That's why I ship my phone without sim.
I activate the phone in my house place a test call with the right sim in phone.
Reset the iPhone.
Ship.
Keep the sim or destroy it. It's pretty much useless at this time when you aol the line to someone else.
I have a new udp sim in my old 5. Works fine. To me after you have a live sim you can do whatever you want to do with it.
After you activate the phone and make a test call, do you remove the SIM before or after you reset the phone. Does it matter?
By reset do you mean, "erase all content and settings"?
Once you have done this, you AOL the line, and destroy the SIM correct?
