Modern public transport is increasingly equipped with internet access points, but these are often paid or partially free services with intrusive advertising. Many users encounter a situation where their smartphone automatically connects to the network. metro_wi-fi or Moscow_Free, requiring authorization or payment. This not only drains battery life with constant connection attempts but can also be unsafe for personal data.
The solution to this problem lies in properly configuring your device's wireless settings. Disabling automatic connection This is the first and most important step to prevent undetected switching from mobile data to a dubious network. In this article, we'll cover the technical aspects of setting up Android and iOS so you can fully control what your device connects to.
Don't ignore this issue, as open networks on public transportation are a favorite spot for cybercriminals. Properly setting up your phone will not only save you money but also protect your personal information from interception. We'll cover specific steps for different operating systems and explain why simple settings menu actions are so important.
Reasons for automatic connection and risks of use
The main reason for the imposition of paid networks is the aggressive marketing policies of providers and the default settings of smartphones. Operating systems strive to provide the user with internet access in any way possible, so the function auto-connection Often enabled for all open networks, the phone "sees" a familiar SSID (network name) and attempts to establish a connection without the owner's knowledge.
Using such networks in the metro carries serious security risks. Since traffic on public Wi-Fi is often unencrypted or uses weak security protocols, attackers can intercept transmitted data. This is especially dangerous when logging into banking apps or sending confidential messages via messaging apps.
Furthermore, constant pop-ups asking to pay for access or view ads are annoying and distracting. The smartphone may periodically lose connection due to a poor signal in the tunnel, prompting a new authorization request each time. This creates the illusion of instability in the device itself, although the problem lies precisely in the network settings.
⚠️ Important: Do not enter bank card details on public transport login pages unless you are sure the connection is secure. It is better to use 4G/5G mobile internet for financial transactions.
Understanding the mechanism of work Wi-Fi Assist and similar features help you manage your connections consciously. These services are designed to improve the user experience, but in metro environments, they often work against the user, relying on a weak paid signal instead of a stable mobile internet connection.
Setting up a shutdown on Android: Step-by-step instructions
In Android, the process of managing networks may differ depending on the OS version and manufacturer (Samsung, Xiaomi, Pixel). However, the basic principle remains the same: find a saved network and disable automatic connection. To get started, open Settings → Connections → Wi-Fi.
Find the name of the metro provider in the list of available networks (for example, Moscow_WiFi or MT_Free). Tap it and select "Forget" or "Delete Network." This action erases the connection profile from your phone's memory. After this, even when in range, your phone will not attempt to connect.
For more advanced settings, go to the advanced Wi-Fi settings. Here you can disable the "Connect to open networks" feature. Some manufacturers add a separate "Auto-connect" switch that needs to be toggled off for each access point.
☑️ Check Android settings
It's also important to check your date and time settings, as out-of-sync can cause authentication errors or, conversely, block access to legitimate resources, forcing your phone to look for alternatives. Make sure automatic syncing is enabled.
Managing networks on iPhone (iOS)
Apple device owners should also closely monitor the list of known networks. In iOS, this is controlled through the menu. Settings → Wi-FiClick on the blue information icon (i) Next to the metro network name. In the menu that opens, toggle the "Auto-connect" switch to the off position.
If a network is already saved and causing problems, the best solution is to completely delete the profile. To do this, select "Forget This Network" in the same information menu. Confirm the action, and your iPhone will no longer see this access point as a priority. This is especially true for networks that require periodic identity verification.
Function Wi-Fi Assist In iOS, this can create the false impression that the phone is using mobile data, even though it's trying to balance the load. Disable it in the menu. Settings → Cellular (at the very bottom of the list) to ensure that if your Wi-Fi is poor, your phone won't try to use its background processes.
Secrets to resetting iOS network settings
If deleting the network doesn't help, you can perform a full network reset. This will delete all Wi-Fi passwords and Bluetooth settings, but it often resolves stuck connection issues. Go to Settings → General → Transfer or reset iPhone → Reset → Reset Network Settings.
Keep in mind that iOS strictly enforces security certificates. If a metro network requires a root certificate to be installed, that's a red flag. In this case, it's best not to connect at all, as this allows your ISP to analyze your traffic.
