This is based on the W1 but may work with other phones.
The setting to export to sim was missing on my W1, I had thought it was a design problem but I found out the following by pure accident while moving my contacts from gmail to my live account.
Import or create your contacts into your live / hotmail account.
Edit them if need be and save them as csv file from inside live / hotmail. ( this is not required, its just handy to have a backup )
On the wp8 set the contacts to filter from hotmail.
Wait a few minutes.
Any new contacts will show up under phone or people
There should now be the option to export to sim :-)
Dont ask me how this works, I stumbled on it by chance :-)
