What is Personal Hotspot on iPhone and how does it work?

Modem mode (or tethering) allows you to use iPhone as an internet source for other devices - computers, tablets, or even other smartphones. Technologically, it works like this: your iPhone connects to a mobile network (3G/4G/5G) and then retransmits the signal via Wi-Fi, Bluetooth or USBIn this article, we'll focus on the most popular option—Wi-Fi sharing.

The advantages of this method:

• 🔌 Wireless — connection occurs over the air, without requiring cables or additional adapters.
• 📶 High speed — with a good 4G/5G signal, the speed can reach 100+ Mbps (depending on the operator).
• 🔄 Flexibility — you can connect several devices at the same time (usually up to 5).

However, there are limitations. Firstly, Some operators (for example, Tele2 or Yota) block Internet distribution by default on tariffs without the "Modem" optionSecondly, the active modem mode significantly reduces battery life - iPhone The battery can run out in 2-3 hours. Third, if you have limited data, its consumption will increase significantly, especially when downloading files or streaming videos.

⚠️ Important: Before activating tethering, check the terms of your plan. Some operators (such as MTS or Beeline) allow tethering but limit the speed once the high-speed data plan is exhausted. Check your account or contact your operator for details.

Preparing your iPhone for Internet sharing

Before enabling tethering, there are a few preliminary steps you should take. This will help avoid common errors, such as no network connection or connection issues.
