How do I use my smart phone as a Wi-Fi hot spot?
Published February 05, 2015
Q. In 30 best travel gadgets for your summer vacation you advised setting up your own hot spot by using your phone as a personal Wi-Fi hot spot so that other gadgets can get online when no Wi-Fi is available. Will you please explain how we can do that?—Floyd Williams, Mercer Island, WA
A. Many phones and tablets with 3G or 4G data capability have an optional function, found among the wireless settings, that enables their built-in Wi-Fi radio to work in reverse. When chosen, the feature lets the phone appear to other devices as a private Wi-Fi hot spot. It passes the data to the cellular network. Usually, you must pay a monthly fee for that in addition to the usual cellular data charges, and the device’s battery could drain faster when the feature is in use.
