How to update an iPhone without Wi-Fi if the update is larger than 200 MB: 5 working methods

iOS updates often exceed 200 MB, and Apple By default, it blocks downloads via mobile data. This restriction protects users from unexpected data charges, but creates problems when a stable connection is not available. Wi-FiFor example, you're traveling, at your vacation home, or in a location where your home network isn't available, and the update is critical for security or new features.

Fortunately, there is a way around this limitation—and more than one way. In this article, we'll look at 5 legal methods, how to update iPhone without Wi-Fi, including hidden settings iOS, usage Mac/PC, a mobile hotspot, and even bypassing operator restrictions. Important: Some methods require preparation, so read carefully—especially if you limited tariff with payment for over-limit traffic.

Why does iPhone block downloading updates >200 MB over mobile data?

Apple There's a reason this restriction was introduced. Here are the key reasons:

• 📶 Saving traffic: Mobile networks are often slower and more expensive than Wi-FiA 1–2 GB update can consume the entire package in minutes.
• 🔋 Risk of battery discharge: Downloading large files over 4G/5G uses up battery faster than Wi-Fi.
• 🔄 Connection stability: An interrupted update may result in a brick (inoperable device).
• 💰 Operator policySome mobile plans block large downloads or charge extra fees.

However, these reasons are not always relevant. For example, if you have unlimited tariff With 5G and a 100% battery, the limitation becomes meaningless. Fortunately, it can be circumvented—and we'll show you how below.

Method 1: Enable downloading via mobile data in iOS settings

WITH iOS 13 Apple Added a hidden option that allows you to download updates larger than 200 MB over a cellular network. Here's how to enable it:

1. Open Settings → Cellular (or Mobile data).
2. Scroll down to the block Data parameters and select Cellular data (or Mobile data again).
3. Activate the switch Allow large downloads (in some versions - Downloading via cellular network).
4. Return to Settings → General → Software Update and start the download.

⚠️ Attention: After activating this option iPhone will load All large files over the mobile network, including app updates from App StoreDisable it after updating to avoid unexpected data usage.

Check your remaining traffic in your operator's personal account

Connect the charger (battery should be >50%)

Disable your VPN (it may be interfering with your connection)

Close background apps (especially messengers and streaming services)

Method 2: Use iPhone as a hotspot for another iPhone

If you have a second one iPhone (or iPad) With Wi-Fi, you can "trick" the system by sharing the internet from one device to the second. This method works because Apple does not block downloading updates through personal hotspot (even if the source Internet is mobile).

Instructions:

1. On the first iPhone (with mobile internet) turn on Modem mode (Settings → Tethering).
2. On second iPhone (which needs an update) connect to the access point of the first one through Settings → Wi-Fi.
3. Run the update on the second device via Settings → General → Software Update.

🔹 Advantages of the method: The update is done via Wi-Fi (albeit virtual), so there is no risk of interrupting the download due to unstable 4G.

🔸 Minus: A second one will be needed iPhone/iPad and additional traffic consumption on the first device.

What if I interrupt an iOS update via a hotspot?

If the connection is interrupted while the firmware is downloading, the iPhone will attempt to resume the process the next time it connects. However, if the connection is interrupted installation (After booting, during the "Preparing for update" stage), the device may get stuck on the Apple logo. In this case, forced reset (press and hold the buttons Food + Home or Power + Volume Down depending on the model) or recovery via iTunes.

Method 3: Update iPhone via a computer (Mac or Windows)

The most reliable way to update iPhone without Wi-Fi - use iTunes (on Windows) or Finder (on Mac With macOS Catalina and newer). This method is suitable even if you have a slow mobile internet connection, since the firmware is downloaded to your computer and transferred to the phone via cable.

Step-by-step instructions:

1. Connect iPhone to the computer via the original cable Lightning/USB-C.

   • On Windows: iTunes (download the latest version from the website Apple, if not installed).

Choose yours iPhone in the program interface.

In the section Review click Refresh (Not Restore!).

Confirm the download and wait for the process to complete.

⚠️ Attention: If iTunes/Finder offers Restore instead of Refresh, this means the current firmware is corrupted. Restoring will erase all data on the device! First, try making a backup via Settings → [Your name] → iCloud → iCloud Backup.

Method 4: Use a VPN to bypass carrier restrictions

Some users have reported that connecting to VPN Allows you to bypass blocking of large file downloads over mobile data. This method doesn't always work, but it's worth a try if other options aren't available.

How does this work:

1. Install a free VPN app (for example, ProtonVPN, Windscribe or 1.1.1.1 from Cloudflare).
2. Connect to a server in your country (to minimize latency).
3. Go to Settings → General → Software Update and try to start the download.

🔹 Why does this sometimes work??: Some operators block large downloads at the DNS level or through Deep Packet Inspection (DPI). VPN Encrypts traffic, making it invisible to the provider.

🔸 Risks:

• Free VPNs may limit speed or bandwidth.
• Some VPNs block large downloads themselves.
• The ping may increase, which will lead to a connection break.

Method 5: Download the firmware in advance using third-party services

If you have access to Wi-Fi on another device (for example, at work or at a friend’s), you can download the firmware file in advance (.ipsw) and install it later. To do this:

1. Find the latest firmware for your model iPhone on the website ipsw.me (official source - website Apple, but there is no direct download link).
2. Download the file .ipsw to the computer.
3. Connect iPhone to the computer and open iTunes/Finder.
4. Clamp Shift (on Windows) or Option (on Mac) and press Refresh in the program interface.
5. Select the downloaded one .ipsw-file and confirm the installation.

⚠️ Attention: Install only official firmware From trusted sources! Files from torrents or dubious sites may contain malware or be corrupted.

FAQ: Answers to Frequently Asked Questions

Can I update my iPhone using mobile data if I have a pay-per-megabyte plan?

Technically yes, but it's extremely unprofitable. For example, an update iOS 17 weighs in at ~3 GB. At 5 rubles/MB, you'll spend ~15,000 rubles on traffic alone. It's better to find Wi-Fi or use a computer.

Why doesn't the update download after enabling the "Allow large downloads" option?

Possible reasons:

• The operator is blocking traffic at the network level (try VPN).
• The device is enabled Low data consumption mode (Settings → Cellular → Data Options).
• Apple has temporarily suspended the distribution of the update (check the status on Apple website).

Will updating via a hotspot work if Personal Hotspot is enabled on the first iPhone?

Yes, but keep in mind:

• The speed will be lower than with a direct connection to Wi-Fi.
• Some operators limit the speed in modem mode (for example, to 64 Kbps after the limit is exhausted).
• It must be enabled on both devices. Bluetooth And Wi-Fi (even if the Internet is via a cellular network).

Is it possible to roll back an iOS update if my iPhone's performance has worsened after it?
