My iPhone 7 is unable to make calls or receive calls but at time if I received calls I cannot hear them
what could be the issue & how can I disabled the call restrictions ?

If you experience poor sound quality in certain areas or locations, it may be due to a weak signal on your device. Check that your carrier provides consistent mobile network coverage in your area. A broken SIM card may affect call quality. Check your SIM card for any damage, and make sure that it is properly installed.
