As promised, Realme has added VoWiFi calling feature to Realme X via February 2020 update. Jio and Airtel SIM card users in India can make Wi-Fi calling on their Realme X now onwards. The main advantage of VoWiFi is that your call won’t be disconnected anymore due to the network coverage issue.

To enable VoWiFi calling on your Realme X for Jio and Airtel SIM, install the February 2020 security update version A.12. So, first, check for the update RMX1901EX_11_A.12 by going to the System update menu and then follow the below steps to enable VoWiFi on Realme X.

  • Install software update version A.12 on Realme X
  • Connect the phone to a Wi-Fi network
  • Go to Settings > tap on SIM Card & Mobile Data > tap on Jio or Airtel SIM (SIM 1/SIM 2)
  • Tap on Wi-Fi calling > and turn on the toggle.

Now onwards, your phone will route all your calls via the WiFi network or your Jio/Airtel network, depending on which signal is strong.

FYI, the RMX1901EX_11_A.12 update isn’t the Realme UI (Android 10) update for Realme X. It is the ColorOS 6.0 update, but it is also the pre-requisite update for Realme UI. All users are recommending updating their Realme X to this version.

Along with the February security patch, the RMX1901EX_11_A.12 update installs some third-party apps to latest version. Also, it fixes some known bugs, and improved system stability.
