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.
Turn on Wi-Fi Hotspot With iOS Devices
To set up a personal hotspot on your iPhone or iPad (Wi-Fi + Cellular), go to Settings > Personal Hotspot > Allow Others to Join and toggle it to on (if you don't see Personal Hotspot in Settings, tap Cellular > Personal Hotspot). Make note of the Wi-Fi password.
Open the Wi-Fi menu on the device you need to connect to the internet. Look for your iOS device (ex: PCMag's iPhone), select it, then enter the password that appears on your iPhone's Personal Hotspot screen.
iPhone and iPad also provide alternate ways to connect with your hotspot, including Bluetooth and direct USB connection. You may need to turn on Maximize Compatibility to make these connections work, but keep in mind that the quality of your connection may be impacted.
Once your secondary device is connected, you should now be able to surf the web (and consume mobile data). To disconnect, toggle Personal Hotspot to off on your iOS device.
