This comes with I believe was everything that was originally included, other than the pay as you go top up.  But the envelope it came in is still present.

I charged this and it still turns on.  Although I can't say how long it holds a charge for.  I barely used this back in the day, I've never been a phone person.  It was carried only for emergencies, which there was none!

I got this for a birthday between 1996 and 1998, so its getting on a bit now!
