A virtual number is a number that is in the cloud, it has no connection with a physical line and must be diverted to an IP line, virtual pbx or to other fixed or mobile numbers to receive calls.
These numbers are as usual, with national geographic coding (for example, 951 xx xx xx or 810 xx xx xx). That is, 9-digit numbers with different prefix depending on the province chosen, or international numbers (for example France + 33170XXXXXX, + 44232XXXXXXX).
You can keep your current phone number by carrying it to Universal Telecom or request a new number.
