⚠️ Note: The menu interface and item names may vary slightly depending on the operating system version and your device model. Always check the manufacturer's official manuals for the latest information before making any system changes.

Using mobile internet for OTA updates

Starting with certain versions iOSApple has introduced the ability to download updates directly over a cellular network, bypassing the need to search for a wireless access point. Previously, the system required Wi-Fi to download firmware files, but this barrier has now been removed for most modern models. However, this process is not automatic and requires manual activation of a special setting in the device's menu.

To get started, you need to go to Settings and find the section responsible for software. Typically, the path looks like this: Settings → General → Software UpdateIf an update is available but your phone requires Wi-Fi, you'll see a notification. At this point, find the option to enable downloading via cellular data and toggle it to on. The system will then begin downloading the update package using your current mobile signal.

It's important to keep in mind that download speed will directly depend on the network coverage in your area. If you're in a weak signal area, 4G or 5GThe process can take a considerable amount of time, and the phone may periodically interrupt the download to conserve battery power. It is recommended to keep the device connected to a power source or ensure the battery is at least 50% charged before beginning the procedure.

An important consideration is traffic volume. Update files can weigh between 2 and 6 gigabytes, which is significant for data plans with limited data allowances. If your carrier blocks or limits speeds after your data plan is used up, downloads may stall or be extremely slow. In such cases, it's best to use the alternative methods discussed below.

Personal Hotspot: Create a Personal Area Network for iPhone

If direct downloading via settings doesn't work or your data plan doesn't allow for gigabytes on your primary device, you can use tethering. This method involves using another smartphone or tablet with unlimited data as a signal source. You create a local network to which your iPhone connects, and the system treats this connection as a standard Wi-Fi network, allowing you to start downloading.

To use this method, you'll need a second device (Android or iOS) with an active data plan. On this device, you'll need to enable the "Tethering" or "Personal Hotspot" feature. Once enabled, the network name and password will appear on the screen. On your iPhone (which requires the update), go to Wi-Fi settings, find the newly created network, and enter the password to connect.

Once the connection is successful, the Wi-Fi icon in the status bar will be replaced by the tethering icon (two paper clips), or the Wi-Fi icon will remain, but traffic will go through the donor's mobile network. You can now return to the menu. Software update and start the process. The system will detect an active internet connection and begin downloading files without any additional restrictions.

  • 📱 Make sure the donor device has data enabled and a strong network signal.
  • 🔋 Tethering uses a lot of battery, so keep both devices charged.
  • 🔒 Use a strong password for your hotspot to prevent strangers from connecting to your network.
  • 📶 Place devices close to each other for maximum signal quality.

This method is especially convenient when you're away from home but have a colleague or friend with a good data plan nearby. It also allows you to bypass any carrier blocking on your primary device, as it appears to your iPhone as a regular Wi-Fi connection. However, be aware that devices can heat up when actively transferring large amounts of data.

Updating via computer: iTunes and Finder

The classic and most reliable way to update iPhone Without using Wi-Fi on the phone itself, connect to a computer. This method doesn't consume your smartphone's mobile data and provides a more stable connection, minimizing the risk of errors when downloading files. The computer takes over the task of downloading the firmware, offloading the phone's processor and saving battery life.

For owners of computers with an operating system macOS Catalina If you have an iOS device or later, you need to use the built-in Finder app. If you have an older version of macOS or a Windows computer, you'll need iTunes. Make sure your computer has the latest software installed to avoid compatibility issues when working with newer versions of iOS.

The process begins by connecting your device to your computer using an original or certified Lightning to USB-C cable. Once connected, you may be asked to trust the computer on your smartphone's screen by entering a digital passcode. In Finder or iTunes, select your device in the sidebar and go to the "Summary" or "General" tab.

Path to the update button: Browse -> Check for update -> Download and update

By clicking the "Check for Update" button, the system will contact Apple servers. If a new version is available, the "Download and Update" button will appear. The computer will download the full system image and install it on the phone. Unlike the wireless method, there is no file size limit, and the process will only be interrupted if the cable is cut or the computer is turned off.

Troubleshooting download issues and network errors

Even with internet access, the update process may encounter technical obstacles. Users often encounter a situation where the download begins but then freezes at the "Update Evaluation" or "Downloading" stage. This can be caused by a full temporary file cache or a network settings conflict. In such cases, resetting the network settings can help, but this should be done with caution.

Before resetting, make sure you remember your Wi-Fi network passwords, as they will be deleted from your device's memory. Go to Settings → General → Transfer or reset iPhone → Reset and select "Reset network settings." After rebooting, your device will have clear network configurations, which often resolves connection errors to update servers.

Another common issue is a lack of free space. To install an update, the system requires temporary space, which may exceed the size of the firmware file itself. If your iPhone doesn't have enough memory, the download over a mobile network may not begin at all. In this case, you need to free up space by deleting unnecessary apps, photos, or videos.

⚠️ Important: Do not interrupt the update process if the progress bar shows any activity. Interrupting the installation during the final stages may result in the system becoming unbootable and will require a computer restore in DFU mode.

What to do if the update is stuck at 1 minute?

If the time indicator shows "1 minute remaining" for more than 15 minutes, this doesn't always indicate an error. The system is verifying the integrity of the files. However, if the process takes more than an hour, try restarting your device and restarting the update, after first disabling and re-enabling airplane mode.

Optimizing traffic and battery consumption

Downloading a multi-gigabyte update is stressful not only for the network but also for the battery. The device's processor works in overdrive to unpack and write data, which causes heat and rapid battery drain. To minimize the risk, it's recommended to close all background apps before starting the process. This will free up RAM and reduce the load on the processor.

It's also worth disabling photo and cloud syncing during the update. If iCloud Photos The iOS app will start uploading large videos to the cloud simultaneously with the system update. This may cause the device to overheat and the connection to become unstable. It's best to wait until the iOS installation is complete before resuming active use of cloud services.

Using original cables and power supplies is critical when updating without Wi-Fi, especially if you're using tethering. Unstable power can cause the screen or the device itself to turn off at a critical moment. If you're updating over a mobile network, enable Do Not Disturb mode to prevent incoming calls from interrupting the installation process.
