1. Standard Wi-Fi distribution from a phone (modem mode)

This is the most obvious and fastest way to connect your computer to the Internet via your phone. This feature is built into any Android (starting with version 2.2) and iPhone (since iOS 4.3), but the setup is a little different.

On Android the path looks like this:

2. Activate the switch Wi-Fi hotspot.
3. Click on the access point name to set it network name (SSID) And password (minimum 8 characters).
4. On your computer, find the new network in the list of available Wi-Fi networks and connect by entering the password.

On iPhone the algorithm is even simpler:

• 📱 Go to Settings → Tethering.
• 🔄 Turn on the slider Allow others.
• 🔒 You can change the network password by clicking Wi-Fi password (default is a random set of characters).
• 💻 On your PC, select the network with your iPhone's name (e.g., "iPhone from Ivan").

⚠️ Attention: Some mobile operators (eg Tele2 or Yota) may block internet tethering on plans with unlimited data. If your computer still can't connect after activating the hotspot, check your plan's terms or contact support.

Make sure that mobile Internet (3G/4G/5G) is enabled on your phone.

Disable the VPN on your phone—it may be blocking your PC's connection.

The phone's battery charge must be at least 30% (data sharing uses a lot of energy)

3. Manually change APN settings (instructions are available on forums, for example, 4PDA).

5. Setting up your computer for stable operation

How to secure your connection:

1. Always install complex password for access point (at least 12 characters, with numbers and special characters).
2. Turn off data sharing when you don't need it—even if no one is connected, your phone continues to drain battery life.
3. On Android turn on the option Turn off the access point automatically (in the modem mode settings).
