Interval rates

Interval rates There are different interval rates for calculating phone bills (such as 1-second, 6-second, 10-centime, 20-centime intervals), which makes simple representative comparisons practically difficult. Many telecom providers charge per second after a certain minimal length of time (usually 30 seconds). Therefore, you will end up paying for the exact amount of time you stay on the phone. This way of calculating fees is the most transparent to customers.

Other telecom providers charge fees in 6- or 30-second intervals. Partially fractured intervals will be added in full. For example, fees for a 31-second call would be:
- for 6-second intervals: 36 seconds
- for 30-second intervals: 60 seconds
Thus, short calls to expensive destinations result in higher costs.

Other telecom providers such as Swisscom calculate fees in 10-centime intervals. Depending on the destination of your call, you will receive a certain amount of seconds costing 10 centimes. As soon as this time is up, the next interval will begin. If you have a counter, you will be able to see this. Thus, short calls to local destinations will result in higher costs.
The table below illustrates these proportions. Minute rates according to advertisements were used for this comparison.
