The other day I had to reset my password on to my providers website. To reset my password I had to provide the last six digits of my sim card. I was at work so had no way of popping the sim out etc, plus with it being a micro sim i was unsure whether the number would be on there which meant relying on the packaging which came with the phone.
Luckily there is an easier way and you can get it from the phone. If you go to
Settings -> General -> About
Then scroll down and you will see ICCID. This is your sim card number, hope this helps.
