Activating your CoreESIM for Russia is a straightforward digital process. Following your purchase, CoreESIM will promptly send a QR code to your email address. You should scan this code within your phone's cellular or mobile data settings to provision the eSIM profile. For convenience, consider performing this step just before your journey or using the free Wi-Fi available at major Russian airports, such as Sheremetyevo (SVO) in Moscow or Pulkovo (LED) in St. Petersburg.
