According to the program’s Terms and Conditions, it is open to selected models from Apple, Vivo, OPPO, and Samsung itself. In total, there are 97 devices that have been listed in the documents and the actual rebate that customers would receive also depends on the condition of their phone. As for the free gifts, pretty much all the Vivo and OPPO phones as well as Galaxy A, J, and C series that have been selected for this program would receive Galaxy Fit-e. On another hand, iPhone, Galaxy Note, and Galaxy S devices are eligible for Galaxy Buds instead. Alternatively, consumers can also obtain Galaxy Fit-e for free when they purchase any of the three Galaxy S10 devices outright. For further information, head on to iChanged’s official website.
