Depending on carrier/retailer, you may be required to return your damaged or defective device using the pre-paid shipping label provided with the replacement device. You will need to return the damaged or defective device within 10-15 days to avoid non-return charges. If the device was lost or stolen, the requirement to return the device does not apply. However, if the lost device is found, you should return it by using the pre-addressed, pre-paid return label included with the replacement device.
