Right so on my Mac you can enable the iPhones WiFi Hotspot feature from the Wireless icon in the top right Menu.
I have an iPad Air (WiFi Only) and would love to be able to enable the phones Hotspot without pulling the phone out of my pocket every time. I want to use the iPad at work to find products on the companies website while on the sale floor.
Thanks in Advance!
As others have said, this is already a feature. It was introduced with iOS 8. As long as both your iPad and iPhone are on iOS 8 and connected to the same iCloud account, you can trigger it purely from the iPad. Simply open Settings > Wi-Fi on the iPad, and as long as your iPhone has Bluetooth enabled and is within range, you should see it listed above your other wireless networks (along with the signal strength, signal connection, and battery life on the iPhone). Tap it, and within a few seconds you should see the tethered icon appear at the upper left of the iPad's screen.
@silverblack mentioned connecting over Bluetooth instead of wifi, which is a different method of tethering that offers other benefits and a potential con. If you tether over wifi (as occurs if you tether using the instructions above), the connection will automatically cease if the iPad screen is off for a few minutes. If that happens, you'll need to re-initiate the tethering process to gain connectivity. If you pair by Bluetooth, the connection will last until the two devices are out of range, if the battery runs out on one device, or if you manually disable Bluetooth on one of the two devices. Because the connection requires your interaction only once to initiate and can last all day, I find it to be the preferable method of tethering when in a work environment that may require usage throughout the day. Because it works through Bluetooth the battery drain is minimal, so it's not a problem that the connection lasts all day. The only downside to tethering via Bluetooth over wifi is the connection speed. Depending on the network in your area, it's possible that your iPad won't be able to make full use of your LTE speeds, as the Bluetooth link won't be capable of transmitting at those speeds. This isn't an issue for web browsing, but if you're expecting to push or pull large files, you may want to consider tethering over wifi.
