Sim Card????

[Unregistered]

I found half of a nextel phone at the junkyard the other day, what I am wondering, is there a way to use the sim thats in it and get the information changed without knowing the passcode to it?

I think it's not possible.
Why don't you buy a blank sim card? You can do whatever you want with it.

I thought SIM cards were only GSM. Isn't Nextel iDen? Does iDEN have SIM cards?