Table: Comparison of shutdown methods
To help you compare different approaches to solving this problem, we've prepared a summary table. It will help you choose the most appropriate method based on your operating system and desired level of control.
| Method | Android | iOS (iPhone) | Efficiency |
|---|---|---|---|
| Forget the network | Long press → Forget | Click on (i) → Forget | High |
| Disabling auto-connection | In the network properties | 'Auto-connect' toggle switch | Average |
| Reset network settings | System Preferences | General → Reset | Maximum |
| Blocking via router | Not applicable | Not applicable | Low (for public) |
As the table shows, the "Forget Network" method is the most versatile and effective for most users. It doesn't require extensive technical knowledge and quickly achieves the desired result.
Using more complex methods, such as a factory reset, is only justified in cases where the phone behaves incorrectly or constantly freezes when trying to connect to certain access points.
Clearing certificates and hidden profiles
Sometimes simply deleting the network is not enough, as there may be remaining networks in the system. safety certificates, issued by the Wi-Fi provider. These certificates allow traffic decryption (Man-in-the-Middle attacks). On Android, the path to them is usually in Settings → Security → Encryption & Credentials → Trusted Credentials.
In the list of certificates, look for names associated with the Metro provider or organizations you don't recognize. If you find a certificate that was recently installed or raises suspicions, you should remove it. On iPhone, certificate management is located in Settings → General → About → Certificates (at the bottom of the list).
Removing questionable profiles is an important digital hygiene measure. These profiles are often installed automatically the first time you access the login page through your browser. If you don't remember installing such a certificate, it's a sure sign that it needs to be removed.
Regularly checking this menu section will help maintain your smartphone's security. Prevent unnecessary digital "keys" from accumulating in your device's memory.
Block ads and pop-ups
Even after disabling auto-connect, some apps or browsers may still try to open your ISP's website. To combat this, you can use ad blockers or change your DNS servers. Setting up an ad-blocking DNS (e.g., 1.1.1.3 (from Cloudflare) helps filter requests to known advertising domains.
On Android 9 and above, you can use the "Private DNS" feature. Enter the address dns.adguard.com in the appropriate field in your Wi-Fi or connection settings. This will block most intrusive banners and redirects to payment pages.
On iOS, this feature is available in the section Settings → Wi-Fi → (i) next to the network → DNS ConfigurationSwitch the mode to "Manual" and add servers with filtering. This will not only remove ads but also speed up page loading by optimizing routing.
⚠️ Note: Using third-party DNS servers may affect the operation of some local services or corporate networks. If you notice problems accessing certain websites, reset your DNS settings to automatic.
This approach creates an additional layer of protection and convenience. Not only do you eliminate paid Wi-Fi, but you also make your internet experience cleaner and safer.
Frequently Asked Questions (FAQ)
Can a Wi-Fi outage in the metro affect the operation of the navigation system?
No, navigation apps (Yandex.Maps, Google Maps, 2GIS) use GPS/GLONASS modules and mobile data to plot routes. Disabling Wi-Fi will not affect positioning accuracy and, in some cases, may even improve performance, as the phone will stop scanning the air for available networks.
Will my phone use more battery if I don't turn off auto-connect?
Yes, constantly searching for networks, attempting to connect, and checking for the availability of the sign-in portal in the background can significantly increase battery consumption. Disabling this feature will extend your device's battery life while on the go.
What should I do if the 'metro_free' network reconnects automatically after a reboot?
This could be a sign of malware or a deeply embedded carrier profile. Try resetting your network settings. If the problem persists, check your installed apps for any unknown programs that may have network management permissions.
Is it safe to use a VPN when connected to paid Wi-Fi?
Using a VPN significantly improves security by encrypting all traffic between your device and the server. However, if the network requires browser authentication, a VPN may prevent the login page from displaying. Enable the VPN only after successful authentication or use mobile data.
How can I find out how much money was charged for the connection?
Providers typically send SMS notifications before debiting funds or when you activate the service. Read the pop-up messages carefully. You can also check charges in your mobile operator's personal account or through a service request (USSD code) available on the Wi-Fi provider's website.
