Sometimes the system may take some time to receive configuration data from your carrier.

⚠️ Note: If the "Modem Mode" option is missing, your tariff plan may not include this feature. Contact your carrier's support team to clarify the terms of service.

After you activate the "Allow others" slider, your iPhone will begin broadcasting the network. You can change the device name and password for security purposes, preventing unauthorized access to your hotspot. It is recommended to set complex passwords containing letters and numbers.

Connecting laptops and tablets to the iPhone network

Once the phone has started broadcasting a signal, the client device must be connected correctly. In the case of laptops based on Windows or macOS The process is standard: open the list of available networks and find your smartphone's name. By default, it matches the device name unless you've changed it previously.

Enter the password you set earlier. It is important to note that security protocolThe Wi-Fi network used by iPhones is usually quite reliable, but older devices may have trouble connecting. If your laptop sees the network but won't connect, try forgetting the network in your Wi-Fi settings and signing in again.

Problems displaying modem mode

Users often wonder why the tethering option has disappeared or why a menu item is unavailable. This could be due to a carrier profile update or network module malfunctions. The first step is to check for iOS updates, as Apple regularly releases patches to fix network issues.

Another common cause is a network settings issue. In this case, resetting the network settings can help, returning all connection parameters to factory defaults. Don't worry, your personal data, photos, and contacts will be saved. will not be harmed, but saved Wi-Fi passwords will have to be re-entered.

To perform a reset, follow the path Settings → General → Transfer or reset iPhone → Reset → Reset Network SettingsAfter restarting your device, check if the desired menu item appears. If the issue persists, you may need to replace your SIM card with a newer one that supports modern communication standards.

What to do if resetting doesn't help?

If standard methods don't work, try removing the SIM card and gently cleaning the contacts with an eraser. It's also worth checking to see if a jailbreak tweak is blocking the modem. In rare cases, a full restore of the device via iTunes or Finder with a backup may help.

Wi-Fi Sharing Features on Different iPhone Models

Internet sharing functionality may vary depending on the device generation. Older models, such as iPhone 6 or 7, can run slower and run hotter when actively transferring data. Newer models with A14 series processors and above handle this task much more efficiently.

Particular attention should be paid to frequency band support. Modern iPhones operate in the 5 GHz band, which provides high speed but shorter range. Older devices can only see 2.4 GHz. Band switching occurs automatically depending on the connected client.

Owners of dual SIM devices (one physical and one eSIM) should be aware that data is shared with the SIM card selected as the default mobile data source. You can switch the data source in your mobile settings by selecting the desired number under "Mobile Data."

Personal Hotspot Security and Protection

Using networks carries risks, but even a personal hotspot requires attention to security. WPA2/WPA3 encryptionThe default encryption method reliably protects transmitted data from simple interception. However, weak passwords can negate all these security efforts.

Don't leave your tethering mode turned on all the time when you're not using it. This not only saves battery life but also reduces the risk of unauthorized connections. Attackers can use special scanners to find open or poorly secured networks in crowded areas.

If an unknown device connects to your network, change your password immediately. You can see the number of connected clients in the tethering settings. If you have any doubts, it's best to completely disable the feature and reactivate it with a new access key.

• 🔐 Use a password that is at least 10 characters long, including numbers and special characters.
• 👀 Periodically check the list of connected devices in the settings.
• 🚫 Disable "Tethering" immediately after finishing work.
• 📡 Avoid using simple passwords like "12345678" or "password".

⚠️ Note: The settings interface and layout may vary slightly depending on your iOS version. If you don't find the option you're looking for, search for it in Settings (the magnifying glass icon at the top of the screen).

Saving traffic and battery power while using the modem

Sharing Wi-Fi is a power-hungry process that quickly drains your battery. To extend battery life, it's recommended to reduce your smartphone's screen brightness or turn it off completely, leaving it connected to a charger. It's also a good idea to disable background app refresh while sharing.

Monitoring your traffic is another important aspect, especially if you don't have an unlimited plan. You can reset your statistics in your mobile network settings before starting a session to see exactly how many megabytes you've used. Some carriers offer separate gigabyte packages specifically for tethering.

To save battery, you can turn off 5G if high speed is not required and leave only 4G. Switch in the menu Settings → Cellular → Data Options → Voice & Data This will help save energy, as searching for a 5G network uses more resources.

How do I find out how much traffic was spent on distribution?

The default iOS settings don't have a separate counter specifically for tethering, but you can track your overall usage. Go to Settings → Cellular and scroll down to the bottom of the list. The total amount of data transferred will be displayed there. For precise monitoring, it's best to use your carrier's apps, which often provide detailed breakdowns by traffic type.

Why does my iPhone get hot when tethering is enabled?

This is a normal physical phenomenon. Communication modules are working at the limit of their capabilities, converting radio signals. If the temperature becomes excessive, the phone may temporarily disable the modem to protect the components. Remove the case and place the device on a cool surface.

Is it possible to share Wi-Fi with an iPhone with Activation Lock?

No, if your device is in Activation Mode or has an iCloud Lock, your phone's features, including Personal Hotspot, will not be available until you enter the correct Apple ID and password.
