There is not the slightest problem with the phone. It is in absolute fresh condition. I bought it for my older brother 3.5 years ago and he took it with him to Australia. But the SIM card did not work there. Only Bangladeshi SIMs work. So it was in a completely fresh, unused condition. Now he has brought it back when coming to Bangladesh.
The price is completely fixed. No bargaining.
You need to come to Uttara-10 Kalyan Samiti Office.
