The Business Flatrate is designed for standard connection use by business customers. If usage deviates considerably from standard use or if there are reasonable indications that the connection is being used for special purposes (e.g. machine-machine, direct dialling or continuous connections, video telephony, call centre services, permanent monitoring services or extensive analogue data transmission), UPC reserves the right to suspend the service at any time, to restrict it or to take another suitable measure.
Calls to Swiss and foreign service and business numbers incurring costs (e.g. 0869x, 0878x, 18xy, 084x, 090x) and to Internet dial-up numbers and access numbers for prepaid and calling card offers are excluded from the Business Flatrate. Usage fees charged by service providers will also be billed to the customer.
