Some megaphone subscribers on parts of sites opened from the phone see an additional banner for the entire screen. He appears even where such advertising is not provided - for example, in the service for publishing Telegraph texts belonging to the Telegram messenger.
Banners inserts MegaFon. The operator intervenes only in the code of sites working on an unsafe http protocol - unlike encrypted HTTPS, in it the provider sees the entire contents of the transmitted data and can change it.
Messages about the intervention of Megafon have appeared in the traffic of users earlier , but recently there have been especially many complaints. The company "Medusa" said: “This possibility of posting information works in test mode. With specific complaints, our clients can contact the contact center. ”
In social networks, representatives of the operator also advise contacting the subscriber service - there they will connect a free service prohibiting the advertising show. This also works when contacting the company through social networks. It was not possible to find the ability to independently abandon such banners “Medusa” in the mobile iOS application of MegaFon.
Mobile subscriptions
MegaFon cites several thousand Internet addresses, when entering users risk ordering “mobile subscriptions”-each day several (dozens) rubles are written off from the account in exchange for providing access to such a site. Many users agree to such subscriptions out of ignorance, but understand that something is wrong, only noticing the write-off from the account.
To see what you are signed for and refuse subscriptions, you need to go to the Moy-m-portal.ru/moi_podpiski page from the phone via mobile Internet (this is the Megafon website, here's the proof ).

Medusa failed to find mentions of intervention in traffic from MTS.
It is very easy to accidentally subscribe to a site with paid content in MTS. Moreover, the page often looks like an inattentive user does not even know when he agreed to the service.
To find out if you are connected by paid services and disconnect them, you need to open the site moicontent.mts.ru or dial on the phone number *152 *2#.
In addition, one of the subscribers of MTS wrote instructions for blocking access to the page through which subscriptions are carried out. This is done in the iPhone settings, you can add any address to the black list. The path is this:

Complaints that Beeline intervenes in the traffic of subscribers (both through home and mobile Internet) sounded in 2014 , 2015 and 2016 . But each time it was not about embedding advertising, like a Megafon, but about adding a button that led to a “mini-cabinet” -a page on which you can find out your balance and other information.
In December 2016, Beeline announced the closure of the “mini-cabinet”.
Mobile subscriptions
In the summer of 2014, representatives of Beeline stated that he seriously revised the mechanism for working with paid subscriptions and paid content services. The company claims that no subscription can be activated without confirmation, but immediately admits that pressing the link in the browser is considered such a confirmation.
To see the list of connected services, you need to go to your personal account on the Beeline website and find the section “My Information and Entertaining Services” in the profile tab. Subscriptions are listed in the mobile application of Beeline.
To protect yourself from any intervention in your Internet traffic, you will have to sit through the VPN or use only sites working on the HTTPS protocol.
In order to not write off the money for access to the content from your account, connect a separate personal account for your operator for content services. For some companies, this is done in your personal account, others will have to contact the communication salon. Read more about connecting the second account from each operator was told by our colleagues from vc.ru.
