sim cards

hi everyone, before i have to go to the cingular store, is it possible to have more than one sim card? i currently have a razr v3, and i just purchased a l6 off of ebay. rather than switch sims every time i want to change phones,can you have more than one sim so i can keep a sim in each phone. thank you all for the help. jim

I'm pretty sure you can only have one activated sim card on a account. Would be nice though.

I've heard of a way to use 2 sim cards on 1 account because my friend said he did it...but I'm not going to go there because it's illegal. Why not buy a prepaid sim card for the other phone?
