The mobile operator Kyivstar announces the purposeful destruction of its own infrastructure by the Russian military.

"Friends, right now the enemy is deliberately destroying the infrastructure in Mariupol. Our technical heroes will try to restore communication as soon as possible," the operator's Facebook page says.

Kyivstar also reminded that national roaming operates throughout Ukraine, and if the connection of one operator disappears, the subscriber will be able to connect to another operator manually by disabling the "automatic network selection" function.
