WhatsApp uses VoIP (Voice over Internet Protocol)

WhatsApp calls will typically disconnect when you receive a regular phone call.

Some carriers may force an internet disconnection while a regular call is active, which can lead to WhatsApp dropping the call.

Hello!

Reset your Network Settings (Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings,) then perform a Forced Restart: Force restart iPhone - Apple Support

Reach out to your carrier if the problem persists.

Have a great day!
