Q. I am using an ISDN service, what will it cost to dial-up?
A. The call cost will vary based on which carrier your ISDN service is with and what plan you're subscribed to. Please refer to your carrier's plan information and conditions for further details. Some carriers provide a capped cost plan for data calls. If you intend to be a heavy internet user we would strongly suggest you subscribe to such plans to ensure your call costs are deterministic. Please note, this section related to digital ISDN services and not regular 56k dial-up.
