Dear friends 
I have lost my Karbonn dual mobile on 26th sept. I have activated  mobile tracker , phone lock( asks password when switched on) and sim pins. I have deactivated sims so there is no problem of misuse. But i need data and  contacts 
Person who has found phone has switched on phone and changed 2 sims. As mobile tracker is activated now i got numbers of two inserted sims along with few codes MCC, MNC, LAC and CELL ID. 
I did not call  the numbers because afraid person may not  be willing to return the phone 
I have with bill ,box and IMEI numbers 
Please suggest me  how to get the phones 
Thanks in advance
