  • Airtel Wi-Fi calling claims to enhance indoor voice calling experience for smartphone customers.

What is Wi-Fi Calling?

  • Wi-Fi Calling is aimed especially for areas where cellular networks are not strong.
  • It uses high speed Internet connection, available via broadband, to make and receive high definition (HD) voice calls.
  • Users don’t have to pay extra for these calls as it is using a Wi-Fi network.

Features

  • This is similar to a voice call using WhatsApp or any other over-the-top messaging platform, but the difference is that call is from one number to another, and not using an app.
  • Since these calls use stable Wi-Fi connections, call drops are not expected to be a problem.
  • It can be configured on compatible smartphones by upgrading operating systems to the version that supports Wi-Fi Calling, and enabling this in Settings.
  • Keeping VoLTE switched on will help in seamless voice calling, but this is not essential.
