T2 Mobile Operator Launches VoWiFi Support in Four Regions of Russia

The mobile operator T2, owned by Rostelecom, has launched support for VoWiFi technology in four regions of Russia, enabling users to make calls over Wi-Fi networks. This feature is currently available to subscribers in Moscow, Saint Petersburg, Tambov Oblast, and Stavropol Krai. T2 plans to expand this technology to all regions where it operates in the coming months.

According to the news agency Interfax, 6 million calls have been made over Wi-Fi in the connected regions since the beginning of March 2025, with 3.5 million of those occurring in Moscow in the last two weeks alone.

VoWiFi allows the use of standard Wi-Fi networks for calls when mobile coverage is unavailable. This option is particularly useful in basements, on upper floors of buildings, or during trips abroad. It connects to the internet through a router.

Calls made via VoWiFi are charged as regular voice traffic, so no additional fees are applied for the service, as clarified by T2.

Last year, Tele2 underwent a rebranding and changed its name to T2, opting not to renew the licensing agreement for the use of the Tele2 trademark with its Swedish counterpart, Tele2 AB.

Other Russian telecom operators, such as MTS, MegaFon, and Beeline, also offer VoWiFi services.
