I haven't put a live sim in but it was fully functional when replaced otherwise I wouldn't have kept it as a backup. Comes with what you see, which I believe is everything that came with it, including mains and car chargers, data cable and earphones, as I don't throw stuff away! I didn't even have to charge it, so the battery must be a goodie. I can't remember the last time the phone was used, but it's a number of years ago. I have deleted everything as far as I can tell. Securely and promptly despatched by Royal Mail.
