7-4 Traveling Tips
Using Your Modem
Whether you are on a business trip or vacation, connecting to the Internet while you
travel can be expensive and frustrating unless you are prepared. Here are some tips on
how to avoid frustration and expense while on the road.
1. Before leaving home, check with your Internet Service Provider to see if it has:
!
a local access number at your point of destination.
!
a toll-free number that can also save you money.
In the absence of a local ISP access number or toll-free number, charging the call to
your home phone can be less expensive than charging the call to your hotel room.
2. Prepare your system for phone line access in another country.
!
Line access outside of a hotel may require the addition of a “9” preceding the
phone number string. Be sure to modify your dial-up connection, as required.
!
To circumvent unusual dial tone sounds sometimes encountered in hotels, you
may have to modify a modem configuration setting to ignore the dial tone. For
details specific to your modem, refer to the AT command section of your
modem user’s guide.
3.
Always check the phone line to determine whether or not it is digital vs. analog.
NEVER use your modem with a digital phone line. The internal modem in your
NEC Versa system has built-in protection that detects the presence of a digital
phone line and displays a warning message to alert you.
4. Use AT&T’s Worldwide Calling Guide, a resource that provides instructions for
dealing with unfamiliar phone systems. For more information about the calling
guide, access the web site at http:/www.att.com/traveler/.
