Sunrise prepaid doesn’t need to be cancelled because there’s no base monthly fee for you to pay. If no mobile data has been used, no calls have been made and no SMS have been sent in the last 17 months, Sunrise will automatically cancel your prepaid number. The remaining credit will be lost and the phone number will be returned to Sunrise without any compensation. We’ll send you several e-mails before we cancel your prepaid number.

To allow us to send you the new SIM, you need to top up your prepaid balance by a minimum of CHF 20.– in the next 48 hours, regardless of your current calling time credit. The replacement SIM is free and all of the top-up amount will be credited to your prepaid balance. You will of course keep your existing prepaid number. A replacement SIM can also be activated in a Sunrise shop. An official ID card is required.
The prepaid credit balance will expire if:
• The number hasn’t been used for 17 months. Examples of usage include topping up the credit balance, making calls, using mobile data or sending SMS. In addition, after the 17 months, the phone number will be cleared to be reassigned.
• The phone number is ported to another provider.
• The prepaid services are used in a way that breaches the contract.
Before the credit is lost or the phone number deactivated, you’ll receive reminders by e-mail. You should therefore make sure that the e-mail address you’ve provided in My Sunrise is up-to-date.
