Gaeilgeoir @Livingen45 Please take a look here: https://www.swisscom.ch/en/residential/help/mobile/pin-und-puk-karte-entsperren.html You can find the PUK in MySwisscom, click on the link "Go to my Swisscom"
Gaeilgeoir Under the position "Mobile" -> "SIM & Devices". You can see that for the German version here: https://community.swisscom.ch/t5/Archiv-Telefonie/Wie-finde-ich-den-Puk-code/m-p/493867$ or try this: https://www.swisscom.ch/myswisscom/d?useCase=viewPuk And if you still don't find it, please call the Hotline 0800 800 800. It doesn't make any sense to place the same request for several times here.
