6/128 phone, it is very good. I have used it for 3 long years, and so far there has been no lag or hang; it runs very smoothly. There are no problems at all, only the touch screen is cracked. Battery backup is Alhamdulillah very good. There is no charger or box with the mobile. Price is negotiable. As documents, a shop voucher or a photocopy of the NID card can be provided. Thank you.
