How to intercept harassing text messages by old computers

If you want to block harassing messages, you can try the following methods:

1. Open the "Settings" menu of the old machine and find "Call Settings" or similar options in the menu.

2. Find "Anti-jamming" or similar option in "Call Settings" and enter it.

3. Find "Blacklist" or similar option in "Anti-harassment" and enter this option.

4. Select "Add" in "Blacklist", then enter the strange number to be blocked and save the settings.

Please note that different brands of aging machines may operate in different ways, so the above steps may be different. In addition, the old machine may not have advanced interception function, so you may need to consider using other devices or software to intercept harassing text messages.
