If there is insufficient credit available at the time of automatic renewal, package renewal will be temporarily suspended and usage will be billed at the basic tariff. As soon as sufficient credit is available, automatic renewal will be re-activated and the package price will be deducted from the credit.

Services that are not included (e. g. calls to not included numbers) will be charged at the basic tariff (e.g. calls at 29 centimes/min.). If the high-speed data allowance (500 MB) is used up before expiry of the 30-day period, unlimited further surfing is possible with a reduced speed of 128 kbit/s or an additional high-speed data package can be purchased.

During the bundled package’s validity period (30 days), the first change to an inclusive number is free of charge. Each subsequent change costs CHF 2.– and will be subtracted from your credit.
