Oppo A17 4/128 has been used by my mother for a long time. No repair work has been done. I am selling it because I need urgent money. Battery backup is very good. The phone was taken from a friend of mine who has gone abroad, so there is no phone box. I can provide an NID copy as security if needed. Price is fixed at 5.5 thousand. Location: Dhaka, you need to come in front of the Women and Children Hospital in Ashulia.
