Many users encounter a situation where their device runs out of space to download a new package, and their home network is unavailable or unstable. In such cases, a reasonable question arises: is it possible to perform the procedure without a wireless connection, and how to do it correctly? The answer is yes—there are proven methods to bypass the Wi-Fi requirement.
Modern versions of the operating system iOS They allow you to use your mobile network to download updates, if your data plan supports it. However, this method isn't suitable for everyone due to the large data volumes, which can exhaust your data plan in minutes. A more reliable and traditional option is to use a personal computer or laptop with the appropriate software installed.
It is important to understand that updating is a critical process that affects system files. Download interruption Unplugging the cable at the wrong time can lead to serious errors. Therefore, before beginning any manipulation, it's essential to thoroughly prepare, check the battery charge, and ensure the accessories are in good working order.
Using mobile internet for OTA updates
Starting with certain versions iOSApple has introduced the ability to download updates directly over a cellular network. This is convenient when you don't have a computer nearby or your Wi-Fi router is temporarily down. However, it's important to note that the distribution file size often exceeds 2-3 gigabytes, which is significant for limited plans.
To activate this feature, go to Settings and find the updates section. If the system offers the option to download via LTE/5G, then your carrier and current plan support it. Otherwise, the download button will remain inactive until you connect to a hotspot.

Settings → General → Software Updateon your device. - 📡 Click "Download and Install", ignoring the file size warning if it appears.
- 🔋 Make sure the battery charge is more than 50% or the phone is connected to a charger.
⚠️ Important: When downloading via a mobile network, make sure you have "Do Not Interrupt" or "Do Not Disturb" mode enabled to prevent an incoming call from disrupting your connection at a critical moment.
Once the download is complete, the system will prompt you to install the update immediately or later. Select "Install Now" if you're ready to reboot your device. The entire process can take 15 to 40 minutes, depending on your processor speed. iPhone and the speed of the cell tower signal.
Updating via a computer using iTunes
The classic and most stable method, used by professionals for many years, requires a PC or Mac with the program installed. iTunesThis method is ideal when mobile internet speed is slow and Wi-Fi is completely absent.
Before starting the process, make sure you have the latest version of iTunes installed on your computer. Older versions may not recognize new phone models or may not have the latest profiles for checking for updates. You can download the latest version from the official Apple website.
☑️ Check before updating
Connect your device to your computer using a cable. If this is your first connection, a prompt will appear on your smartphone screen asking "Trust this computer?" Be sure to tap "Trust" and enter the passcode, otherwise syncing will not begin. Then, select your device in the iTunes interface.
| Action | Description | Risks |
|---|---|---|
| Examination | Search for available software version | Minimum |
| Loading | Downloading the IPSW file | Depends on the network |
| Installation | Recording data to a phone | High at break |
In the device information window, click "Check for updates." If a new version is found, click "Download and update." The program will automatically download and install the firmware. At this point, do not disconnect the cable and do not run heavy applications on your computer.
Using Finder on macOS Catalina and later
Mac owners running macOS Catalina (10.15) and later should use Finder instead of iTunes. Device management functionality has been integrated directly into the file manager, simplifying the process but changing the familiar interface.
Open Finder and find the "Locations" section in the left sidebar. Your connected device should appear there. Click on it to see basic information. The interface resembles a simplified version of iTunes, but is more stable and faster.
Click the "Check for Updates" button. If the system detects a new version of iOS, a notification will appear. The process is exactly the same as with iTunes: you agree to the terms and conditions, and the download begins. The main advantage is that there's no need for a separate, heavy app.
What to do if the computer doesn't recognize the iPhone?
If Finder or iTunes isn't responding to the connection, try replacing the USB cable with a genuine or MFi-certified one. It's also worth checking that the Apple Mobile Device Support driver is installed (on Windows) and that all macOS updates are up to date. Sometimes, simply restarting both devices helps.
Please remember that during installation, your computer acts as a gateway for downloading data. If your computer's internet connection is unstable, the process may freeze during the verification or download phase. In this case, it's best to abort the installation and try again with a more stable connection.
Manual firmware installation (IPSW files)
This method is intended for advanced users who want full control over the process or have encountered errors with automatic updates. It involves downloading the firmware file first (.ipsw) manually and its forced installation.
First, you need to find and download the latest firmware file for your specific model from a trusted resource. It's important to select the version signed by Apple, otherwise installation will fail. The file will be saved to your computer's hard drive.
To start the process, a special key combination is required when pressing the update button:
- 💻 On Windows: hold down the key
Shiftand click "Update iPhone". - 🍏 On Mac: Hold down the key
Option(Alt) and click "Update iPhone".
A file selection window will appear. Find the file you downloaded earlier. .ipsw file and confirm the action. This method is useful because it avoids re-downloading if the connection is interrupted—the file is already on the disk. It also often helps fix errors that occur during a standard update.
⚠️ Warning: Using IPSW files from untrusted sources may result in your computer being infected or installing a modified operating system. Download firmware only from official servers or verified archives.
Troubleshooting common upgrade issues
Even if you follow all the instructions, technical difficulties may arise. Most often, users encounter connection errors or insufficient space. Understanding the causes of these problems helps quickly resolve them without losing data.
If the process gets stuck at the "Checking for updates" stage, try restarting your computer and router (if you're using one for distribution). You should also check your antivirus and firewall software—sometimes they block the connection to Apple servers. Temporarily disable them for this process.
The "Not enough space" error can be resolved by deleting iTunes' temporary files. On Windows, these are located in the user folder; on Mac, they're in the library. Clearing the cache often frees up several gigabytes needed to unzip the archive.
Create a backup before starting work
Any software intervention carries a minimal, but existing, risk of data loss. Before updating without Wi-Fi, it's crucial to create a full backup. This will allow you to restore your contacts, photos, and settings in the event of a failure.
You can back up via iCloud if you have access to another network, or locally to your computer. A local copy is more reliable and faster, as it doesn't rely on internet speed during the restore process. In iTunes or Finder, select "Back Up Now."
After successfully creating a backup, we recommend checking its presence in the list of devices. Ensure the date and time of the last backup are correct. Only then can you safely proceed with the system update.
