Welcome to Vodafone Community
Turned permissions on and off, VPN on and off, reinstalled, refreshed app installs and APNs... still can't make or receive a whatsapp call using mobile data. I can use all of the other features including sending and receiving media. Read stuff about User Datagram Protocol settings and port forwarding but no idea where to check those.
Anyone got any ideas?
Seems to be ok on my phone via Mobile Data but I do find a slight delay on an actual voice call.
Current Phone > Samsung Note 20 Ultra 5G - SM9860 Snapdragon.
Samsung One Ui 3.1 / Android 11.
Exactly the same thing is happening to me when I am using mobile data I also can't able to receive WhatsApp calls but I got solved my issue with clearing the app caches in apps setting and I think should also try this and I hope it will works for you too and if this doesn't work then you can also try this WhatsApp Plus to ensure that if you are encountering the same issue on this app then email to WhatsApp.
