If your iPhone is not receiving calls, the problem could be due to multiple reasons, ranging from poor network connectivity and change in call settings to the SIM card becoming faulty or damaged.
Luckily, in most cases, the problem of iPhone not receiving calls ends up being due to poor network connectivity, iPhone automatically switching to Driving Focus Mode and other settings related issues.

1. Go to Settings > Phone > select the Call Forwarding option, located under the “Calls” section.
2. On the Call Forwarding screen, make sure Call Forwarding is set to OFF position.

Sometimes, the problem is due to an iOS or Carrier update waiting to be installed on your device.
1. Go to Settings > General > About.
2. On the next screen, tap on Install (if an Update is available).
7. Check Blocked Numbers
If you are not receiving Calls from a particular Phone Number, the problem could be due to this Number being accidentally blocked on your device.

Once the Number is unblocked, you should have no problem receiving and making calls to this Phone Number.
8. Turn OFF Silence Unknown Callers
If Silence Unknown Callers feature is enabled on iPhone, you won’t be receiving Calls from those who are not on your Contact List.
1. Go to Settings > Phone.
2. On the next screen, disable Silence Unknown Callers option.
9. Remove and Reinsert SIM Card
If above methods did not work, the problem could be due to faulty, damaged or improperly inserted SIM Card.
To confirm, remove SIM Card from your iPhone and inspect the SIM Card for visible signs of damage. If you do not find any signs of damage, reinsert SIM Card into your iPhone and see if you can receive Calls.
If you have another iPhone, insert the SIM Card into another iPhone and see if it is working. If the SIM Card is not working on another device, it confirms that it is damaged and needs to be replaced.
