--> https://www.yallo.ch/kp/dyn/web/pub/...?cont=contact1

--> 0900 123 999

they have a website www.yallo.ch there are lots of contact details and information there.

Your puk code is on the little package/box that your sim card came in, its where you had to scratch of to use card in the first place.
