Azercell extends the period during which you can make free calls from Azerbaijan in this direction until March 6 inclusive in order to ensure uninterrupted communication with our citizens currently in Ukraine, as well as with relatives of our citizens living in this country. This opportunity is available to all Azercell subscribers. In order to avoid the risks associated with possible congestion on mobile communication lines in the direction of Ukraine and to prevent cases of abuse of free communication, the mobile operator asks its subscribers to use preferential terms when making calls for no more than 3 minutes.
