SO SIM Card - few question | Technical service details | Consumer forum

Hi:

I'm new to this and looking to get a SIM card for an iphone. Trying to get a better understanding on how this works. When people sell their sim card (as in this forum), It's not just the sim card, but the fact that the sim has a valid speakout account (activated) or that the seller has the appropriate activation receipt so that the sim can be activated - is that correct?

Is there any way that you could buy a SO sim card and SO would refuse to allow it to be used (other than physically damaged).

And as far as account details go, what account details of yours (personal information) does SO keep. I.E. could someone call them up later and claim that they lost their sim card providing proof of the account details on their system and then hi-jack the card and credit back?

Thanks,
Jaime
