How to connect to Wi-Fi from another smartphone: all methods + troubleshooting

Are you in a situation where you urgently need to get online, but all you have is your smartphone, no SIM card, or no data? Or do you want to share your mobile data with a friend who doesn't have internet access? Connect to Wi-Fi of another smartphone It can be done in minutes—if you know the right settings and nuances. In this article, we'll cover all the working methods: from the standard access point to hidden functions. Android And iOSWe'll also tell you how to avoid common errors like "Unable to connect to the network" or "No internet access."

It is important to understand that when you connect to smartphone Wi-Fi, you actually use it as routerThis means that traffic will be consumed from the SIM card of the device sharing the internet. Connection speed depends on the quality of the mobile network (3G/4G/5G) and the number of connected devices. If you have an unlimited data plan, this won't be a problem, but if you have limited data, you should monitor your data usage.

We have tested all methods on the latest versions. Android 14 And iOS 17, but most of the instructions will also work for older devices (starting with Android 8.0 And iOS 12). If your smartphone runs on a different firmware (for example, MIUI, One UI or ColorOS), the menu paths may differ slightly - look for similar sections.

Method 1: Wi-Fi hotspot (the easiest option)

This is a standard method that works on all modern smartphones. The idea is simple: one device creates Wi-Fi network, and the second one connects to it. The main advantages are high data transfer speeds and the ability to connect multiple devices at once (usually up to 10).

On Android The path to the settings may differ depending on the shell, but the general algorithm is as follows:

  1. Open Settings → Network & Internet → Hotspot & Tethering (or Mobile hotspot).
  2. Tap on Mobile hotspot (sometimes called Modem mode).
  3. Turn on the slider and adjust the network settings if necessary:
    • 🔄 Network name (SSID) - come up with a unique name (for example, iPhone_X_Sergey).
    • 🔒 Password — minimum 8 characters, preferably with numbers and letters.
    • 📶 Range — choose 2.4 GHz for better compatibility or 5 GHz for speed (if supported).
  • Connect the second smartphone to the created network as to a regular Wi-Fi.

    • On iPhone the process is even simpler:

    1. Go to Settings → Tethering (or Cellular → Personal Hotspot).
    2. Activate the slider Allow others.
    3. The default password can be found in the same menu or changed (at least 8 characters).
    4. On the second device, select the network with the name of your iPhone (For example, iPhone (Sergey)) and enter the password.

      5. Make sure the mobile internet is enabled on the sharing smartphone|Check the remaining data on the SIM card|Disable the VPN on both devices|Restart the smartphones if the connection is not established

      -->

      If the access point does not turn on, check:

      • 📱 Telecom operator - some tariffs block Internet distribution (especially on MTS, Beeline or Tele2 old tariffs).
      • 🔧 Energy settings - on Android In power saving mode, the access point can turn off automatically.
      • 🔄 Software updates - on older versions iOS (below 13) there may be bugs with distribution.

    2. Method: Connecting via Bluetooth (saves battery)

    If Wi-Fi distribution drains your battery quickly or you are in a place with interference (for example, in the subway), you can use Bluetooth modemThis method is slower (up to 3 Mbps), but uses significantly less power. It's suitable for messaging, checking email, or leisurely surfing.

    Instructions for Android:

    1. Turn on Bluetooth on both smartphones.
    2. On the distributing device, go to Settings → Network & Internet → Hotspot & Tethering → Bluetooth Tethering.
    3. Activate the slider and confirm pairing on the second phone.
    4. On the receiving smartphone in the settings Bluetooth Find the distributing device and connect to it as a modem.

    On iPhone the algorithm is similar:

    1. Turn on Bluetooth V Control center.
    2. Go to Settings → Tethering and activate the option.
    3. On the second iPhone or Android find the first device in the list Bluetooth and connect.

    Please note:

    • 🔋 Energy consumption — A Bluetooth modem consumes battery power 2–3 times slower than Wi-Fi.
    • 📱 Compatibility - some older smartphones (for example, Samsung Galaxy S7 or iPhone 6) may not support this mode.
    • 🛡️ Security — the connection is encrypted, but the range is limited to 10 meters.
    Why is Bluetooth modem slower than Wi-Fi?

