Rubrica4146 can be used whenever you need to add a prefix before a telephone number without changing your address book.

It's the best way to manage your SIM card with dual billing profile (personal/business). Moreover, it allows you to make anonymous calls by hiding (blocking) your caller ID. It works only with the following countries and codes
- Hong Kong: 133
- Ireland: 141
- Japan: 184
