When a fixed router is unavailable and mobile internet is essential, a smartphone can serve as a full-fledged hotspot. Apple device owners often wonder how to share Wi-Fi from iPhone to iPhone to ensure a stable connection for the second device. This feature, known as Personal Hotspot, is built into iOS and doesn't require any third-party apps.
The activation process takes only a few seconds, but has a number of nuances depending on the operating system version and operator settings. Modem mode Allows you to turn your smartphone into a wireless router that other devices can connect to. It's important to note that data transfer speeds will depend on your cellular network coverage and data plan.
Before setting up, make sure cellular data is enabled on the donor device. If the internet isn't working on the phone itself, you won't be able to share it with other devices. It's also worth checking your mobile carrier's balance and whether tethering is enabled.
Checking your tariff plan and operator settings
The first step before sharing Wi-Fi from your iPhone is to make sure your carrier supports this feature. Some data plans may block Wi-Fi sharing or charge additional fees. Carriers often monitor TTL (Time To Live) packets to determine whether the connection is being used for distribution.
If this option isn't enabled on your provider's end, the "Modem Mode" menu may be hidden or not function properly. In this case, please contact customer support or check your subscriber account. Sometimes, simply updating your network settings is enough for your provider profile to display correctly in the system.
⚠️ Attention: Uncontrolled internet sharing can quickly deplete your data plan. Make sure connected devices don't start downloading large files or updating their systems without your permission.
To update your network settings, go to Settings → General → AboutIf an operator profile update is available, a notification will appear on the screen. This often resolves issues with the sharing menu item disappearing.
Activating Personal Hotspot on iPhone
After checking your plan, you can proceed to setting up the hotspot. The iOS interface is the same for most models, whether iPhone 13, iPhone 14 or older versions. To get started, go to the settings menu and find the appropriate section.
Tap "Tethering" in the main menu or under "Cellular." Here, you'll need to toggle the "Allow Others to Use" slider to the on position. Once enabled, the system will generate a password for the connection, which you can change to something easier to remember.
- 📱 Open the Settings app from your home screen.
- 📡 Go to the "Cellular" section or find the "Tethering" option.
- 🔓 Turn on the "Allow others" switch.
- 🔑 Remember or change the Wi-Fi password displayed on the screen.
If you don't see this option in the menu, it may be hidden. Try searching for "modem" in the settings. Also, make sure your device has cellular data enabled and there are no parental controls blocking this feature.
☑️ Check before switching on
Connecting a second iPhone to a hotspot
Once the hotspot is activated, a second iPhone (or any other device) can connect to it like a regular Wi-Fi network. The network name defaults to the name of the donor device, which is specified in the section General → About this device → Name.
On the receiving device, open the list of available Wi-Fi networks. Find the name of your primary iPhone in the list and tap it. The system will ask for the password you saw on the sending device's screen or set earlier.
After entering the password and successfully authorizing, a chain icon or two linked links will appear at the top of the receiving iPhone's screen, indicating an active tethering connection. From this point on, all traffic will flow through the SIM card of the first device.
>Random character set
| Parameter | Default value | Recommendation |
|---|---|---|
| Network name | iPhone (or owner's name) | Unique name for identification |
| Security | WPA2/WPA3 Personal | Leave unchanged |
| Password | Replace with something complex but memorable | |
| Range | 2.4 GHz / 5 GHz | Depends on the iPhone model |
It is important to note that when connected via Wi-Fi, power consumption on both devices increases. Access point creates a constant radio field, which requires significant processor and modem resources.
Why can't I see the Wi-Fi network?
If you don't see your iPhone's network in the list of available networks, make sure Wi-Fi is also enabled on the receiving device. Sometimes, rebooting the wireless module or temporarily disabling the "Private Wi-Fi Address" feature in the receiving device's network settings can help.
Use Family Sharing to quickly connect
For owners of multiple Apple devices, the ecosystem offers a simplified connection method that eliminates the need to enter a password each time. Family Sharing allows for automatic authorization of family members' devices. To do this, both iPhones must be linked to the same family group.
When tethering is enabled on one device, a system notification appears on other devices in the family indicating the connection is possible. You don't need to search for the network in the list or enter complex character combinations. Simply click "Connect" in the pop-up window.
