Why can't i receive calls

[Android Central Question]

I have a galaxy s9 and I don't receive any calls or hear my phone rings
Dose the phone supposed to be set on LTE/CDMA in over for me to get calls

Do you have a SIM in the phone, activated and with credit? https://forums.androidcentral.com/showthread.php?t=409154

Welcome to Android Central! Can you make calls? Have you contacted your carrier about this?
