I have Verizon as Carrier.

With my iPhone, sometimes I want to call my mother in Italy, on her Whatsapp account. So I open the Whatsapp app, go to the last chat thread with my mother and tap the top-right icon with the phone.

Sometimes, though, the call is performed using my U.S. Verizon number rather than my WhatsApp account and therefore Verizon has already charged me a few times for international calls!!

How can I make sure to perform the call using Whatsapp rather than the normal phone?

Thank you very much

So turn off mobile data for WhatsApp in the phone settings.

That will force WhatsApp to only use Wifi for its connection.

I turned on mobile data as I was away from Wifi recently, but normally I only allow Wifi for WhatsApp.

  • I am afraid I cannot do that. I need to use Whatsapp also when I am not under Wifi coverage... Commented Aug 22, 2022 at 7:42
  • If I read the question correctly the problem isnt that WhatsApp is using mobile data, instead WhatsApp somehow falls back to a normal phone call instead of a WhatsApp call over data.
