Collect and Enter Information
Collect User information from your local ISP:
lUser Name (enter exactly as given)
lPassword (case sensitive)
lNumber (enter 7 or 10 digits as necessary to connect to this number from your home) PLEASE NOTE: Some areas require your phone to dial a prefix such as 1 or 9 to access this number. These settings must be placed in the Number box as needed or your device will not connect. NOTE: Before adding a 1 be sure to check with your local phone company to insure there will be no toll charges incurred. As always, you are responsible for determining whether a telephone access number is accessible by a local phone call in your area and for any long distance and toll charges that you may incur in connecting to the network.
