While traveling, it is often vitally important for you to have access to the Internet. Of course, a clear Wi-Fi signal is not always available, and some services actually require you to pay to access the Internet (case and point, many U.S. airports charge for this service). To combat this, there are many options for an individual to access the Internet, without paying for a specific service, as the Internet is free with several different tools and tricks).
First, check for any wireless Internet services on the public transportation you are in (such as the bus, train or airplane). More and more public transportation services are now including Wi-Fi in order to bring in customers. If there is no unlocked wireless network on the transportation service, there are a few other options available to you.
If your mobile phone has a mobile hotspot creator, it is possible to create your own Internet connection. Simply activate the mobile hotspot option on the device, then connect to the wireless network created by the phone with your computer. Many new mobile phones have this feature and allow up to five different laptops and other products the ability to connect to the service. Of course, in order to create the mobile hotspot, the device does need to have access to a 3G or 4G network. Without this connection, the mobile hotspot does not connect.
There are external tools you can connect to your computer in order to access the Internet also. These devices work through your wireless service provider and plug into the computer. As long as there is a cell phone signal, the computer is able to access the Internet. With the computer connected to the mobile service, you can connect to the Internet and perform many of the same tasks, although the signal connection is generally slower than a standard Wi-Fi signal.
