Will swapping SIM swap tel # ?

[Chopstix9]

So I have my old Nexus as a spare for the wife now as I bit the bullet and paid full retail for an S5. If I take the sim out of her phone and put it in my old one, would that make the phone active on her line? Obviously I would assume at the least I would need to do a clean flash with her sim in the phone? Would that work?

Are you serious? Phone number IS CONTAINED in the SIM card. Why on earth should it be phone-bound?

Yeah the phone number is bound to the Sim card not the phone. However sometimes you can have you old number on a new Sim card. This will render your old Sim useless and not every provider has this option..

I figured as much but just wanted to be sure in case the wife's phone goes boobs up and I need to swap it out with my old one.
