OnePlus Assured Upgrade will cost an additional Rs 199 and will be available only for OnePlus 6T purchases done between tomorrow i.e. January 19th and January 27th. The buyback sum itself is determined simply based on how old your phone is. For usage of between 3-5 months, you get 70% of the original value, 55% if it’s been more than six months since you bought it and 40% for 9-12 months. The offer is incompatible with purchases that are over a year old or for existing OnePlus 6T owners. Commenting further on the launch, Vikas Agarwal, General Manager, OnePlus India, said, “At OnePlus, our constant endeavor is to innovate and delight our loyal community of users. Our community has always been technologically forward and a vast majority of them also upgrade to subsequent OnePlus devices. With the ‘OnePlus Assured Upgrade’ program, we are excited to make upgrading to future OnePlus flagships even easier.”
