Dealing with No Caller ID calls on your iPhone can be frustrating, as these calls often originate from telemarketers, scammers, or unknown sources. Fortunately, there are several effective strategies to minimize or block these calls, enhancing your privacy and peace of mind.

1. Utilize Built-in iPhone Features

Apple provides several built-in features to help manage and block unwanted calls:

4. Enter a dummy number like "000-000-0000".
