    I'm aware the Verizon iPhone 5's are factory unlocked out of the box in which they will work on GSM networks (AT&T and T-Mobile) if you have a nano sim or file your sim down to a nano size.

    What I'm looking to do is buy a used iPhone 5 for my cousin who happens to be on T-Mobile. She'll transfer her sim to a non sim. However since iPhone 5's are still expensive, I would like to know if the following cheaper approach will work.

    If I buy a Bad ESN iphone 5 from Verizon, will it still be unlocked to work on GSM networks? I'm not looking to jailbreak it or do the Gervy sim unlocked or anything of that sort. I just want to use the factory unlocked and would love to go down the cheaper route of a BAD ESN Verizon iPhone 5.

    And yes, I'm aware T-Mobile is coming out with the iPhone soon but it won't be discounted. And I appologize if this question has been asked, I was unable to find a thread that answered my specific question

    I can see that working depending on why it's ESN is bad.

    There is a national blacklist coming and that would keep it from working

    as of now, a bad ESN CDMA iphone 5 can be used successfully on a GSM network since there is still no IMEI blacklisting in the US. but then again, i would only do this depending on why the ESN was bad. if the phone was stolen, thats one thing, if not, then maybe i would.
