However, finding this support in the settings can be difficult, especially if the operating system interface iOS updated or you changed the device model.
In this article, we'll take a detailed look at where to find the required menu item, how to properly activate the mode, and what to do if standard methods don't work.
The main location of the function in the settings menu
Finding the location of a Wi-Fi hotspot on your iPhone starts from the main menu. Settings.

☑️ Connection diagnostics
Using USB and Bluetooth for sharing
A wireless connection is not always the best option, especially when stability and data transfer speed are important.
Connection via cable Lightning or USB-C provides a more reliable communication channel and charges the phone at the same time.
To do this, you need to connect the cable to the computer and select in the menu on the phone screen Trust this computer.
The system will automatically detect a new network connection, and the Internet will appear without entering a password.
An alternative to cable is a connection via Bluetooth, which consumes less energy but runs slower.
To set up this type of connection, you need to pair the devices through the Bluetooth menu, and then in the computer's network settings, select the connection via iPhone.
This method is convenient for older laptops or desktop PCs that are not equipped with a Wi-Fi module.
⚠️ Attention: When using a USB cable, make sure it is original or certified by the program. MFiCheaper alternatives can only transmit electricity, not data, making internet distribution impossible.
The choice of connection method depends on your priorities: speed and stability (USB), versatility (Wi-Fi), or battery saving (Bluetooth).
The impact of tethering on battery life
Active internet distribution is an energy-intensive process that significantly accelerates battery drain.
Radio module Wi-Fi operates in a constant signal transmission mode, which creates a high load on the power supply system.
The battery drains especially quickly when using 4G/5G networks in areas with poor reception, when the phone is constantly searching for a signal.
If you plan to use the router for a long time, it is recommended to keep the device connected to a power source.
Using an external power bank will be an excellent solution for working in the field.
You can also lower your screen brightness and close background apps to extend battery life a little.
- 🔋 Connect the charger when using for a long time.
- 📉 Reduce screen brightness to save power.
- 📵 Turn off network scanning if you are in an area without coverage.
Modern models iPhone are equipped with optimized batteries, but the physics of the process remain the same: powerful data transfer requires energy.
Keep an eye on your case temperature, as the system may automatically limit performance when it gets too hot.
Is it possible to share the Internet if the phone doesn’t have a SIM card?
No, to share mobile data, you need an active SIM card with a data plan. Without a SIM card, your phone can only serve as a Wi-Fi repeater (using special apps or a jailbreak), but not as a source of mobile data.
Why is the access point green but the internet is not working?
A green light means the transmission module is active, but this doesn't guarantee access to the global network. Check your account balance, available data plan, and coverage area. The issue may also be caused by incorrect APN settings on your carrier.
How many devices can connect to an iPhone at the same time?
Technically, the iPhone supports up to five simultaneous Wi-Fi connections. However, the actual number depends on the iOS version, phone model, and processor load. Connecting multiple devices will significantly reduce the internet speed on each device.
Does the operator charge extra for modem mode?
Terms and conditions depend on your tariff plan. Some operators include data tethering in the basic package, while others require an additional option or block it. It's recommended to check the terms and conditions in your personal account or with your operator's app to avoid unexpected charges.