This method is not only convenient but also secure, as the password is not transmitted in clear text or stored explicitly in the device's memory. The authorization mechanism uses secure Apple ID keys.
- 👨👩👧👦 Set up Family Sharing in iCloud on both devices.
- 📲 Turn on Personal Hotspot on your primary iPhone.
- 🔔 Wait for the notification on the second iPhone.
- ✅ Confirm the connection without entering a password.
Please note that for this feature to work, both devices must be signed in to iCloud, and Family Sharing must be correctly configured by the group organizer.
Alternative methods of internet transmission
While Wi-Fi is the most popular sharing method, it's not always optimal. In some cases, a wired connection or Bluetooth makes more sense. A wired connection (USB) provides the greatest stability and speed, and also charges the receiving device.
To connect via a Lightning or USB-C cable, connect both iPhones (or the iPhone and the computer) with a wire. The receiving device may display a "Trust this computer?" prompt, which you must answer affirmatively. Data transfer speeds in this mode are often higher than wireless.
⚠️ Attention: When using a USB cable for internet sharing, make sure the cable is in good condition and supports data transfer, not just charging. Cheap cables without proper contacts will not transmit an internet signal.
A Bluetooth modem is an option for those who prioritize maximum energy efficiency over speed. Bluetooth connection speeds are significantly slower than Wi-Fi or USB, and are primarily suitable for messaging and navigation.
Troubleshooting connection issues and errors
Even with proper setup, users may encounter difficulties. Often, the problem stems from a software glitch or a network settings conflict. If your iPhone isn't sharing Wi-Fi, the first thing you should try is restarting both devices—this resolves most temporary iOS glitches.
Another common cause is resetting network settings. This will reset all network settings to factory defaults, delete saved Wi-Fi passwords and Bluetooth settings, but often restores tethering functionality. Here's how to reset: Settings → General → Transfer or reset iPhone → Reset → Reset Network Settings.
It's also worth paying attention to the iOS version. If one device is running a very old version of the system and the other is running the latest beta version, security protocol compatibility issues may arise.
- 🔄 Restart both smartphones.
- 📶 Turn Airplane Mode off and on for 10 seconds.
- 🗑️ Reset network settings in the main settings menu.
- 💾 Update iOS to the latest available version.
If nothing helps, the problem may be hardware-related or related to a blocking by the operator that cannot be bypassed using software.
Impact of distribution on battery and safety
Sharing the internet is a resource-intensive process. The Wi-Fi module operates in constant transmission mode, and the processor processes data packets for multiple devices. This leads to rapid battery drain and heating of the donor device.
To minimize damage, it's recommended to keep your iPhone connected to a charger while sharing. However, avoid overheating, as the system may forcefully disable tethering or reduce screen brightness if the temperature reaches a critical level.
Security issues also shouldn't be ignored. An open Wi-Fi network allows anyone nearby to try to connect to your traffic. Be sure to use a strong password and WPA2/WPA3 encryption.
Furthermore, when connecting to other devices via your IP address, it's theoretically possible to access local resources if the proper isolation level isn't configured. iOS has good isolation, but you shouldn't let your guard down.
Why is the green bar at the top of the screen lit up?
A green bar or dot in the Dynamic Island area indicates that the microphone or camera is currently in use, or that Personal Hotspot is active. A green light next to the cellular icon indicates that tethering is active and transmitting data.
Is it possible to share Wi-Fi if the iPhone doesn't have a SIM card?
No, a SIM card with an active plan is required to share mobile data. However, if an iPhone has previously connected to a Wi-Fi network and saved the password, it can theoretically rebroadcast the signal, but this isn't supported by standard iOS features. The iPhone can only act as a bridge between the cellular network and Wi-Fi clients.
How many devices can be connected at the same time?
The number of devices that can be connected depends on the iPhone model and iOS version. iOS typically supports up to five simultaneous Wi-Fi connections. When connecting via USB or Bluetooth, the limits may vary, but typically support multiple devices.
What should I do if the connected device says "No network access"?
This means the connection is established, but the internet connection isn't being shared. Check if the donor iPhone has internet access. Open Safari and try loading a page. Also, check to see if your data plan has run out or if your carrier is blocking the connection.
