Calling Apps

Meta-owned WhatsApp is reportedly developing a new feature, "silence unknown callers", which will allow users to mute calls from unknown numbers while still showing them in the calls list

IMEI is a unique, 15-digit number and is used to identify a device on a mobile network

The company is yet to reveal how many users will finally be able to join the group call. It will come to know when the new calling feature is rolled out globally

Such savings are possible if you use an app that lets you make calls using Voice over Internet Protocol (VoIP or IP telephony)
