How/where do I insert a sim card in the iphone 5

http://support.apple.com/kb/HT5163

On th iPhone 5 the is a tiny hole on the mid right side of the phone, with the sim eject tool included or a paper clip push it in as far as it will go and the tray should pop out, put the sim and push tray back in.

Hope this helps :)

Thanks, it helped.
