The Ministry of Digital Transformation advises Ukrainians to immediately contact the mobile operator in the contact center if the invaders took away the phone and a SIM card.

"If the invaders have taken your phone and SIM card, immediately inform your mobile operator at the contact center: Vodafone - 111, Kyivstar - 466 and lifecell - 5433," the message says.

Thus, the numbers will be blocked and the invaders will not be able to use them.
