Your information is incorrect Standard girl, there is a code it's 6 digit's and alphanumeric, and it does come via SMS from Swisscom (although you can use the email link), as I still have it in my messages. You must enter the code to access website to begin the unlocking process. Once this has taken place they send you and email, follow the steps, sync' with itunes and your done.
"Dear Mr xxxx
Thank you for your enquiry.
Swisscom has asked Apple to deactivate the SIM lock on your iPhone. The SIM lock must now be removed after 24 hours by synchronising with iTunes. SIM unlocking instructions can be found at this link:

You don't have to wait until you receive an SMS from Swisscom, this email is a replacement. After 24 hours you can follow the instruction under point 4 "synchronising".
If you have further questions we would be happy to answer them by e-mail, or give us a call on our toll-free Hotline on 0800 615 615.
We are available from Monday to Friday from 8:30 till 18:30 as well as Saturdays from 8:30 till 17:00.
Kind regards
Your Swisscom Team"
