Samsung Galaxy S7 edge G935F Sold as spares or repairs, no returns The phone turns on it says sim not registered on network. The phones screen is damaged at times it comes on at other times it doesn't work. The condition of the phone is poor, the front & back is smashed, other than this does show signs of use with marks and scratches. You are buying only the phone and nothing else, the phone has been checked to the best of my ability but still could have other faults.
