So, if you satisfy these conditions, here is a step by step guide on how to download software updates on the iPhone using mobile data.

How to Download Software Update on iPhone Using Mobile Data
Step #1. Launch the Settings app on your iPhone and completely switch off Wi-Fi, Bluetooth, and Personal Hotspot. Do not use Control Centre for this.
Step #2. Connect your iPhone to the Mac via proper cable.
Step #3. Inside the Settings app on iPhone, tap on Personal Hotspot.
Step #4. Turn on the toggle for Allow Others to Join. From the pop-up, select USB Only.

Step #6. Click on Sharing and then click on Internet Sharing. Do not click on the small box before Internet Sharing.
Step #7. Click the toggle dropdown menu for Share your connection from: and select iPhone USB. (If you do not see iPhone USB here, look for the solution at the end of these steps.)
Step #8. For To computer using: tick the box before Wi-Fi to select it.
Step #9. Now, on the left side, click on Internet Sharing and then click inside the small box before it. A pop-up will appear from top of the window.
In the pop-up, the default values are perfect. See image above. In the password section, input any password. This is the Wi-Fi password of your Mac’s hotspot. Click OK → Click Start to confirm.
You will see an upward-facing arrow in the Wi-Fi icon of your Mac. Your Mac is now using your iPhone’s mobile data and sharing it as Wi-Fi.
Note: If you do not see an option to set a password in Step #9 and only see Start, this means you have used this feature in the past. To set a password, click on the small box before Internet Sharing to turn OFF internet sharing. Next, from bottom right, click on Wi-Fi Options… and set your password. Finally, click inside the small Internet Sharing box to start sharing your iPhone Mobile Data Hotspot via Wi-Fi.
Now let us connect the iPhone with this hotspot and install the iOS update.
Step #10. Launch the Settings app on your iPhone and tap Wi-Fi.
Step #11. Turn on the toggle for Wi-Fi and let it search. When you see your Mac’s name, tap on it, and enter the password you created in Step #9 above. After a successful connection, you will see the Wi-Fi logo at the top of the screen on your iPhone.
Step #12. Now head over to General → Software Update, and download and install the pending iOS update.
Do not See iPhone USB in Step #7?
Most likely, you will see the option, but if you do not see iPhone USB in Step #7 follow this trick.
Turn on Personal Hotspot on iPhone, connect it to Mac, and click on Network in Mac’s System Preferences.
Click on the plus (+) icon at the bottom left. Click on Interface and click on iPhone USB from the list. Now click on Create. Finally, click Apply from the bottom right and try from Step #7 again.
Interesting Observation related to Downloading iPhone Software Update over Mobile Data
It is like a full circle. Your iPhone’s mobile data is going inside your Mac, and then from there is comes out as Wi-Fi to which you connect the same iPhone. Interesting. Isn’t it!
I discovered and used this trick in my early days when the mobile network provider I switched to gave 4GB 4G data every day.
Some Points to Note When You Download iOS Update over Cellular Data
- Most likely, this Wi-Fi would be slower than your mobile data
- If pending updates or some download are running on Mac, it might utilize this iPhone USB data in the background. It may quickly exhaust your limit. So make sure apps or files are not downloading or updating in the background on your Mac. This would also ensure faster speed for you to download your iOS update
- Use this technique only to download small iOS updates, and for significant iOS updates, try finding proper Wi-Fi
- You can not use AirDrop on Mac as long as you are sharing the internet from it. This is similar to the iPhone, where you can not use AirDrop when you have devices connected to its Personal Hotspot
Why Apple Does Not Allow iOS Updates on iPhone Over Cellular Data
When the iPhone was launched in 2007, it was available only on AT&T. Also, even when future models were available on other carriers, the mobile data was expensive, and going over the limit would exponentially skyrocket the bill.
Maybe this was the reason Apple had restrictions even on the size of the App you could download over mobile data. Just recently, Apple has allowed downloading apps over 200 MB in size from the App Store.
If there are no limitations or too much work on the fundamental level of iOS, then in the future, we may be allowed to download software updates straightforwardly using Cellular data. As of now, the above trick is there for you.
This was how to download an iOS software update on the iPhone using Mobile Data. Now it was a workaround, and I hope you enjoyed reading this.
Finally, you can follow this know-how even if you have a Windows 10 device. I will make a guide on that, too, and update it here. However, as of now, I have faced multiple issues with the version of Windows 10 I have on a spare computer.
