WhatsApp calls do not work in Japan?
Hi, I have iOS 15.3.1 and I have been using WhatsApp calls successfully in Finland latest a few days ago. Yesterday I arrived Japan. WhatsApp messages are working perfectly, but calls don't. When I call, it rings to other phone. When other iPhone answers, it shows me just 'calling to....' and receiving iPhone shows 'connecting....'. Tha's all. We have also Signal app in our iPhones and Signal call are working perfectly. I have tried all possible settings and we are using wifi.
We have iPhone 11pro and iPhone 13pro.
Can any one help?
