Hello everyone !!!

So, i'm back with my stupids questions about IMEI and ESN codes (sorry, i'm french, it's the reason) !!!

I will buy a lot of BB in US for repair or parts. But, how can i known if they have a sim slot ?
In fact, for exemple, an AT&T and a Verizon version have always ESN and not IMEI ? And T_Mobile have always IMEI with slot sim ?

This is by the way it's work at USA : one carrier have ESN or IMEI or could have the both ?

And at final, what it's mean "BAD ESN" like i read ?

Thanks a lot !
