When you use tethering to set up a Personal Hotspot, anywhere your iPhone or iPad can access a cellular signal, your computer can get online too. Personal Hotspot requires an iPhone 3GS or later or a 3rd-generation Wi-Fi + Cellular iPad or later and a compatible cellular service provider. Before you can set up a Personal Hotspot, contact your cellular provider to add this service to your account. There is usually a fee for the service. Some cellular providers do not support tethering, but AT&T, Verizon, Sprint, Cricket, US Cellular, and T-Mobile support it. Turn on Personal Hotspot After you set up the service with your cellular provider, following that company's instructions, it is time to turn on the Personal Hotspot service on your iPhone or Wi-Fi compatible iPad. heshphoto / Getty Images To set up Personal Hotspot on your iPhone or iPad: Tap Settings on the Home screen. Select Cellular. (Some iOS versions skip this step.) Tap Personal Hotspot. (In iOS 13, you must also tap Allow Others to Join). Tap the slider next to Personal Hotspot to the On/green position to turn on the feature. If Bluetooth or Wi-Fi is turned off on your iPhone, you are prompted to turn them on. Tap the Wi-Fi Password field. Your password is set up as your mobile phone number by default, but change it to something appropriate that is at least eight characters long. The Wi-Fi password, in this setting, isn't related to your Apple ID or your usual Wi-Fi password. It is for use only with Personal Hotspot. Deactivate the Personal Hotspot when you aren't using it by moving the slider to the Off/white position to reduce your security risk and battery drain. Making Connections You can connect your iPhone or iPad to your computer (or another iOS device) to provide it with access to your cellular connection in three ways. Wi-Fi: Both devices must have access to the same Wi-Fi network. On your computer, select the name of the iPhone or iPad from the Wi-Fi settings.Bluetooth: To connect by Bluetooth, the computer (or another iOS device) must be discoverable. On your iOS device, go to Settings and turn on Bluetooth. Select the device you want to tether to the iOS device from the list of discoverable devices.USB: Plug in your iOS device to your computer using the cable that came with it. To disconnect, turn off Personal Hotspot, unplug the USB cable or turn off Bluetooth, depending on the method you use. In iOS 13, you can use Control Center to turn Personal Hotspot on or off quickly. Hard press the airplane icon to expand the options and then tap Personal Hotspot. Using Instant Hotspot If your mobile device is running iOS 8.1 or later and your Mac is running OS X Yosemite or later, you can use Instant Hotspot to reach your Personal Hotspot without entering a password.
