Checking e-mail from the road can get expensive when every call to your Internet service provider (ISP) is long distance. A frugal alternative is HomeGate, a service that provides subscribers with local access numbers in most major cities around the world. Call that number, and seconds later you're logged on to your home ISP. HomeGate's cost? Eight cents per minute for calls within the United States; 50 cents per minute for international calls. There's also a $5 monthly subscription fee, but it's not assessed during months when you don't use the service. For a free 30-minute trial, sign up at HomeGate's Web site at http://www.homegate.net .