    Bluetooth data transfer speeds (even in version 5.0) are limited to 3 Mbps, while Wi-Fi in 5 GHz mode can deliver up to 1 Gbps. This is due to the technical specifics of the protocols: Bluetooth is optimized for low-power devices (headphones, fitness trackers), while Wi-Fi is optimized for transmitting large amounts of data.

    3. Method: USB modem (maximum stability)

    If you have USB cable (better than the original), this method will provide the most stable connection without speed loss. Suitable for Android-smartphones and iPhone (but with some nuances). The main advantage is that there's no risk of sudden disconnection, as with wireless methods.

    For Android:

    1. Connect the smartphones with a cable (may be required OTG adapter for a new device with USB-C).
    2. On the sending phone, go to Settings → Network & Internet → Hotspot & Tethering → USB Tethering.
    3. Activate the slider. The internet should appear automatically on the second device.

    For iPhone:

    • 🍏 Apple's restriction - officially iPhone does not support USB modem for other smartphones, only for PC (Mac or Windows).
    • 🔌 Workaround - you can try to connect iPhone To Android through USB-C/Lightning-cable and turn on Modem mode, but this does not guarantee stable operation.

    Important: When connected via USB Android- the smartphone can start charging from a second device if it supports it OTG with power. This is normal and does not harm the battery.

    Connection method Speed Battery consumption Difficulty of setup Suitable for
    Wi-Fi (hotspot) ⚡ High (up to 1 Gbps) 🔋 Average (3–5% per hour) ⭐ It's very simple Any devices
    Bluetooth 🐢 Low (up to 3 Mbps) 🔋 Low (1–2% per hour) ⭐⭐ Simply Messages, mail
    USB ⚡ High (depending on cable) 🔋 Low (charging) ⭐⭐⭐ Average Android → Android/PC

    4. Method: Using QR code (quick connection)

    If you frequently share your internet connection with the same devices, you can simplify the process by using QR codeThis method works on Android 10+ and some firmware (for example, MIUI 12 or One UI 3.0).

    How to set up:

    1. Turn on the hotspot on the sharing smartphone (see first method).
    2. Tap on the icon QR code next to the network name (or find the option in the access point menu).
    3. On the second smartphone, open the camera and point it at the QR code. The system will automatically prompt you to connect.

    Advantages of the method:

    • ⚡ Instant connection - no need to enter the password manually.
    • 🔒 Security — The QR code contains encrypted network data.
    • 📱 Versatility — works even if the keyboard is disabled on the second device.

    5. Troubleshooting: "Unable to connect to the network"

    Even with the correct settings, errors can still occur. Here are the most common ones and how to fix them:

    Problem 1: "Connected, no internet access"

    • 🔄 Restart both devices — sometimes a simple reboot helps.
    • 📶 Check your mobile network — the signal on the transmitting smartphone may have disappeared (switch to 4G/3G manually).
    • 🔧 Reset network settings on the receiving device: Settings → System → Reset → Reset Wi-Fi, mobile networks, and Bluetooth.

    Problem 2: "Incorrect password" (even though you are sure it is correct)

    • 🔠 Check your keyboard layout — the password is case sensitive.
    • 🔄 Generate a new password - sometimes changing symbols helps (for example, replacing O on 0).
    • 📱 Update the firmware - on older versions Android (below 9.0) there are bugs with password encryption.

    Problem 3: The access point turns off by itself

    • 🔋 Turn off battery saving for the application Settings or Modem mode.
    • ⏱️ Increase the timeout - in some firmware (for example, Xiaomi) the access point turns off after 5-10 minutes of inactivity. Look for the setting Turn off when idle.
    • 📴 Check your operator settings - some tariffs (for example, MegaFon "Everything for Communication") block the distribution.
    ⚠️ Attention: On some mobile operator plans, internet tethering may be charged separately or blocked. For example, MTS The "Smart" tariff limited upload speed to 64 kbps until 2023. Check the terms in your personal account or with your operator.

