@prion1, I do have a Koko Voice Sim, the options is CHF 5.00 for 365 days. It can be enabled in the customer zone, description as follows:

"Extend the SIM validity period by one year if the card is no longer used. Your SIM card will not expire, even if it is no longer used, as long as this option remains activated. Costs are charged annually in advance and reduced from the currently available balance, regardless of the current status of the SIM card.
