Storage on SIM Card

[oaooao]

Is it possible to store all the customiation on a SIM card and have it work from there?
e.g. contacts, ringtones, etc.

If so, how?

Thanx.

According to this -
"You can save contacts from a SIM card to a Windows Phone, but you can't save contacts from a Windows Phone to a SIM card"

Contacts are saved to your microsoftaccount on line.

Ringtones, Pics, etc have to be saved to SD Card not to sim card.
