      Frequently asked questions (FAQ)

      During a voice call in a 4G network without VoLTE, the smartphone temporarily switches to a 2G/3G network and switches back after the call is ended. The VoLTE technology allows making calls and staying in a 4G network.

      The service will become available automatically under the following conditions:

      • The smartphone is included in the list of supported devices on the website. You will also receive an SMS notification;
      • You should stay in the LTE network zone;
      • SIM card supports the LTE mode;
      • You should activate VoLTE in the smartphone settings.

      If the smartphone was connected to the LTE network before and during the call and the network icon did not change to 2G or 3G, the VoLTE technology was used for the call.

      During the calls, the package of minutes will be spent according to your tariff plan. Internet traffic is not spent.

      All calls made via VoLTE will be paid as usually, according to your tariff plan.

      VoLTE is available throughout the entire territory of Kazakhstan where the LTE network is supported.
