Why Does My Call Fail after 4 hours iPhone?
Every time a call fails on the iPhone, it indicates that your device has lost connection to the tower of your network operator. Also, it can be possible that your network operator has set the call limit of 4 hours. There may be multiple reasons why this must be happening. One reason can be your iPhone may be too low for keeping the communication going.
Also, the radio may be overheating after being operated for such a long time & unable to function within the specifications. Another possible reason may be that your network provider has some feature that shows an error message whenever a call goes on for such a long time. These are only a few of the possible causes why a call may fail after 4 hours on the iPhone.
