(Automatic) Anonymous Calling & Prefixes for Android

Decide who sees your number without typing codes yourself every time. With PaSS, you automate the use of prefixes (like *67 for anonymous calling or *82 to show your number). You set up a smart rule once, and the app does the rest based on your contacts, your calendar, or your call history.

Get the most out of (automatic) anonymous calling with these handy options:

Decide who you call anonymously and who you don't

Do you prefer to call anonymously by default? First, turn off your caller ID in your phone's settings. Then create a rule that automatically adds the code *82 in front of the number when you call someone from your own contacts or a special group. The other way around is also possible: call with caller ID by default, but let PaSS add the code *67 when you call unknown numbers or business contacts.

Smart call back with caller ID

When you return a missed call, the other person already has your number anyway. Is your phone set to anonymous by default? Use the 'Incoming History' condition. PaSS will automatically place the right code in front of the number when calling back, so the other person instantly sees it's you.

Build your own smart tricks

Because you can combine multiple actions in PaSS, you can come up with handy tricks. For example, create a rule that looks for '###' in the number you type. Then set two actions: let the app delete these hashes (replace with nothing) AND have it put the code *67 right at the front of the number. Because this lets you simply type those hashes quickly after a number, you can decide super fast per call whether you call anonymously.

Privacy during and after work hours

Set a rule so you always call anonymously during office hours, but with caller ID on the weekend. Because you can link rules to fixed days and times in PaSS, you never have to adjust your settings manually again after your workday.

Worldwide and handy for country codes

The codes for anonymous calling aren't the same in every country. Because you type the codes yourself in PaSS, it always works. In addition, you can use these types of rules perfectly to automatically put the right country code (like +44 for the UK) in front of your saved contacts when you're abroad.
