I want to update to iOS 16, but I am not in a place where I can get WiFi. I have several gigs of LTE, plenty for a 250meg update. Is it possible to update iOS without WiFi? Can I update my iPhone using cellular data?

We all know that an iOS update requires stable internet connection. And Apple also restricts the download of the iOS update over a cellular data connection. That means you can only update iOS over the air via Wi-Fi.

It would be frustrating when you want to update your iPhone to the newest iOS 16 but suffer from unstable WiFi or there is no WiFi service available. Luckily, there are still several workarounds to update iOS without WiFi.

In this article, we will share 3 practical ways that you can update iPhone to iOS 16 without using a Wi-Fi connection.

Way 1: Update iOS 16 without WiFi: Using Mobile Data

Although Apple doesn’t support to download the iOS 16 update file with cellular data, there is a workaround for that. If you have spare phone and it has enough data plan, you can still update your iPhone by creating a personal hotspot.

The Personal Hotspot behaves just like Wi-Fi even though it uses cellular data and will enable you to do the update. Follow these simple steps:

  1. On your other iOS device, go to Settings > Cellular > Personal Hotspot and turn it on. If it is an Android device, go to the Settings to turn on Mobile Hotspot.
  2. Back to your iPhone that you’d like to update, go to Settings and turn on Wi-Fi, find the personal hotspot and connect to it using password.
  3. Then back to Settings > General > Software Update to check for the available iOS update, tap “Download and Install” to begin the iOS 16 updating process.

If there is no spare phone available, you can also update your iPhone without Wi-Fi using iTunes or Finder on computer.

Here’s how to use iTunes or Finder to update iPhone to iOS 16:
