Assalamu Alaikum
This mobile was sent from abroad by brother-in-law for my sister.
My sister used it for one year, there is no problem. Single-handed used phone, no servicing history. You can check and run it for as long as you want. You can take NID card as security. Moreover, no box or memo came from outside. You must come to the location to take the mobile.
