The modern smartphone has long ceased to be just a device for making calls, having become a full-fledged mobile office and entertainment center. iPhone SE 2020, equipped with a powerful processor A13 Bionic, works perfectly as a router in the field. When landline internet is unavailable or your provider is down, the personal hotspot function becomes the only way to access the internet on a laptop or tablet.
Device owners often wonder how to properly activate tethering mode to ensure a stable connection and avoid draining the battery within a couple of hours. The setup process in the operating system iOS It's as simplified as possible, but it hides a number of nuances that affect speed and compatibility with other devices. In this article, we'll cover every configuration step in detail, from basic settings to advanced signal optimization methods.
It's worth noting that the quality of the data transfer directly depends on your cellular network reception and your carrier's data plan. Before setting up, make sure you have sufficient data on your account, as high-definition videos or downloading large files can quickly exhaust your data allowance. Next, we'll move on to the technical part and cover a step-by-step procedure.
Basic hotspot activation in iOS
Initial setup of the function Modem mode It literally takes a few seconds if the operator has already transferred the necessary profiles to the device. First, open the main menu and go to the system settings section. Here, you'll need to select the option that may be called "Cellular" or "Modem Mode," depending on the firmware version and menu configuration.
Inside the menu, find the "Allow Others" switch and toggle it to the on position. The system may prompt you to confirm the action via a pop-up window, where you'll need to select "Turn on Wi-Fi and Bluetooth." This will start broadcasting the signal, making your iPhone visible to surrounding devices.
A critical security element is the password, which is automatically generated by default but can be changed by the user. It is recommended to use a complex combination of characters to prevent unauthorized access to your traffic. The password can be changed in the same menu by clicking on the corresponding line and entering a new combination of at least 8 characters.
☑️ Pre-launch check
⚠️ Attention: If the "Modem Mode" option is missing or grayed out, contact your mobile carrier's support team. Manual activation of the service by your provider or updating network settings is often required.
Frequency range adjustment and compatibility
One of the key features of Internet distribution on devices Apple is the ability to select a frequency range. iPhone SE 2020 It supports 5 GHz, which provides high speeds but has a shorter range and is less effective at penetrating walls. Older devices or budget laptops may simply not see the network if it operates at a higher frequency.
To ensure maximum compatibility with all devices, including gaming consoles and older Ultrabooks, we recommend switching to the 2.4 GHz band. This can be done through the "Maximum Compatibility" menu. Enabling this mode will slightly reduce potential data transfer speeds, but it ensures that any Wi-Fi-enabled device will detect your access point.
Choosing the right band is especially important in apartment buildings, where the airwaves are heavily polluted by signals from neighboring routers. The 2.4 GHz band often experiences interference, so it sometimes makes sense to sacrifice compatibility for 5 GHz speeds if the connected device supports this standard.
Connecting devices via Wi-Fi, USB, and Bluetooth
There are three main ways to share an internet connection with iPhone to other gadgets, and each of them has its own advantages. Wireless connection via Wi-Fi This is the most popular and convenient method, requiring no extra wires. To connect, simply find the network with your phone's name in the list of available networks on the client device and enter the password.
Connection via USB cable Provides the most stable connection while simultaneously charging the smartphone, which is critical for long-term use. When using a Lightning cable (or USB-C in newer models, although the SE 2020 uses Lightning), the computer treats the phone as a network card, eliminating the speed losses and latency associated with wireless communication.
The third option is - Bluetooth — Rarely used due to its low data transfer speed, but can be useful in emergency situations when other methods are unavailable. This method requires pairing devices and setting up a PAN network, which takes longer but consumes less power than an active Wi-Fi module.
| Connection method | Speed | Stability | Battery consumption |
|---|---|---|---|
| Wi-Fi (5 GHz) | High | Average | High |
| Wi-Fi (2.4 GHz) | Average | Average | High |
| USB cable | Maximum | High | Charger |
| Bluetooth | Low | Low | Short |
Optimize power consumption and work in the background
Sharing the internet is one of the most energy-intensive processes for a mobile device. Wireless modules operate at full power, and the processor is constantly processing data packets, which causes the device to heat up quickly. iPhone SE 2020To minimize the impact on battery life, the system automatically turns off the access point if no one is connected to it for a long time.
To extend the tethering time, it's recommended to reduce screen brightness or turn off the display completely immediately after connecting the client device. The screen is one of the largest energy consumers, and turning it off can increase the connection time by 30-40%. It's also a good idea to close background apps that may consume data.
If you plan to use your phone as a stationary router for an extended period, it's best to connect it to a power source. However, you should monitor the device's temperature: overheating can lead to throttling (reduced performance) and temporary shutdown of the data sharing function until it cools down.
Troubleshooting and common errors
Despite the stability of work iOSUsers may encounter situations where other devices cannot see the access point or cannot obtain an IP address. The first step in troubleshooting is checking for a cellular network signal. If the indicator shows "No Network" or "Searching," internet tethering will not work, even if the slider is enabled.
A common issue is network settings becoming out of sync. In this case, resetting the network settings can help, returning all connection parameters to factory defaults.
Sometimes the problem lies with the connecting device itself, which is attempting to use older security protocols. Make sure the wireless adapter drivers on the client device are updated and the operating system is up to date. You should also try "Forgetting the Network" on the client and reconnecting.
⚠️ Attention: If the issue persists after resetting network settings, check if your iPhone has an enterprise management (MDM) profile or parental controls that may be blocking the tethering feature.
How to reset network settings?
Go to Settings → General → Transfer or reset iPhone → Reset → Reset network settings. Your device will restart and you'll need to re-enter your Wi-Fi passwords.
Security issues when using networks
Using iPhone By using a Wi-Fi hotspot, you create your own secure network, which is significantly safer than connecting to open Wi-Fi hotspots in cafes or airports. Data is transmitted through an encrypted cellular network, preventing nearby attackers from intercepting your traffic.
However, don't make the network public. Make sure the device name is hidden in the hotspot settings (if this option is available in your iOS version via privacy settings) and a strong password is set. Avoid using simple combinations like "12345678" or your date of birth.
When connecting corporate laptops or devices containing sensitive information, always use a wired connection or ensure the device has up-to-date antivirus and firewall software installed. While the risk of Wi-Fi hacking is minimal with modern encryption protocols, vigilance is still essential.
