In order to use an Infocaller virtual number, you need to be granted permission by the Infocaller account administrator.
When the administrator adds you as a user and has defined the virtual phone numbers that you can access, you will have to log in to Infocaller App using the email authorized by the administrator.
From that moment on, you will be able to make calls from Infocaller App using the virtual numbers authorized. However, in order to be able to use the phone number to make calls using the account’s credit, an additional authorization from the administrator is required.
If the administrator removes your permissions, a new registration will be required to use the App and you will not be able to access the credit of the Infocaller account.
