Anybody know if it’s possible to obtain multiple cellphone SIM cards that are all activated as the same number?

I noticed when I upgraded viv’s phone a ways back that it came with a new SIM, which I did not use. If I had, would the old SIM remain usable? If not, is the deactivation automatic?

There are two parts to this question, then. Is it technically possible to have a dual SIM number, and if so, how does one go about obtaining a second, duplicate SIM without alerting the cell phone police that you are threatening their holy monopolistic bizmodel?
