Depending on your carrier, the Personal Hotspot feature comes enabled (or you might have to enable it). Personal Hotspots on the iPhone are what turn your iPhone into a modem. Of course, there are variations though. Interestingly though, a lot of people do keep asking how to use the iPhone as a modem. If you’re looking for that information, we’ve got it here.
How to Use the iPhone As a Modem
You can use the iPhone as a modem for your laptop/desktop by connecting it to the system. Step #1. Go to Settings → Personal Hotspot. If Personal Hotspot isn’t visible or if it’s not activated, you might have to call up your carrier (AT&T, Verizon, etc.) and ask them to enable the service for your number. Usually, it comes enabled by default. Step #2. Turn this feature ON Your iPhone becomes an active hotspot only when you turn ON personal hotspot. This applies even when you’re connecting it “wired.” Step #3. Now connect your iPhone to your computer via the USB cable. Step #4. Forget iTunes. That’s not what we’re after so if it opens up, ignore it or close it down. Step #5. Under your network settings (accessible from the taskbar), you should now see your iPhone listed as a network device. Click on it. Step #6. Once connected, you should now be able to access the 3G/4G connectivity via your iPhone. It begins to work as a modem. This is a particularly simple method. Of course, if you wanted to use it as a Wi-fi modem, you’ll simply turn on the Wi-fi receivers in your laptop and then search for your device. For Wi-fi, your iPhone will be listed as a network device again. This time though, you’ll have to supply the password. You can find this password (and edit it, if needed) under Settings → Personal Hotspot. That’s all, folks!
