You find yourself in a situation where you urgently need to share the Internet with someone else. iPhone, but don't have a router handy? Or want to save on mobile data by using your main device as a hotspot? Transfer Wi-Fi from phone to phone between devices Apple This is possible in several ways, from the standard modem mode to hidden functions iOSIn this article, we'll cover all the working methods, their limitations, and configuration nuances for different versions. iPhone (from iPhone 8 to iPhone 15 Pro Max).
It is important to understand: Apple intentionally limits some internet tethering features due to carrier policies. For example, not all plans support modem mode, and in some countries, this option is blocked at the firmware level. We'll explain how to bypass common errors, such as when the second iPhone Doesn't see the network or connects, but the internet isn't working. You'll also learn how to share the internet without wasting battery power and why it is sometimes better to use Bluetooth instead of Wi-Fi.
1. Tethering via Wi-Fi: The standard way
The most common method is to turn it on on the main iPhone function Modem mode and connect to it from a second device as a regular access point. This method works on all models starting from iPhone 5, but there are important nuances:
- 📶 Transfer speed depends on the generation of the modem in your iPhone: 4G (LTE) or 5G. For example, iPhone 12 and newer ones are supported 5G in modem mode, but the operator may limit the speed.
- 🔋 Battery consumption increases by 20–40% — the device simultaneously maintains a connection to the network and distributes Wi-Fi.
- 🔒 Security: The network is protected by a password by default, but it can be changed in the settings.
To activate modem mode:
- Open
Settings → Tethering(orSettings → Cellular → Personal Hotspoton older versions iOS). - Move the slider
Allow othersto the right. - Remember or change your password in the section
Wi-Fi password. - On the second iPhone go to
Settings → Wi-Fiand select the network with the name of your main device (for example,iPhone (YourName)).
Is mobile internet enabled on your primary iPhone?
Is the signal level sufficient (at least 2-3 divisions)?
Is Airplane Mode Active?
Does the tariff support modem mode (check with your operator)?
If the second one iPhone doesn't connect, try:
- 🔄 Restart both devices.
- 📱 On the main iPhone turn it off and on again
Modem mode. - 🔐 Make sure you entered your password correctly (case-sensitive!).
2. Transferring Internet via Bluetooth: saving battery power
A lesser known but more economical method is to distribute the Internet over BluetoothIt consumes 15-25% less battery than Wi-Fi, and is suitable if you need stable data transfer without high speed (for example, for instant messaging or email). Cons: the speed is limited to ~1–2 Mbps (versus 10–50 Mbps for Wi-Fi).
How to set up:
- On the main iPhone turn on
Modem mode(as in the previous section) and activate Bluetooth VControl centerorSettings → Bluetooth. - On the second iPhone also include Bluetooth and wait until the name of the main device appears in the list.
- Connect to it - you may need to confirm the code on both phones.
- Return to
Settings → Cellular → Personal Hotspoton the second iPhone and select the primary device in the sectionPersonal hotspot.
Why is Bluetooth slower than Wi-Fi?
Speed Bluetooth limited by the protocol: even in version 5.0, the actual throughput rarely exceeds 2–3 Mbps. For comparison, Wi-Fi in modem mode on iPhone delivers up to 50 Mbps (on iPhone 13/14/15 With 5G).
When to choose Bluetooth:
- 🔋 You need to save battery power (for example, when traveling without a power outlet).
- 📶 The mobile network signal is weak - Bluetooth Maintains a more stable connection at a distance of up to 10 meters.
- 🔒 You are transmitting confidential data — Bluetooth- the connection is more difficult to intercept.
⚠️ Attention: Some operators (eg. Beeline or Tele2 in Russia) they can block internet distribution through Bluetooth On certain plans. If the connection isn't working, check your plan's terms in your personal account.
3. Internet sharing via USB: maximum stability
The most reliable, but least convenient way is to connect via USB-cable. It guarantees stable speed (up to 40–60 Mbps) and minimal battery consumption of the main iPhone, since power is supplied by the connected device. However, this will require:
- 🔌 Lightning-cable (for iPhone to 14th series) or USB-C (For iPhone 15).
- 📱 Second iPhone with support
USB debugging(the function appeared in iOS 13 and newer). - 🔒 Trusted connection between devices (needs to be confirmed on both phones).
Step-by-step instructions:
- Connect both iPhone cable. A prompt will appear on the main device.
Trust this computer?- clickTrust. - On the main iPhone turn on
Modem mode(Settings → Tethering). - On the second device, go to
Settings → Cellular → Personal Hotspotand select connection via USB.
