[Surender_123]

I have lost my Samsung phone and the sim.But i do not have the imei number to track the phone.
I was using a tata docomo sim and have all the contacts in that sim.
Hence could anyone let me know about the procedure to get back the contacts which is there in the sim.

If your contacts were synced with google account, then they will automatically stored into your new device after log in to your google account....
