You should know how to turn your phone into a wi-fi hotspot — it’s a good 21st-century life skill. After all, you’ve probably been in a situation where the internet dies and you can’t do much on your tablet, laptop or desktop computer; but, because your smartphone still gets LTE, you can browse the web and check your Instagram or Twitter feeds. It’s a fairly common frustration, and until LTE-equipped laptops become more common, it’s likely to stay one.
Fortunately, turning your smartphone into a wi-fi hotspot is pretty simple. There are some conditions to know about first. You probably want to have an unlimited data plan, as a mobile hotspot can burn through data like no other. And there are some cell carriers that require a hotspot plan or have a tethering charge. Also, using your smartphone as a hotspot will drain its battery rather rapidly, so you might want to have your smartphone connected to a portable power bank or plugged into a wall outlet.
Both iPhone and Android smartphones can function as a wi-fi spot, though the steps to turn each into one varies slightly. Here’s what you need to know.
