fi in the metro, delete saved profiles, and configure your smartphone to prevent it from connecting to untrusted hotspots without your knowledge. We'll cover the settings for Android And iOS, and we will also touch upon issues of data security in public networks.
Why does my phone automatically connect to the paid metro network?
The main reason for automatic connection lies in the operating system's algorithms. Your smartphone constantly scans the airwaves for known networks. If you've connected to a metro network at least once (even to the free version) and checked the "Connect automatically" box, your phone will prioritize it as your internet source.
When the free plan (usually 30 or 60 minutes) expires, the service provider may redirect your traffic to the payment page or, in the worst case, switch to another one SSID (network name), which is already a paid plan. Network names are often very similar, and the user doesn't notice the difference until they receive an SMS notification from the operator.
Furthermore, there's a risk of network spoofing by attackers or technical failures in subway routers. In such cases, a device could become entangled in an open gateway that's formally part of the infrastructure but requires payment to continue the session.
- 📡 Saved profile: The phone remembers the network and tries to reconnect at the first opportunity, ignoring the payment status.
- 🔄 Connection priority: If the mobile internet connection is weak, the system gives preference to Wi-Fi, even if authorization is required.
- 🕸 Background processes: Applications can initiate requests to the network, causing a reconnection to the last known point.
It's important to understand that simply turning off the Wi-Fi slider in the notification shade is a temporary solution. Once you turn the module back on, your connection history will resume. This is precisely what's needed. delete or forget network in settings.
⚠️ Attention: Subway Wi-Fi charges are often not immediate, but rather are packaged or subscribed. Carefully read the terms and conditions on the login page before clicking "Renew."
How to delete a Wi-Fi network on Android
In the operating system Android The network management process may differ depending on the OS version and the manufacturer's shell (for example, Samsung One UI, Xiaomi MIUI or pure Android). However, the general principle remains the same: you need to find the list of saved networks and forcibly disconnect.
To get started, open your device's settings. Find the section Connections or Network and Internet. Here you are interested in the point Wi-FiDon't just turn it off, but go inside the menu where a list of available and saved networks is displayed.
☑️ Check Android settings
Find the network in the list with a name similar to MT_Free, Moscow_WiFi_Free or any other variations with the Metro prefix. Click on the network name or the gear icon next to it. In the menu that opens, select the option Delete or Forget the network.
If the network is currently active and connected, first press Disable, and then DeleteThis action will terminate the current connection and delete the saved password or certificate from the phone's memory. Now, even when in range, the phone will not attempt to log in.
In some cases, especially on older versions of Android, you may need to reset your network settings. To do this, go to the section System or General settings find the item Reset settings and select Reset network settings (or Reset Wi-Fi and Bluetooth). This will delete all saved Wi-Fi networks and paired Bluetooth devices, resetting the modules to factory settings.
What to do if the network is not deleted?
If the "Forget Network" button is grayed out or disappears, the network profile may be managed by a device administrator (e.g., a corporate phone) or a security certificate may be installed. In this case, check the "Security" -> "Certificates" section and remove any user certificates associated with the metro.
Disabling Automatic Connection on iPhone (iOS)
Device owners Apple You may also encounter persistent connections to paid hotspots. Network management is organized slightly differently in iOS, so it's important to be careful when selecting options in the menu.
Go to Settings -> Wi-FiYou'll see a list of networks your iPhone has connected to. Find the Metro network. If it has a blue checkmark next to it, it's connected. Tap the blue icon. (i) in the circle to the right of the network name.
In the network details menu that opens, you will see a switch Auto-connectionMake sure it's turned off (the slider is gray). However, to be absolutely sure the network won't be used, it's better to click the button Forget this network at the bottom of the screen and confirm the action.
The "Forget This Network" feature in iOS works effectively: it deletes all network data, including proxy and DNS settings if they've been changed. After this, your iPhone will no longer see this access point as trusted.
- 🍏 Reset network settings: If deleting a specific network doesn't help, you can take a more radical approach. Go to
Main->Transfer or reset iPhone->Reset->Reset network settings. - 📶 Airplane mode: Often used as a temporary solution on the subway, turn on Airplane Mode, and then separately enable Wi-Fi only if you really need it for other purposes.
