How to Use the Internet on Another Phone via Wi-Fi: A Complete Guide

It's a familiar situation: you have a smartphone with mobile data, but another device urgently needs internet access. Perhaps a friend has run out of data, or you want to connect a tablet without a SIM card. Internet sharing via Wi-Fi — the simplest solution, but not always obvious for beginners.

This article will help you figure out how to turn your phone into Wi-Fi hotspotso that other devices can use its internet. We'll look at the settings for Android And iOSWe'll explore common mistakes and offer safety tips. You'll also learn how to save battery life during long-term sharing and why speeds sometimes drop.

Spoiler alert: the process takes no more than a minute if you know all the nuances. But there are some pitfalls—for example, Some operators block Internet tethering on tariffs with unlimited traffic., even if the function technically works. More on this and other important details below.

What is Wi-Fi Internet sharing and how does it work?

When you turn on access point mode on your smartphone, it starts working as a mini-router. Your phone connects to the mobile network (3G/4G/5G) via the SIM card, and then retransmits this signal via Wi-Fi to other devices. To them, it looks like a regular wireless network—just like the one you use at home with your router.

Technically, the process is based on two protocols:

• 📡 NAT (Network Address Translation) - allows multiple devices to share your phone's public IP address.
• 🔄 DHCP (Dynamic Host Configuration Protocol) — automatically assigns local IP addresses to connected gadgets.

Internet speed when distributing will depend on:

• 📶 Mobile network quality (for example, 5G is faster than 4G, but has worse coverage).
• 📱 The phone's processor power (weaker models may lag when actively distributing data).
• 🔋 Battery status (when battery is low, some phones limit performance).

It is important to understand that Internet distribution consumes your basic plan's trafficIf you have a limited data plan, monitor your usage—especially if you connect devices that update apps or stream videos in the background.

Preparing Your Phone for Wi-Fi Sharing: 5 Essential Steps

Before turning on your hotspot, perform some simple preparation. This will help avoid connection and speed issues.

1. Check your remaining traffic

Open your mobile operator's app or send a USSD request (for example, *100# For MTS, *111# For Beeline). Make sure you have enough gigabytes—sharing data eats up your data faster than regular usage on a single device.

2. Update the software

Outdated firmware may cause problems with your access point. Go to Settings → Software Update (For Android) or Settings → General → Software Update (For iPhone) and install the latest patches.

3. Disable power saving mode

Functions like Adaptive battery (Android) or Low power mode (iOS) can automatically disable the hotspot when the battery is low. It's best to disable them beforehand:

Settings → Battery → Low Power Mode → Disable

4. Check your mobile network settings

Make sure your data connection is turned on and the correct network type is selected (e.g. 4G/5G instead of 3G only). Path:

• 📱 Android: Settings → Mobile network → Preferred network type
• 🍎 iOS: Settings → Cellular → Data Options → Voice & Data

5. Make sure there are no operator restrictions

Some plans (especially those with "unlimited" internet) block Wi-Fi distribution or limit speed. For example, Tele2 Previously, the speed was reduced to 64 kbps when uploading data on "My Tele2" plans. Check the terms in your operator's personal account.

How to Enable a Mobile Hotspot on Android: Step-by-Step Instructions

The interface may differ slightly depending on the version. Android and shells (MIUI, One UI, ColorOS etc.), but the general algorithm is the same.

Step 1: Open your hotspot settings

Go to:

Settings → Wireless & networks → Hotspot & tethering → Mobile hotspot

On some phones (eg. Xiaomi) the path can be:

Settings → Connections and Sharing → Personal Hotspot

Step 2: Configure network settings

Click on Setting up an access point (or Wi-Fi configuration) and indicate:

• 🔐 Network name (SSID) - any convenient (for example, MyPhone_Hotspot).
• 🔑 Security type — choose WPA2 PSK (the most reliable).
• 🔑 Password — at least 8 characters (use letters, numbers and symbols).

Step 3: Turn on the hotspot

Activate the switch Mobile hotspot. After a few seconds, an icon will appear next to the mobile network icon. 📶→📱, signaling active distribution.

Step 4: Connect the second device

On the second phone (or tablet), find the Wi-Fi network you created in the list of Wi-Fi networks, enter the password, and connect. Done!

How to Share Wi-Fi from iPhone (iOS): Features and Limitations

On iPhone The internet sharing function is called Modem mode and has its own nuances. For example, Apple Automatically turns off the hotspot if no devices are connected to it for 90 seconds (this can be changed).

Step 1: Enable tethering

Go to:

Settings → Tethering

Activate the switch Allow othersIf the option is grayed out, check:

• 📶 Is mobile data enabled? (Settings → Cellular → Cellular Data).
• 📱 Does your plan support tethering (some carriers require an additional option).

Step 2: Set up a password

Click on Wi-Fi password and set a new one (default Apple (generates randomly). We recommend using at least 10 characters with numbers and letters.

Step 3: Connect the second device

On the second phone (even if it is Android) find the network with your name iPhone (For example, Ivan's iPhone), enter the password and connect.

iOS Features:

• 🔄 Auto power off: To keep the access point running constantly, go to Settings → Tethering → Auto-disconnect and choose Never.
• 🔌 Connection via USB/Bluetooth: iPhone It can also distribute the Internet via cable or Bluetooth (useful if Wi-Fi is unstable).

