How to Share Wi-Fi from One Phone to Another: A Step-by-Step Guide

This situation is familiar to many: one phone has mobile data, while the other needs a network—for example, to download files, update apps, or make a video call. Instead of searching for a public Wi-Fi network or buying an additional SIM card, you can share internet from one smartphone to another in just a few minutes. This method works both on the go and at home if your main router is temporarily unavailable.

Modern smartphones on Android And iOS support the function modem mode (or "access point"), which turns the device into a mini-router. But not everyone knows that you can connect not only to a laptop or tablet, but also to another phone—and not only via Wi-Fi, but also via Bluetooth Or even a USB cable. In this article, we'll discuss all the methods, their pros and cons, and common mistakes that can prevent sharing.

⚠️ Important: Data transfer speed when tethering depends on your mobile carrier's plan. If you have an unlimited plan with a speed limit after a certain amount of traffic, tethering may slow down the internet on your primary phone.

1. Sharing Wi-Fi from Android to another phone

The most popular and universal way is to create Wi-Fi hotspot on Android-device. This method works on all modern smartphones, including models Samsung Galaxy, Xiaomi Redmi, Huawei, Google Pixel and other brands. The main requirement is an active SIM card with mobile internet (3G/4G/5G) or a connection to another Wi-Fi network (if the phone supports the "repeater" feature).

Instructions for Android 10 and newer (on older versions the menu may be slightly different):

1. Open Settings → Network and Internet (or Connections on Samsung).
2. Select Access point and modem (on some phones - Modem mode).
3. Tap on Wi-Fi hotspot (or Mobile hotspot).
4. Activate the slider at the top of the screen.
5. When you turn it on for the first time, the system will prompt you to set up a network name (SSID) and a password. Set them (the password must be at least 8 characters long).

Now on the second phone:

1. Open Settings → Wi-Fi.
2. Find in the list the network name that you set on the first phone.
3. Connect by entering the password.

⚠️ Attention: on some phones (eg Xiaomi with shell MIUI) the access point automatically turns off after 5-10 minutes without active connections. To avoid this, go to Additional access point settings and install Disable when no devices are present in position Never.

Mobile Internet is enabled on the primary phone | A password for the hotspot is set (at least 8 characters) | "Traffic Saver" mode is disabled on the secondary phone | Both devices are within the network coverage area (no further than 10 meters) -->

2. Sharing Wi-Fi from an iPhone (iOS) to an Android or another iPhone

On iPhone The internet sharing function is called Modem modeIt works on all models starting from iPhone 5, but there are some caveats: some mobile operators block this feature on certain plans. If the option is disabled, check your plan's terms or contact your operator.

How to enable distribution on iPhone:

1. Go to Settings → Modem mode (or Cellular communications → Modem mode on older versions iOS).
2. Activate the slider Allow others.
3. Leave the default password or change it (a combination of letters and numbers is recommended).
4. Connect the second phone to the created network via Settings → Wi-Fi.

🔹 Features of distribution from iPhone:

• 🔋 Sharing drains your battery quickly - keep it iPhone on charge if you plan to use it for a long time.
• 📶 On iPhone 12 and newer distribution is supported Wi-Fi 6, which speeds up data transfer.
• 🔒 If the second phone doesn't connect, try rebooting iPhone or reset network settings (Settings → Main → Transfer or reset iPhone → Reset → Reset network settings).

⚠️ Attention: on iPhone with dual SIM card (eSIM + nano-SIM) Internet tethering only works with one of them. Select the desired SIM card in Settings → Cellular communications → Primary SIM card for modem mode.

3. Sharing the Internet via Bluetooth

If Wi-Fi is unavailable for some reason (for example, the wireless module on your phone is broken), you can share the Internet via BluetoothThis method is slower than Wi-Fi, but it saves battery life and works more reliably in interference-ridden environments.

Instructions for Android:

1. On the main phone: Settings → Connection devices → Bluetooth → turn on visibility.
2. On the second phone: Settings → Bluetooth → Find the first device and connect (you will need to confirm the code on both phones).
3. Go back to your main phone in Settings → Access point and modem → activate Bluetooth modem.
4. On the second phone in the settings Mobile network (or Data transfer) select connection via Bluetooth.

🔹 Pros and cons of Bluetooth sharing:

⚠️ Attention: on iPhone Sharing the Internet via Bluetooth is only possible on another device iPhone or MacTo connect to Android you will have to use Wi-Fi or USB.

4. Sharing the Internet via USB cable

The most stable, but least convenient way is to connect via USB cableIt's suitable if you don't have access to Wi-Fi or Bluetooth, or if you need to share the internet with a device without wireless modules (for example, an old phone with broken Wi-Fi).

