[Q] imei numbers for Mate7-T10 Gold. topic

Hi All,
last week I got a AM7-T10 Gold 2/32GB from China local market.
It supports 2 sims and both is active at the same time , I can call from one sim to other.
My problem is; I can not get the second imei number, when I key in *#06# it always shows me only one imei (always same one) wheather I switch to sim1 or sim2 or both. And there is only showing the same imei at the about the phone screen.
Can anybody help me ?
