ATTENTION: Not all providers and not all country support the prefix #31# to make an anonymous call, try it first to use. Some operator uses CLIR, Caller Line Identification Restriction so you must call your operator provider for activation hide caller ID.

Below you can find a not exhaustive list where it works. Thanks.

Sometimes, due to privacy issues, we may need to make calls without showing their phone number from those on the other side, the application allows you to make an anonymous call quickly and easily. The app put before the prefix #31# to the numbers dialled with the dialer, to the numbers in the phone book, so who will receive your call will not see your number, but the words "Unknown" or "Reserved number" or "Private number". The application is not memory resident, it will not consume the battery of your mobile phone, but on the other hand, to be able to call as anonymous you have to necessarily use the application.