What you will need:

• 🔌 USB cable (preferably the original one, with data transfer support).
• 📱 Primary phone with support USB modem (most modern Android-devices).
• 🔄 The second phone must have a connector USB-C or Micro-USB (or adapter).

Instructions:

1. Connect the phones with a cable.
2. On the main phone: Settings → Access point and modem → turn on USB modem.
3. On the second phone, in the network settings, select USB Internet (may be called USB-ethernet).
4. Wait for the connection icon to appear in the status bar.

🔹 Important: When using USB sharing, the main phone will be charged from the second one (if it supports it) OTG), but the internet speed may be limited by the USB port version. For example, USB 2.0 will give a maximum of ~480 Mbps, and USB 3.0 — up to ~5 Gbit/s (but the actual speed depends on the operator’s tariff).

5. Typical problems and their solutions

Even with proper setup, internet tethering may not work. Here are the most common errors and how to fix them:

Problem 1: The second phone connects to the hotspot, but the internet doesn't work.

• 🔄 Restart both phones.
• 📶 Check if mobile internet is enabled on your primary phone (sometimes it turns off automatically).
• 🔒 Make sure that the second phone is not in the active mode Saving traffic or VPN.
• 🔧 Reset network settings on the second phone (Settings → System → Reset → Reset Wi-Fi, mobile network, and Bluetooth).

Problem 2: The access point keeps disconnecting.

• ⚡ Check battery saving settings - some phones (Xiaomi, Huawei) aggressively optimize background processes. Add the app Settings in exceptions.
• 🔋 Connect your primary phone to a charger - when the battery level is low (<20%), many devices automatically turn off the hotspot.
• 📱 Update your phone's firmware - for older versions Android There were bugs with Wi-Fi distribution.

Problem 3: slow internet speed.

• 📡 Check your network coverage - if the signal is weak (1-2 bars), the speed will be low regardless of the distribution method.
• 🔄 Switch your main phone to the network 4G (or 5G, if supported) in Settings → Net → Network type.
• 📵 Disable background app refresh on the second phone.

⚠️ Attention: if you use eSIM, make sure that internet tethering is enabled for this profile. On some plans, operators block the tethering feature for virtual SIM cards.

Why might operators block internet tethering?

Some mobile operators limit the tethering feature on certain plans to prevent excessive data consumption. This is because tethering is often used to connect multiple devices (laptops, tablets), which increases network congestion. If you have an unlimited plan marked "for smartphones only," tethering may be blocked or limited in speed. To clarify the terms, check the plan description in your operator account or call support.

6. Comparison of distribution methods: which one to choose?

Each method has its pros and cons. The choice depends on your goals:

🔹 Recommendations for selection:

• 🎮 For online games or video calls (Zoom, Discord) choose Wi-Fi - it provides minimal delays.
• 📞 For voice calls (WhatsApp, Telegram) or working with documents enough Bluetooth.
• 🔌 If necessary long-term connection (for example, to update software), use USB - it doesn't drain the battery.

7. Security when sharing the Internet

Sharing Wi-Fi from your phone creates an open (or password-protected) network that other devices can connect to. To prevent unauthorized access and data leakage, follow these guidelines:

• 🔐 Always install complex password for the access point (at least 12 characters, with letters and numbers). Avoid simple combinations like 12345678 or password.
• 📱 Turn off the access point when it is not needed - this will reduce the risk of connecting to unauthorized devices.
• 🔍 Regularly check the list of connected devices in your hotspot settings. If you see an unknown one, change the password.
• 🛡️ On Android You can restrict access to the access point by MAC address (in some firmware, for example, MIUI).

⚠️ Attention: If you share internet in a public place (cafe, airport), there's a risk that someone could intercept your traffic. Avoid entering bank or social media passwords over the shared network. For protection, use VPN on the second phone.

On some phones (eg. Samsung Galaxy S22 (And newer) has a "5G Hotspot" feature that encrypts traffic at the hardware level. Enable it in the hotspot settings for additional security.

FAQ: Frequently asked questions about sharing Wi-Fi from your phone

❓ Why is the internet slow when sharing?

There are several reasons:

1. Weak mobile network signal (check the number of antenna divisions).
2. Speed ​​limitation by the operator (for example, after high-speed traffic is exhausted).
3. Interference from other Wi-Fi networks (try changing the channel in the access point settings).
4. Background updates on the second phone (turn off automatic app updates).

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

The maximum quantity depends on the phone model:

• Android: usually 5-10 devices (on flagship models up to 15).
• iPhone: up to 5 devices simultaneously.
