"Can I update my iPhone with unstable Wi-Fi or no Wi-Fi?"

Sometimes, you may encounter a situation where the Wi-Fi is unstable or the Wi-Fi is not connected, and it will be difficult to complete the iOS update on the iPhone. Then you must be wondering how to update iOS without WiFi. To be sure, iPhone updates can be done without WiFi, whether it is iOS 17/16/15/14 or other iOS versions.

In fact, although you can update your iPhone to the latest version of iOS 17/16/15/14 when there is no stable Wi Fi connection or no Wi Fi at all, you'll need to connect your iPhone to an Internet connection other than Wi-Fi to do the update process. That is, you need to have your computer connected to the Internet or cellular mobile network, and make sure your iPhone has enough storage space to get the latest update iOS 17/16/15/14.

Here's a look at how to update your iPhone without Wi-Fi. We have summarized 3 effective methods for you, hoping to be helpful to you.

Method 1 Update iOS with Mobile data

As we all know, updating an iPhone to the new iOS 17/16/15/14 requires an Internet connection. Therefore, the easiest way to update iOS without Wi-Fi is to complete the update via cellular data. The detailed steps are as follows.

Step 1 Turn on your iPhone and enable cellular data.

Step 2 Go to "Settings" > "General" > "Software Update", and click on it to start searching for updates on your iPhone. After finding the available updates, click on the "Download and Install" button and follow the prompts.

Step 3 After the download is complete, you will see a pop-up prompt to install iOS immediately or later. Please click "Install Now". Currently, you can update to iOS 17.

Step 4 Your iPhone screen will go black during installation and you will see the Apple logo and installation status. Once the installation is complete, your iPhone will reboot and you'll be prompted to enter your passcode to use the device immediately.

Tip: Make sure your device has an adequate cellular data plan. Also, your iPhone's battery needs to be at least 50% charged. Because the process of updating the iPhone consumes a lot of data and battery.

Method 2 Perform iOS 17/16/15/14 Updates Using iTunes without Wi Fi

Another way to update iOS without Wi-Fi is to use iTunes. Use the latest version of iTunes on your PC, then follow these steps to update your iPhone to the latest iOS, such as iOS 7.
