Your Android phone is always connected to the Internet, but you might not know that your other devices can take advantage of it, too. If you’re traveling with a tablet or a laptop that only has a Wi-Fi chip, your Android phone can magically be transformed into a Wi-Fi hotspot that your cellular-challenged devices can use to get access to the Internet.
And it’s not hard to do. With just a few taps in the Settings app you’ll be able to securely broadcast your signal to any device that may need it, letting you work as if you were connected to your home Wi-Fi. There are a couple caveats, however. For one, you’ll be using your phone’s data, so you probably shouldn’t use it to stream movies or download large files.

And finally, it can be a major battery drain on your phone, so make sure you have a battery pack handy.
