Will text messages intercepted by high-frequency harassing calls block my local number?

No.

SMS messages intercepted by high-frequency spam calls will not deactivate your local number. High-frequency spam call blocking is a feature on your phone that helps you automatically block text messages from spam calls. It will not affect the normal use of your mobile phone number, nor will it deactivate your local number.

If your mobile phone number is reported as a spam call, you may receive a text message from your carrier informing you that your mobile phone number has been deactivated. In this case, you need to contact your operator to resolve the issue.
