To attract more customers, OnePlus has offered to trade in your new smartphone for a reduction in cost towards the purchase of an OnePlus 2 or OnePlus X. The company is also offering free insurance if the trade-in amount exceeds Rs. 5,000. However, as reasonably expected, the trade in value differs from device to device, and is also affected by the age and condition of the device. The offer is valid till 31st December 2015 in select Indian cities.
