You can find the payment slip details for paying your bill in my yallo under "Bills and Usage". You can view your recent bills there at any time and download them as PDF files. You can also see there whether you currently have the paper billing option activated. To learn how to change to email billing, see: "Receiving bills by email"

We recommend paying your bills by online banking – it's quick and convenient. If you still want to receive a copy of your bill with a payment slip, you can order it with the following form: Please note that there is a charge for this service (fee per order: CHF 10.00).