- 🔒 Private Wi-Fi address: iOS 14 and later have a private MAC address feature enabled. This improves security, but in rare cases can conflict with port authorizations in the Metro.
Table: Comparison of Wi-Fi Disabling Methods
For clarity, we'll compare various methods for disabling paid access. This will help you choose the best option based on your situation and smartphone model.
| Method | Efficiency | Complexity | Consequences |
|---|---|---|---|
| Turning off the Wi-Fi slider | Low (temporarily) | Minimum | No connection at all until you turn it on again. |
| Disabling Auto-Connect | Average | Low | The network is visible, but it doesn't connect itself. |
| Forget a network | High | Low | Complete profile deletion, new authorization required |
| Reset network settings | Maximum | High | Delete ALL saved Wi-Fi and Bluetooth pairs |
As the table shows, the most sensible step is to remove the network from the list of saved networks. This doesn't affect other phone settings, but it's guaranteed to prevent unwanted connections.
Resetting network settings should only be done if you suspect that errors or "junk" profiles have accumulated in the system that are interfering with the normal operation of the communication module.
Data security in public transport
Disabling paid Wi-Fi isn't just a matter of saving money, but also a matter of digital hygiene. Public networks, especially in heavily trafficked areas like the subway, are a prime target for hackers.
When you connect to an open network or a port-based network (via a browser), your traffic is often unencrypted between your phone and the access point. Attackers can use methods MITM (Man-in-the-Middle) to intercept data.
Even if a network requires payment, it doesn't guarantee its security. The payment gateway may be protected, but other traffic after authorization often remains vulnerable. Therefore, if internet access on the subway is critical for you, it's better to rely on your mobile 4G/5G or use VPN services.
⚠️ Attention: Never enter bank card details, passwords for important accounts, or make payments while on a public Wi-Fi network without a VPN enabled.
Phishing pages are also worth mentioning. Attackers can create an access point with a name identical to the official metro network (for example, MT_Free_Update). After connecting, the user is taken to a fake payment page, where they may accidentally enter their card details.
What to do if the money has already been written off
If you notice a charge for Wi-Fi in the metro, don't panic. Telecom operators and service providers are often accommodating, especially if the complaint is received promptly.
First, check your balance and connection history. Typically, after a charge, you'll receive an SMS with an access code and instructions. This message often also includes a short number or website where you can request a service deactivation and refund.
Contact your mobile carrier's technical support. Let them know that the connection was automatic or accidental, and that you didn't intend to use the paid plan. In most cases, if your traffic was low, the carrier may cancel the payment as an exception.
- 📞 Call the operator: Call the toll-free support number (even if your balance is zero).
- 💬 Chat in the app: Contact support through the operator's official app—it's faster and preserves your chat history.
- 🚫 Blocking: Ask to block the connection of paid content services, if such an option is available.
Please remember that refunds are typically only available within a short period (e.g., 24 hours) after service activation. Therefore, it's important to regularly monitor your account balance.
Is it possible to permanently block paid Wi-Fi networks?
Completely blocking connections to specific SSIDs at the system level is impossible without root access or special configuration profiles (MDM). However, removing the network from the "Known Networks" list and disabling auto-connection will minimize the risk. There are also firewall apps that can block connections to open networks, but they require complex configuration.
Do they charge money to access the authorization page?
Accessing the captive portal is usually free. Your account is only charged after you've entered your phone number, received an SMS, and confirmed your login, or if you've previously agreed to automatic renewal. However, be careful: some fraudulent sites may mimic the login page.
Why is Wi-Fi slow in the metro?
Low speeds are due to the high load on communication channels. During rush hour, hundreds of passengers can connect to a single access point. Furthermore, tunnel walls and the design of train cars interfere with the radio signal. A paid tariff often (but not always) provides priority in the traffic queue, but this does not increase the physical bandwidth.
How to check if your phone is connected to someone else's network?
Pay attention to the Wi-Fi icon in the status bar. If you haven't turned on Wi-Fi and it appears, that's a warning sign. You can also check the network name in the settings: if it says "No Internet Access" or an unfamiliar name, disconnect immediately and delete the profile.
