The situation when the device runs out of space to download updates, and there is no computer to connect the cable to, is familiar to many users of the ecosystem AppleIn such cases, the only way out is to use an alternative internet source, which may be mobile traffic another smartphone. This solution avoids the complicated process of restoring via iTunes or Finder, requiring only a stable connection.
However, the process of updating the operating system via an access point has its own technical nuances that must be taken into account for the successful completion of the operation. Data transfer rate Signal stability and reliability are critical here, as interrupting the firmware download can lead to errors. Below, we'll detail the steps to help you safely install the new version of iOS.
It's important to understand that the amount of data downloaded can be significant, especially when upgrading between major system versions. Therefore, before beginning the process, make sure your SIM card plan allows for large amounts of data or that you are in a strong signal area. 4G/5G.

You should also free up some space on your device if automatic downloads are not possible due to insufficient space. The system may temporarily require up to 10-15 GB of free memory to unpack and install files, even if the final update size is smaller. Delete unnecessary apps or photos to ensure the process starts smoothly.
Check your device model, as not all gadgets support the latest versions of the operating system. If your iPhone Since this device is an older model, update servers may only offer the latest available software version. This is normal and not a configuration error.

- 📡 Make sure that mobile data is enabled on the distributing phone.
- 🔋 Check your battery level, as using Wi-Fi will drain your battery significantly faster.
After activating the mode on the second device, go to Wi-Fi settings on your iPhone and select the network created by the partner phone. Enter the previously set password to connect. A successful connection will be confirmed by the corresponding icon appearing in the status bar.
It's worth noting that the update speed will directly depend on the quality of the cellular network signal in your location. If the indicator shows EDGE or weak 3GThe process may take several hours or be interrupted. In such cases, it's best to move to an area with stronger signal.

After the file downloads, the system will ask for installation confirmation, after which the phone will reboot.
☑️ Pre-Start Checklist
Common mistakes and how to solve them
Even if you follow all the instructions, technical issues may still occur. One common problem is a message stating that the app cannot check for updates. This is often due to temporary server issues or connection instability.
If the download freezes at any point, try turning airplane mode on and off on both devices. This will help reconnect to the cell tower and update. IP address, which often solves the freezing problem.
| Error | Probable cause | Solution method |
|---|---|---|
| Failed to check for updates | DNS or server issues | Rebooting the router or the phone that distributes |
| Not enough space | Low free memory | Deleting photos, videos, and apps |
| Connection error | Weak network signal | Change location or reconnect |
| Incorrect password | Wi-Fi key entry error | Forget the network and re-enter the password |

Features of updating across different platforms
There is a difference in how exactly the Internet is distributed: from a device based on Android or from another iPhoneWhen using an Android smartphone as a hotspot, manual frequency band adjustments are sometimes required. Some older iPhone models may not detect a network if it's broadcasting on the 5 GHz frequency.
In Android's hotspot settings, it's recommended to select the 2.4 GHz band for maximum compatibility. This will ensure a more stable, though not the fastest, connection, which is more important for long-term system file downloads. Channel stability in this case, priority is given to peak speed.
Why is it better to use 2.4 GHz?
The 2.4 GHz band has a longer range and better penetration through obstacles, which is critical if the transmitting phone isn't located near the device being upgraded. Furthermore, most older iPhone models are guaranteed to work with this standard.
If you're sharing from another iPhone, the process is as transparent as possible thanks to the ecosystem. Devices automatically detect each other if Bluetooth and iCloud are enabled. However, data usage should still be monitored to avoid exceeding your data plan's limits.
