The seller of the phone should be able to get some sort of confirmation off of his own account showing he is not currently making payments on it. If the employees are only saying to see if the SIM works, they are just being lazy or ignorant! With the owners permission they can look it up, or call support from the phone and have him ask them to verify on speaker so you can hear. I'm just trying to say there's other ways to get the info before buying.
I'd say that if you've bought that many you are pretty lucky. But for the blacklisted one that worked on other carriers...expect it not to on AT&T very soon and all other US carriers around the end of the year. Right now T-Mobile and AT&T share their lists, but don't use the same one, so it'll often take a few weeks to catch up. As I understand it, once the national list is in place, all carriers will be using the same one so it'll be more instant.
I have spoken to a few people who bought their phone used and all seemed good, but then nearly 2 months later it got blacklisted! Some people are apparently selling it, but then waiting a month or two to report it stolen!
I just hope that if one of your customers gets blacklisted a few weeks after buying from you, you will be willing to at least exchange it.
But before you try and sell this one, please consider that it's practically a given that it's not gonna work for very long.
Also, (and I'm not sure of the ramifications here) keep in mind that you are knowingly in possession of stolen property. That by itself is probably not a big deal for you, legally speaking, since it happens to so many people and hardly no one knows what they are buying when this happens to them. But if you sell it, you will be knowingly selling stolen goods. If one of your customers gets blacklisted, you could be the one held liable.
Don't take it wrong, I'm just trying to help!
And I'm just curious, what do you mean by "carrier flashing"?
