If you're stuck in a situation where you need a Wi-Fi connection, but can't get it anywhere else, chances are your smartphone can give you the boost you need. By setting up a hotspot through Wi-Fi or a USB cable, you can turn your phone into a source for internet that laptops, tablets, and other phones can use to get online. It may sound complicated, but you can be connected with just a few taps. Most of the major carriers offer tethering services, though your ability to create a Wi-Fi hotspot depends on your service plan and data allowance. One thing to keep in mind: tethering eats up battery life in addition to data. Investing in a portable charger is a good idea if you intend to use hotspot mode frequently. If you're ready to tether, here's how to turn your phone into a Wi-Fi hotspot.