Important: When connecting via USB second iPhone It will charge from the first device if it's plugged into a power outlet. This is the only way to share the internet without draining the main device's battery.
| Distribution method | Speed | Battery consumption | Stability | Convenience |
|---|---|---|---|---|
| Wi-Fi | ⭐⭐⭐⭐⭐ (up to 50 Mbps) | ⭐ (high) | ⭐⭐⭐ (depending on signal) | ⭐⭐⭐⭐ (ease of connection) |
| Bluetooth | ⭐ (1–2 Mbps) | ⭐⭐⭐ (low) | ⭐⭐⭐⭐ (stable at a distance) | ⭐⭐ (requires a pair of devices) |
| USB | ⭐⭐⭐⭐ (up to 60 Mbps) | ⭐⭐⭐⭐ (minimal) | ⭐⭐⭐⭐⭐ (no breaks) | ⭐ (cable required) |
4. Operator restrictions: why distribution may not work
Even if you set it up correctly modem modeInternet access may not be available due to mobile operator policies. Here are typical restrictions:
- 🚫 Modem mode is blocked: on some tariffs (especially budget ones), operators disable this function. For example, MTS in the "Smart" tariff distribution Wi-Fi available only after paying for an additional option.
- 📉 Speed Limit: after high-speed traffic is exhausted, the speed in modem mode may drop to 64–128 kbps (practically unusable).
- 🔄 Traffic limits: Some operators count traffic in modem mode separately from the main package. For example, Yota distribution Wi-Fi comes from a special "modem package".
How to check if your plan supports tethering:
- Call the operator (numbers: MTS —
0890, Beeline —0611, Megaphone —0500, Tele2 —611). - Send a USSD request:
(For MTS) or*111#
(For Beeline).*105# - Check your personal account on the operator's website in the "My Services" or "Tariff" section.
⚠️ Attention: If you use eSIM, make sure that modem mode is enabled for this virtual SIM card. Some operators (for example, Tinkoff Mobile) by default block distribution on eSIM.

5. Troubleshooting: Why iPhone Can't See Network or Why Internet Doesn't Work
If you have enabled Modem mode, but the second iPhone If you cannot connect or connect without internet access, please check the following:
- 🔍 APN settings: Incorrect access point name (APN) settings may be blocking data sharing. Check with your carrier or reset your settings.
Settings → Cellular → Data Options → Reset. - 📵 Airplane mode: even if Wi-Fi It is turned on separately, the modem mode does not work in it.
- 🔄 IP address conflict: if both iPhone connected to the same network (for example, home Wi-Fi), turn it off before distributing.
- 🔋 Low battery: if on the main one iPhone less than 20% charge, iOS can automatically disable modem mode.
Common mistakes and their solutions:
| Error | Cause | Solution |
|---|---|---|
Failed to activate modem mode |
The operator blocks the function | Call support or change your tariff |
Connected, but no internet |
Incorrect APN settings | Reset network settings (Settings → General → Transfer or reset → Reset → Reset network settings) |
iPhone not showing up in Wi-Fi list |
Modem mode is not enabled or has failed. iOS | Reboot both devices and enable the mode again. |
The connection is lost after 1-2 minutes |
Energy Saver turns off Wi-Fi | Disable Low power mode (Settings → Battery) |
6. Alternative methods: when tethering is unavailable
If the operator has blocked Internet distribution or your iPhone does not support modem mode (for example, on iPhone 4/4S), you can use workarounds:
- 🌐 Hotspot applications: programs like PdaNet+ or MyWi emulate modem mode through USB or Bluetooth, bypassing operator restrictions. Cons: Requires jailbreak on newer versions iOS.
- 🔗 VPN bypass: some VPN- services (for example, 1.1.1.1 from Cloudflare) allow you to distribute the Internet through Wi-Fi, even if the operator blocks the standard modem mode.
- 📡 External modem: connect to iPhone 4G/5G router (For example, Huawei E5577) and share internet from it. This is useful for trips where a stable network is needed for multiple devices.
Jailbreak Warning: Installing unofficial apps for internet sharing requires hacking iOS (jailbreak). This violates the warranty terms. Apple and can lead to:
- 🛡️ Blocking updates iOS.
- 🔓 Security vulnerabilities (risk of viruses).
- 📱 Unstable operation of the device (app crashes).
How does VPN bypass work?
Some VPN-applications create a virtual tunnel through which traffic from the second iPhone It passes through as normal data from the main device. The operator sees only encrypted traffic and cannot block distribution. However, the speed will be lower due to the encryption.
7. Optimize traffic and battery consumption
Internet distribution with iPhone can quickly drain both your mobile data and battery. To avoid this:
- 📊 Monitor traffic: V
Settings → Cellularturn on the optionStatisticsto see how much data the second one is using iPhone. - ⚡ Use economy mode:
Settings → Battery → Low Power Mode(but remember that it may turn off the modem mode when the battery is low).
- 🔌 Connect the power: if you distribute Wi-Fi long, use Power Bank - this will prevent sudden shutdown.
- 🛑 Limit background activity: on the second iPhone Turn off automatic app updates (
Settings → App Store → Auto-update).
How much traffic does distribution use?
Depends on the actions on the second device:
- 📧 Checking mail/messengers: ~50–100 MB/hour.
- 🎵 Streaming Music (Apple Music, Spotify): ~70–150 MB/hour.
- 🎬 Video in
720p(YouTube, TikTok): ~500–700 MB/hour. - 🎮 Online games: ~100–300 MB/hour (depending on the game).
FAQ: Frequently asked questions about sharing Wi-Fi from iPhone to iPhone
Is it possible to share internet from iPhone to iPhone without using tethering?
