Why does my iphone can’t recieve a call or make a call? Whenever I try to dial, my phone goes offline. I have already tried resetting my network setting, updating my software , changing my prepaid sim and etc. but still not working. Also, everytime I open the call forwarding or call waiting , my network also goes off and I can’t see enable button, I can only see it loading.
Check your iPhone settings
Go to Settings and turn on Airplane Mode, wait five seconds, then turn it off. Check Do Not Disturb. Go to Settings > Focus > Do Not Disturb and make sure it's turned off. Check for any blocked phone numbers.
