If you are not receiving any calls or SMS from one particular number, it might be the case that this number was blocked by mistake. You can unblock it by following these steps.

On the other hand, if you are not receiving calls or SMS from any number, you may want to try switching your mobile off and on again. If this does not work, get in touch with us by sending a message on WhatsApp, Facebook Messenger, or Live Chat so that we can help you.
