I want to clear a few things up.

The first phone i got was a Nokia 3330 (I dont use this phone now, of course!).

The sim card is so old, the company has taken my number away. does this matter?

And the on/off button has fallen off, but i managed to wedge it under the front and back cover, and it still turns on. Does this matter?

Any stories or experiencs are wlcome, because i dont want to make a fool out of myself hen i get to the shop.