Why does iPhone ask for confirmation when connecting a new device?

This is a function Family Sharing or Notifications about new connectionsIt protects against unauthorized access. To disable it, go to Settings → Tethering and deactivate the option Request confirmation (if it is available in your iOS version).

Common problems and their solutions

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

If nothing helps:

• 🔄 Restart both devices.
• 📱 Reset network settings on your primary phone (Settings → System → Reset → Reset Wi-Fi & network settings).
• 📡 Check if a VPN is enabled on the second device—it may be blocking traffic.

How to save battery life when sharing Wi-Fi

Sharing your internet connection is one of the most power-hungry features on a smartphone. Here's how to reduce battery drain:

1. Limit the number of connected devices

Each new device increases the load on the processor and Wi-Fi module. Optimally, no more than 2-3 gadgets simultaneously.

2. Reduce screen brightness

Even if you don't use your phone while sharing, background processes (like email syncing) drain your battery. Reduce brightness to minimum or turn it on. Adaptive brightness.

3. Disable unnecessary background processes

Close all applications except those needed for sharing, especially the data-hungry ones:

• 🎮 Games (if they are running in the background).
• 📷 Photo/video editing apps.
• 🎵 Music streaming services.

4. Use a charger

If you have to distribute the signal for a long time (for example, outdoors), connect the phone to powerbank or a network adapter. Modern smartphones support reverse charging - you can charge the second phone directly (but this drains the battery of the main one even more).

5. Switch to USB tethering mode (for Android)

Connecting via cable consumes less power than Wi-Fi. To do this:

1. Connect the phones with a cable USB-C/USB-A (OTG adapter may be required).
2. Turn it on on your main phone USB modem in the access point settings.

Security: How to Protect Your Access Point from Hacking

An open access point is an invitation to hackers. They can not only "steal" your traffic but also intercept data (passwords, messages). Follow these rules:

1. Always use a complex password

Avoid simple combinations like 12345678 or qwerty. Good password:

• 🔑 Length must be at least 12 characters.
• 🔤 A mixture of uppercase and lowercase letters, numbers, symbols (P@ssw0rd!2026).
• 🚫 Not linked to your personal data (date of birth, name).

2. Enable hidden network mode (SSID)

This won't make the network completely invisible, but it will reduce the number of accidental connections. How to enable:

Access point settings → Advanced → Hide network (or "Do not broadcast SSID")

Cons: You will have to manually enter the network name on the connected devices.

3. Limit the number of connected devices

In the access point settings (Android) you can specify the maximum number of gadgets (usually from 1 to 10). Set the value 2-3 - this is enough for most tasks.

4. Monitor connected devices

Periodically check who is connected to your network:

• 📱 Android: Settings → Access Point → Connected Devices.
• 🍎 iOS: the list of connected gadgets is displayed directly in Modem mode.

If you see an unfamiliar device - change your password immediately.

5. Use a VPN on your main phone

If you share the Internet in a public place, turn on a VPN (for example, ProtonVPN or Windscribe). This will encrypt your traffic and protect it from data interception.

FAQ: Answers to Frequently Asked Questions

Can I share Wi-Fi from my phone if I have an unlimited data plan?

It depends on the carrier. Some block data transfer on "unlimited" plans or limit the speed (for example, to 128 kbps). Check the terms in your account or call support. Often, you'll need to activate an additional option (paid or free).

Why does the battery drain quickly when distributing Wi-Fi?

Internet sharing uses several phone modules at once: mobile network, Wi-Fi, CPU (for traffic routing) and antennaThis increases power consumption by 2-3 times. To save battery, reduce screen brightness, disable background apps, and use a charger.

Is it possible to share internet from one iPhone to another?

Yes, but there are some nuances:

• 🍎 Data transfer must be enabled on both phones.
• 📶 The operator must not block the distribution (check with support).
• 🔄 A notification may appear on an iPhone that is sharing the Internet. Connect via USB to access the Internet - confirm it.

How to increase the range of an access point?

The range depends on the phone's Wi-Fi module's power (usually 5-10 meters indoors). To improve coverage:

• 📶 Place the phone in the center of the room, away from walls and metal objects.
• 🔋 Connect your phone to a charger - when the battery is low, the transmission power decreases.
• 🛠️ Use a Wi-Fi repeater (if the distribution is constant).

On Android You can try changing the Wi-Fi channel manually (in the access point settings) if there is interference from other networks.

What should I do if my operator blocks internet access?

There are several workarounds (but they may violate the operator's rules):

• 🔄 Changing APN: Sometimes manual configuration of the access point helps (find the current parameters for your operator on the Internet).
• 📡 Bypass applications: For example, PDANet+ or ClockworkMod Tether (require root rights on Android).
• 💳 Change of tariff: activate the distribution option (usually costs 50-150 rubles/month).

⚠️ Warning: Using these workarounds may result in your SIM card being blocked. Check your carrier's policies before experimenting.
