Dear @Commentor423
As the user Gaeilgeoir wrote previously, Swisscom offers many different payment methods and we keep checking continuously which new payment methods we want to offer to our customers.
We have been offering TWINT as a recurring payment method since this year.
I assume when you write 'Autopay' you don't mean the service 'Autopay' you refer rather an automatic payment method – eBill offers the option of automatic debiting from the account, you only have to store this once in your eBill settings.
If you have further questions regarding the payment possibilities, I recommend also to contact our customer support directly, so that we can assist further.
I hope this make sense and wish you a pleasant Advent Season.
