I am selling this phone because I am ill. There are no problems with the phone, I have been using it for a long time. You can take a photocopy of my NID card as security, and you can record a video of our conversation while taking the phone. If needed, you can take a written statement with my photo on a government stamp. You can even come to my house, sit and have a cup of tea, and take the phone with you. Gazipur, Deker Chala.
