Why can't make out calls on my phone

[Swamy S Nayak]

I can't make any outgoing calls on my oppoA37f. I can receive calls just fine. I still have 4g network and can still send and receive text messages fine and surf the web. But can't getting any outgoing calls.

Welcome to Android Central! What happens when you try to make the call? Do you get an error message, or does it just hang there? Have you asked your carrier about this? They might want to replace the SIM card.