    6. Alternative methods: if nothing works

    If standard methods don't work, try these options:

    Method 1: Internet Sharing Apps

    IN Google Play And App Store There are utilities that simplify access point setup. Popular ones include:

    • 📱 PdaNet+ - works even on devices blocked by the operator (requires root on Android).
    • 🌐 ClockworkMod Tether - an alternative to the standard modem (supports USB/Bluetooth/Wi-Fi).
    • 🍏 MyWi - a paid application for iPhone with advanced settings (requires jailbreak).

    Method 2: USB-Ethernet Mode (Advanced)

    If you have ROOT rights on Android, you can set up distribution through USB-ethernet (required) Linux(A computer or special software). The speed will be higher than Wi-Fi, but the method is complex and risky.

    adb shell

    su
    

    setprop sys.usb.config rndis,adb

    Method 3: Hot Spot via Windows/Mac

    If you have a laptop at hand:

    1. Connect the sharing smartphone to the PC via USB and turn it on USB modem.
    2. On your PC, enable Wi-Fi sharing via Command line (Windows) or General access (Mac).
    3. Connect the second smartphone to the laptop's network.
    ⚠️ Attention: Usage rootUsing permissions or jailbreaking to share the internet may void your device's warranty and lead to unstable operation. Back up your data before experimenting.

    7. Security: How to protect your access point

    By sharing Wi-Fi from your smartphone, you risk allowing others to connect to your network. Here's how to avoid this:

    Basic measures:

    • 🔒 Complex password - use a combination of 12+ characters (eg. k7#pL9!mQ2$vR5).
    • 🔄 Change password — update it once a month if you often share the Internet in public places.
    • 📵 Disabling the access point - Turn it off when not in use.

    Additional protection:

    • 🛡️ Hiding the network (SSID) - disable the option in the access point settings Broadcast network nameYou'll have to connect manually, but strangers won't see your Wi-Fi.
    • 📱 Device restrictions - some firmware (for example, EMUI on Huawei) allow you to create a "white list" of MAC addresses.
    • 🔧 VPN on the distributing device - If you connect to public networks, use ProtonVPN or Windscribe to encrypt traffic.

    What to do if someone connects to your network without permission?

    1. Immediately turn off the access point.
    2. Check the list of connected devices in the modem settings (on Android This Connected devices).
    3. Change password And network name.
    4. If you suspect a malicious connection, check your smartphone for viruses (Malwarebytes or Kaspersky).

    FAQ: Frequently Asked Questions

    ❓ Is it possible to connect to a smartphone's Wi-Fi without a password?

    Technically yes, but only if encryption is disabled on the distributing device (option No protection in the access point settings). This is extremely unsafe - everyone within range will be able to connect to your network. iPhone It is impossible to disable the password.

    ❓ Why does it happen when connecting to an access point with iPhone no internet?

    A common issue is related to your carrier's settings. Check:

    1. Is it included? Modem mode V Settings → Cellular.
    2. Is the option activated? Cellular data for distribution (sometimes a separate setting in the operator profile is required).
    3. Are there any tariff restrictions (for example, Beeline (in the "Everything is simple" tariff, it blocks distribution).

    If nothing helps, try resetting your network settings (Settings → General → Reset).

    ❓ How many devices can I connect to my smartphone's hotspot?

    Officially:

    • Android: up to 10 devices (depending on model and firmware).
    • iPhone: up to 5 devices (Apple limit).

    In practice, connecting three or more devices significantly reduces speed. For stable operation, we recommend limiting the connection to one or two devices.

    ❓ Is it possible to share Wi-Fi from my phone if it's connected to another Wi-Fi network?

    Yes, but with some reservations:

    • On Android this is called Repeater mode (not available on all firmware versions). Look for the option in Settings → Wi-Fi → Advanced.
    • On iPhone There is no such function - you can only distribute mobile Internet (3G/4G/5G), but not Wi-Fi.

    However, the speed will be lower than with a direct connection to the router.

    How do I share my phone's internet without a SIM card?

    If you don't have a SIM card but have access to Wi-Fi (for example, in a cafe or hotel), you can:

    1. Connect your smartphone to this Wi-Fi network.
    2. Turn on the access point and distribute the Internet from your phone (effectively turning it into repeater).

    On Android For this you may need an app like NetShare or WiFi RepeaterOn . iPhone There is no such function.
