If you’re on business and are visiting one of your company’s other locations, you can probably use a computer there to check your business email. Depending on the company’s Internet Acceptable Use Policy, you may or may not be allowed to check your personal email.
Remember that the Internet Acceptable Use Policy is a corporate policy. It is designed to tell you what you can and can’t do. The company network may, or may not, prevent violations of the policy. Just because the network does not block you from doing something or from going somewhere on the Internet, do not assume that it is permitted.
Many hotels have a business center that is open to the hotel’s guests. Sometimes, the computers are available for use for free. Other hotels will charge you based on the time that you use it. Remember that this is a public computer and some scumbag may have installed a software or hardware keylogger on the computer. This type of computer would be my last choice for conducting business or personal business.
Airports sometimes have a similar business center. Internet Cafes, providing computer use and coffee/drink/food are available in some cities and some parts of the world.
If you’re visiting friends and family, you might request their permission to use their computer to check your email. Most Internet Service Providers provide you with the ability to access your email via a web browser. The URL is usually http://webmail.example.com , such as http://webmaiil.cox.net and http://webmail.bellsouth.net .
