Many users face a situation where they need to update the operating system on iPhone 7 Plus, but there's no access to a stable Wi-Fi network. This is a common problem, especially given that the iOS firmware file can be several gigabytes in size, and mobile data is often unstable or limited. However, there are proven methods to bypass this limitation and successfully complete the installation of the new software version.
In this article, we'll cover all possible options in detail, including using another device's mobile data, updating via a computer, and even specific settings that allow you to use a cellular network to download system files. It is important to understand, that each method has its own characteristics and requirements for preparing the gadget.
Before proceeding, make sure your device is at least 50% charged or connected to a power source. Interrupting the update process due to low battery can cause serious system errors. We'll cover how to safely perform the procedure using only the resources you have on hand.
Using mobile internet for updating
Starting with certain versions of iOS, Apple has introduced the ability to download system updates directly through the carrier's cellular network. However, for iPhone 7 Plus This functionality may be limited by available memory or firmware version. If your carrier supports this feature and you have an unlimited data plan, you can try updating directly.
To activate this option, you need to go to the device settings. Find the section Settings → Cellular and scroll down to "Data Options." There may be a toggle here to allow cellular data for system updates. If there's no such option, your data plan or current iOS version doesn't support direct downloads of large amounts of data over 4G/LTE.
⚠️ Please note: Downloading a 2-3 GB firmware file over a mobile network can quickly deplete your data plan. Make sure you have an unlimited data plan or are prepared to incur additional charges.
An alternative option is to create a hotspot. You can share the internet from another smartphone with unlimited Wi-Fi or sufficient data, and connect iPhone 7 Plus to this network. In this case, the phone will "think" it's connected to a regular wireless network and will allow the update to begin downloading.
- 📱 Enable tethering on the donor device with an active internet connection.
- 🔗 Connect your iPhone 7 Plus to the created Wi-Fi network.
- ⚙️ Go to
Settings → General → Software Update. - ⬇️ Click "Download and Install" if the system detects a new version.
Updating via a computer with iTunes
The most reliable and classic way to update iPhone 7 Plus Without Wi-Fi on the phone itself, you can use a personal computer. To do this, you'll need a PC running Windows or Mac, a Lightning cable, and iTunes installed (or Finder on macOS Catalina or later).
The process begins by connecting your device to your computer. Once the computer recognizes the phone, open iTunes and click the device icon in the top bar. In the "Summary" section, you'll see the "Update" button. Clicking it will begin the process of checking for a new version of iOS and downloading it directly to your computer, then to your phone.
☑️ Preparing for the update via PC
The main advantage of this method is the connection stability. The computer takes over the download of the heavy firmware file using its internet connection (which can be wired or Wi-Fi) and transfers the data to the phone via a cable. This eliminates the risk of download interruptions due to an unstable cellular signal.
⚠️ Important: Do not disconnect the cable or turn off your computer while updating via iTunes. Interrupting the data transfer may require you to restore your device in DFU mode.
If the automatic update does not start, you can manually download the firmware file (.ipsw) from the official Apple website corresponding to your model and install it by holding down the key Option (on Mac) or Shift (on Windows) when you click the Update button in iTunes.

For this method to work, both devices must be nearby, unlocked, and have Bluetooth enabled. The device distributing the update must be running the latest version of iOS. When you try to update your phone, the system may prompt you to use the internet connection of a nearby iPhone.
Requirements for updating from another iPhone
Both devices must be unlocked and within close proximity (up to 10 meters). Bluetooth and Wi-Fi must be enabled on both devices. The donor device must have a stable internet connection (mobile or Wi-Fi).
This method is particularly convenient because it doesn't require entering Wi-Fi passwords or complex access point settings. The system will automatically find an available device and offer to use its connection. The data transfer speed will be high enough to smoothly load system files.
- 🔍 Make sure Bluetooth is enabled on both devices.
- 📡 Bring the devices closer to each other than 1 meter.
- 🔄 The donor device may ask for permission to use the internet.

Comparison table of update methods
To help you choose the right option, we've prepared a comparison chart. It will help you assess the risks and requirements of each method based on your current situation and available resources.
| Method | Required equipment | Traffic consumption | Stability |
|---|---|---|---|
| Mobile Internet | iPhone 7 Plus, SIM card | High (2-3 GB) | Low/Medium |
| Access point | Second smartphone, cable | Depends on the donor | Average |
| Computer (iTunes) | PC/Mac, Lightning cable | PC traffic | High |
| Another iPhone | iOS device nearby | Donor traffic | High |
As the table shows, using a computer remains the "gold standard" for reliability. However, if a PC is not available, updating from another iPhone is an excellent alternative. Directly using mobile data on the device itself should only be used as a last resort.
Possible errors and solutions
When updating without Wi-Fi, users often encounter various system errors. The most common is a message stating that the update cannot be verified due to a lack of internet connection. This can occur even with an active connection, if Apple servers are temporarily unavailable or the connection is unstable.
