When I trade my iPhone for a new one with Verizon [View all]

And let’s say I have them send it to my house, is the cellular service of that new phone already activated when I get it and already has a new Sim card in it so all I have to do is the quick start to transfer the old phone information to the new phone?

Same would apply for instance if I bought it through Costco and didn’t get it at the store does it come activated to the company I have cell service rep in this case Verizon?


Does the same apply to T-Mobile or AT&T if you know?

CLARIFICATION

Not talking about transferring info from one phone to the other, talking about the phone being ACTIVATED to the cell carrier, is that done before it is shipped?
