Whatsapp calls are free as long as they are made over a WiFi network, or as long as we do not use up all the data volume that we have contracted with our phone operator. This data plan is already subject to a charge. If we were to use the contracted amount of GB, then we would have to pay for any additional data consumption.
If we can make calls and video calls through WhatsApp, it’s thanks to Voice over IP or VoIP technology, which uses Internet networks instead of telephone networks to put two people in contact with each other. This allows calls to be made anywhere in the world at zero cost, regardless of the distance between partners (provided, however, that the above criteria are met).
But all that glitters is not gold. In order to be able to make calls using the VoIP protocol, you need a stable connection (otherwise there may be failures). If you have good network coverage, you shouldn’t have any problems.
Remember that to be able to make calls on WhatsApp, you must open the application and select the contact you want to call. When you enter the conversation window, just click on the phone icon:
Button for calling
A message appears asking for confirmation to make the call. We click Call:
Confirmation of the phone call
We will see this on the screen while the call is being made:
On the other hand, if we are the ones who receive the call, we will see the following on the screen:
Each of these three buttons responds to a different function:
- If we slide the green button up, we can accept the call.
- If we slide the red button up, we can reject the call.
- If we slide the message button up, we can reject the call and reply with a message.
