1. Preparing your phone: what to check before setting up

Before turning on your hotspot, make sure your phone is ready to share the internet. Here are some key points that are often overlooked:

• 📶 Mobile Internet: Make sure your phone has mobile data turned on (Settings → Connections → Mobile networks on Android or Settings → Cellular on iPhone). Without an active internet connection, distribution will not work.
• 🔋 Battery charge: Wi-Fi sharing consumes a lot of power. If the charge is below 30%, connect your phone to a charger - some models (Huawei P30 Pro, OnePlus 8T) automatically turn off the access point when the battery level is low.
• 📱 Operator restrictions: Some mobile operators (eg. Tele2 or Yota) block internet tethering on certain plans. Check your plan's terms in your personal account.
• 🔄 Software updates: Outdated firmware may cause crashes. Update your phone to the latest version (Settings → System → Software Update).

⚠️ Attention: On Android 12+ And iOS 16+ A feature has been added to automatically disable the hotspot when no devices are connected. If your laptop suddenly loses connection, check to see if your phone's Wi-Fi has been disabled.

If you use dual-SIM phone (for example, Samsung Galaxy S23 Ultra or iPhone 15 Pro Max), select the SIM card with an active internet connection in the mobile data settings. Some models only allow internet tethering from the primary SIM card.

2. Method 1: Standard access point on Android

This is the simplest method, which works on 90% of devices. The instructions are relevant for Android 10–14 (including Samsung One UI, MIUI, ColorOS and other shells).

Steps:

1. Open Settings → Connections → Mobile hotspot & tethering (on some phones the path may be different: Settings → Network & Internet → Access Point).
2. Tap on Mobile hotspot (or Modem mode on Xiaomi).
3. Turn on the slider Wi-Fi hotspot.
4. Click Set up an access point (or Wi-Fi configuration) to change:
   • 🔐 Network name (SSID): Come up with a unique name (eg. iPhone_Pro_5G instead of the standard one AndroidAP).
   • 🔑 Password: Minimum length is 8 characters. Use a combination of letters, numbers, and symbols (e.g. W7f#9Kp2!).
   • 📡 Range: Select 2.4 GHz for better compatibility with older laptops or 5 GHz for greater speed (if the laptop supports it).

Save the settings and connect your laptop to the created network.

On a laptop with Windows 10/11 or macOS Find the new network in the list of available Wi-Fi networks and enter the password. If you can't connect, try resetting the hotspot on your phone (turn it off and then back on).

FAQ: Answers to Frequently Asked Questions

Is it possible to share Wi-Fi from a phone without a password?

Technically yes, but it's extremely insecure. Without a password, unauthorized devices can connect to your network, which can lead to:

• Traffic theft (and consequently additional costs if you have a limited tariff).
• Risk of device hacking through protocol vulnerabilities Wi-Fi.
• Slowdown due to a large number of connected gadgets.

If you need to temporarily open the network (for example, for guests), use the function Wi-Fi Direct or create a guest network with a time limit (available on some phones) Samsung And Huawei).

Why does the operator block internet tethering?

Some operators (eg. Tele2 or Tinkoff Mobile) limit internet distribution on basic tariffs in order to:

• Prevent network congestion (distributing traffic to multiple devices increases the load).
• Encourage the transition to more expensive tariffs with unlimited data distribution.
• Comply with the terms of the agreement with partners (some operators lease networks from other providers and do not have the right to allow distribution).

You can bypass the blocking:

• By switching to a tariff with permitted distribution (usually these are tariffs from 500-600 rubles per month).
• Using VPN on the phone (doesn't always work, as operators block known VPN services).
• With the help of ADB-commands (see Method 5), but this may violate the terms of the agreement.

How many devices can be connected to a phone's hotspot?

The number of connected devices depends on the phone model and operating system:

• Android: Typically 5-10 devices (per Samsung Galaxy S22+ — up to 10, on Xiaomi Redmi Note 11 — up to 8).
• iOS: Maximum 5 devices (limit Apple).

When connecting a large number of devices:

• Internet speed will be shared between all connected gadgets.
• The phone battery will drain in 1-2 hours (if the phone is not connected to a charger).
• Lags and connection breaks may occur.

To connect more than 10 devices, it is better to use an external one 4G/5G router (For example, Huawei E5788 or ZTE MF286D).

Is it possible to share Wi-Fi from a phone to a TV?
