Program INTERFON intercepts calls (i.e. calls automatically goe through TravelTele.com network) only when:
Number is dialed in the “+country_code_area_code_phone_number” format*
Number is dialed in the “00country_code_area_code_phone_number” format*
Number is dialed in the “011 country _code_area_code_phone_number” format
* Except the cases when first two digits of the destination number match the first two digits of your SIM number – these calls will be considered “local” (inside of the mobile provider network and a host country) and will not be intercepted.
To make a local call, it is enough to dial the number in a local format, without the country and area codes. Numbers that are less than 8 digits will not be intercepted. To make a local call, go to the INTERFON main Menu and select “Make Call”.
