Here are some tips to help you stop spam calls:

1. Register your phone number with the National Do Not Call Registry.
2. Use call blocking software or apps that can automatically detect and block spam calls.
3. Do not answer calls from unfamiliar or suspicious numbers, and do not return calls to unknown numbers.
4. Avoid sharing your phone number online or with businesses unless it is necessary.
5. Be cautious of sharing personal information with callers, especially those claiming to be from companies or government agencies.
6. Use your phone’s built-in call blocking feature to block specific phone numbers or area codes.
7. Be cautious of voicemails or text messages from unknown numbers and do not click on any links or download attachments.
8. Consider using a virtual phone number or disposable phone number when signing up for online services or making purchases to avoid giving out your personal phone number.
9. If you continue to receive spam calls, report them to the Federal Trade Commission or your phone carrier.
