Infocaller App allows you to use several phone numbers and change between them whenever you need it. For security purposes, every time that a phone number is changed, we send a SMS with a verification code to that number.
If you want to add a new phone number, you have to:
Press on ‘Change mobile number’
Enter the new number.
Verify the phone number with the authentication code sent through SMS to the entered number.
