What Phone Tethering is, And How to Use It

You might have heard of the term “phone tethering” before. In case you didn’t know what it meant, David Nield put together a guide explaining the term and how to use it.
We’re going to focus largely on wifi tethering here—creating a wifi hotspot from your phone or tablet—but you do have other options. If you’ve got a spare USB cable you can create a more stable connection between laptop and mobile device, or you can tether via Bluetooth, which is significantly slower but less taxing on battery life.
I’ll put an addendum here. Tethering depends on your carrier, and some carriers don’t allow it, like prepaid carriers. I used to use Net10 and I couldn’t use create a Wi-Fi hotspot.
