ERROR " NO SIM CARD"

I Purchased dell streak 5 from ebay and when i insert SIM it says No SIM card. The sim works fine with other phones and tried different operator SIM cards.

I am in india and using vodafone .

How do i claim my warrenty? when i called dell mobility support they say can't assist you to replace the phone in india and can be done in US only.

Is there something i can do to get the support in india?

I have applied for transfer of ownership of the phone to india and never heard from you guys.
