I am sick so I am selling the phone in my hand, no problems, using it for a long time. As security, you can take a photocopy of my NID card, you can record a video of me talking on the phone, if necessary, you can take my written statement with a photo from the government. Even if you want, you can come to my house, sit at home, drink a cup of tea, and take the phone away.
