You will get a new sim card (and new mobile #) on any of these networks:
Aircel or Vodafone India.
You will then give us the mobile# and keep the phone on for 24 hours. We will have some messages sent to the phone and you will need to tell us what they are (mainly sms codes we use to sign up to indian websites).
We will also send recharge credit to the phone number after this testing. You will need to confirm/prove to us the credit was successfully added to the balance of the mobile#.
