The networks fraud prevention works in such a way that having two devices on at the same time with the same esn WILL trigger a flag. They will investigate the matter, its just a matter of when. This is how they prevent you from being cloned by a criminal looking to use your long distance. It's not about taking rights from you but protecting the rights you have which are more important.

I only listed the method of changing a ESN, but to make this work there are several things which must be cloned, and they will vary based on carrier as well. In general if you don't have enough reason to do this to search down the info you need you really shouldn't mess with this. It can and will get you in trouble if you make a mistake and leave 2 devices on with the same esn.

If you really did want to do this, you need to clone esn, msid/mdn, vision user name, password, hdr pass (dmu). And then destroy the original device. Typically it would be best to buy broken phones to take a ESN from as they are already near worthless.
