My experience was a little different.

I got a sealed Orange prepaid kit with CHF 20/- in credit through Ebay in mid November.

I reached customer customer service by email and phone but they told me the serial number was not found in the system and hence could not assist me.

On my own initiative after about 7 days, I went to an Orange outlet ( near Zurich HB ), presented my ID to a sales rep, and selected a number out of 4 that was presented on the screen. My SIM got activated within 6 hours - received two SMSs which allowed out to use online resources.
