Once you have done that, depending on the amount of credit you have in your account, you can start creating your “alias” numbers. A payment of the minimum, $1.99, will get you enough credit to create one, temporary telephone number. You need to re-direct calls or sms from the fake number(s) to your cell phone number. You can then use the temporary number(s) for whatever it is you wish to do. Once done, you can “burn” (destroy) the number. All that your contacts or friends will get to hear when they re-dial the temporary number at a later stage is a recorded voice that probably says, “This telephone number does not exist”.
