What will happen, if two phones with same IMEI and run on same network?
 

Who knows answer?
A. Both phones work fine!
B. Both phones do not work (no signal, no network)!
C. First running phone is works, second one does not work (no signal, no network)
D. Both of phones sometime lose signal (no network).

I test it on two T10 in the same network & same room :D . We can speak with one fone with the other fine.

Nothing happens,

the provider is just checking if the mobile equipment is stolen (put on black list) or not. if it's ok you can use it.

The network shouldn't accept the 2nd phone with same IMEI,, but is easier to pass this check.
Most providers don't care about this things,, and most providers don't use Black, Grey list.
