You can use a cellular connection if your plan allows, or connect your device to a computer. iOS update This is a critical process that ensures the stable operation of the device. In this article, we'll cover in detail all the available methods for installing new firmware without using a wireless network.
Before you begin, make sure your device is ready for the procedure. It must have sufficient battery power and sufficient free memory to meet system requirements. Interrupting the installation process at the data writing stage may result in complete device failure and the need to restore the device via DFU mode. Let's look at each method in detail so you can choose the one that best suits your situation.
Using 4G and 5G mobile network for downloading
Starting with certain versions iOSApple now allows downloading updates larger than 200 MB over a cellular network. Previously, this was impossible without a Wi-Fi connection, but modern 4G/5G plans and speeds have made this method quite viable. To use this method, make sure your mobile data is enabled and you have a stable signal.
Go to your device settings to check if this option is available. The system will automatically offer to download the update package if it deems your connection fast enough. However, keep in mind that the data usage can be significant, so keep an eye on the remaining data allowance in your plan.

It's important to note that this feature may be limited in some regions or with certain carriers. If you don't see the mobile download button, it means your carrier is blocking this traffic or your iOS version is too old to support this feature. In this case, proceed to the next method.
Updating via a computer using iTunes and Finder
The classic and most reliable method, which has been used for many years. Connecting to a computer allows you to not only update the system but also create a full backup of your data before starting the process. For Windows and macOS Mojave or earlier, you will need the program iTunes, while on new macOS the control is carried out through Finder.
First, you need to prepare the cable. Use the original wire. Lightning or USB-C, as cheaper alternatives may not provide stable data transmission. The computer must have internet access to download the firmware file, but the iPhone itself can be connected locally.
⚠️ Important: If you're using Windows, make sure you have the latest version of iTunes installed from Apple or the Microsoft Store. Older versions may not recognize new iPhone models or the latest iOS versions.
The update process is as follows:
- 💻 Connect your iPhone to your computer via USB cable.
- 🖥️ Open iTunes (or Finder on Mac) and select your device.
- 🔄 Click the "Check for updates" button in the "Overview" section.
- ✅ Click "Download and Update" to start the process.

Connection interruption At this point, a restore error may occur. After the installation is complete, your iPhone will automatically boot up with the new operating system.
☑️ Ready to update via PC
Create a local backup before updating
Although the question was about updating without Wi-Fi, you can't ignore backups. iCloud backups require a wireless network to create, so the only option is to save your data locally on your PC. This is critical, as if the update fails, you'll be able to restore your contacts, photos, and settings.
When connecting to a computer, select "This PC" as the backup location. You can also set a password to encrypt the backup to preserve your Health data and access keys. Without encryption, this sensitive data will not be saved.
The backup process can take anywhere from 10 minutes to an hour, depending on the amount of data. Make sure your computer doesn't go into sleep mode during the process. Once completed, the date of the last backup will appear in iTunes or Finder.
| Parameter | Via iCloud (Wi-Fi) | Locally (PC) | Impact on update |
|---|---|---|---|
| Speed | Depends on the router | Depends on the USB cable | High speed PC is preferable |
| Data volume | Limited by tariff | Limited by PC disk | Does not affect the firmware process itself |
| Reliability | Average | High | Reduces the risk of data loss during a failure |
| Availability | Wi-Fi only | Anywhere from your PC | The only option without wireless network |
What to do if the computer doesn't recognize the iPhone?
If iTunes isn't responding to the connection, try changing the USB port (preferably the ports on the back of the system unit), replacing the cable with an MFi-certified one, or restarting both devices. You may also need to update your Apple Mobile Device Support drivers in Windows Device Manager.
Troubleshooting low memory issues
A common issue during an update is a message stating that there isn't enough space on the device. The update file can be several gigabytes in size, and the system needs space to unpack and install it. If you're updating via a PC, the computer handles some of the work, but temporary files are still created on the phone.
To free up space, you can use the built-in iOS recommendations. Go to Settings → General → iPhone StorageThe system will offer to remove rarely used apps or clear the message cache. It's also worth checking the "Recently Deleted" folder in your photo albums, as photos are stored there for another 30 days and take up space.
If cleaning doesn't help, you can try deleting the Settings app (don't worry, it's a system cache and will be restored) or temporarily uninstalling heavy games and streaming services with offline content. You can download them again after the update.
- 🗑️ Delete apps you don't use.
- 📸 Clear the "Recently Deleted" album in Photos.
- 💬 Delete old conversations with attachments in iMessage/WhatsApp.
- 📂 Move photos and videos to your computer before updating.
⚠️ Note: The storage management interface may differ on different iOS versions. If you can't find a specific option, check Apple's official help, as the menu layout sometimes changes in new releases.
Recovery mode and DFU in case of errors
Even if all the necessary steps are met, the update process may not go smoothly. If your iPhone is stuck on the Apple logo or a screen with a cable and laptop appears, the device has entered recovery mode. This is a normal situation and can be resolved by reconnecting it to the computer.
To enter recovery mode manually (if the screen is unresponsive), use a combination of buttons. On models with Face ID, quickly press and release the volume up button, then the volume down button, and then hold the power button. On models with a Home button, press and hold the power button and the Home button (or volume down for iPhone 7/8).
The computer will detect the device in recovery mode and offer the options "Restore" or "Update." Selecting "Update" will attempt to reinstall iOS without losing your data. If that doesn't work, you'll have to select "Restore," which will erase all data but restore your phone.
Frequently Asked Questions (FAQ)
Is it possible to update an iPhone via a hotspot from another phone?
Yes, this is a great option if the second phone has a stable 4G/5G connection and an unlimited data plan. Create a hotspot, connect your iPhone to the Wi-Fi network created by the other phone, and update your iPhone using the standard settings. This is considered a Wi-Fi connection, but the data traffic is routed through the second device's mobile network.
How long does it take to update iOS via USB?
The time depends on your computer's internet speed and the speed of writing to your iPhone's flash memory. Downloading typically takes 10-20 minutes, and installation itself takes another 10-15 minutes. The entire process rarely exceeds 40-50 minutes on modern devices.
Will my data be lost when I update via iTunes?
When you select "Refresh," your data is preserved. It is only deleted if you select "Restore" or if the process is interrupted during a critical stage of writing the file system. This is why creating a backup before starting is essential.
Why does iTunes report error 3194 or 4013?
Error 3194 is usually related to an antivirus program or hosts file blocking Apple servers, while error 4013 often indicates hardware issues with the USB cable or port. Try changing the cable, port, or computer to resolve the error.
