...I highly suggest you stay away from this. You are going to get yourself caught, and fast. But if you have a lot of money to blow, you need to get yourself a prepaid phone with a sim card, no contracts. Because after you go and do something you will need to separate the two immediately and make sure they are never found.
Anything you can do on a phone, you can do easier and safer with a computer. With less likely chances of 1 getting caught, and 2 you can practice legally...
