The dial-up numbers above are the local calling numbers according to the latest information that we have available. They are not guaranteed to be a flat-rate local call. That determination can only be made by your local telephone provider. All information returned here should be verified with that provider before it is used. Before you use any dial-up number for Internet access, you must contact your local telephone service provider to verify if the number in question would be a toll-charge call for you. You can reach your local operator by dialing "0". Let the operator know the telephone number that you are dialing from and the number that you are dialing to. The operator will then verify whether or not the number is a toll-charge call for you. It is your sole responsibility to verify this information. We are not responsible for any charges you may incur.
