Using a smartphone as a modem is a common practice when landline internet service stops working or is simply unavailable. Apple device owners often face the need to provide internet access to other devices, and TCL TV This is no exception. Modern Smart TVs require a constant connection to update apps, stream content, and use voice assistants.
However, the process of distributing traffic has its own technical nuances that affect connection stability and video playback quality. iPhone This allows you to quickly create a personal hotspot, but bandwidth may be limited by your carrier's plan or cellular network signal strength. It's important to understand that a stable 4G/5G signal is required for comfortable viewing of high-definition content.
In this article, we'll cover how to properly set up tethering on iOS, find your TV in the list of available networks, and optimize the connection to minimize latency. You'll learn about hidden frequency range settings and how to resolve common pairing issues between devices across different ecosystems.
Preparing your iPhone for Personal Hotspot
Before you try to connect TCL TV, you need to make sure your smartphone is properly configured for internet tethering. The first step is to ensure you have an active SIM card with a data plan enabled. Without this, further steps are pointless, as the device will have nothing to broadcast to the outside world.
Go to the main settings of the operating system iOSFind the section for cellular communications and make sure the "Cellular Data" slider is turned on. If you're in a poor reception area, your phone may automatically turn off data to save battery, so it's a good idea to check the connection indicators in the top corner of the screen.
Next, we proceed to the actual activation of the mode. In the settings menu, select Cellular communications, and then find the option Modem modeIn some iOS versions, this option may be moved to the main Settings menu if it's already been used. Turn on the "Allow Others" switch.
⚠️ Please note: Carriers may charge additional fees for using your phone as a modem or limit speeds depending on your plan. Before using active data sharing, check the terms of your contract with your carrier to avoid unexpected charges.
An important parameter is Wi-Fi password, which is generated by default by the system. It's recommended to change it to a more complex one if you're in a public place to prevent strangers from connecting to your network and consuming your data. Write down or remember this code, as you'll need it to enter it on your TV.
Finding and connecting TCL TV to the iPhone network
Once the access point is on iPhone is active, you need to proceed to setting up your TV. Make sure that your Smart TV The TV is turned on and the remote control is within easy reach. TCL TV interfaces are based on Android TV or Google TV (on newer models), or Roku TV's proprietary interface, so menu items may vary slightly.
Take the remote control and press the button with the image of a gear or a special key Quick SettingsIn the menu that opens, select "Network." The system will offer a list of available wireless connections. Find your iPhone's name in the list, which usually matches the device name (e.g., "user's iPhone").
When you select a network, the TV will ask you to enter a password. Use the on-screen keyboard to enter the code you previously set on your smartphone. Be careful when entering characters, as they are case-sensitive. Once entered, tap "Connect."
The connection establishment process can take from 5 to 15 seconds. During this time, the TV exchanges handshake packets with iPhone and receives an IP address. If everything is successful, the "Connected" status will appear next to the network name, and the blue tethering indicator will light up in the smartphone's status bar, indicating the number of connected devices.
☑️ Connection check
Features of connection via AirPlay 2
Apple device owners can use not only the standard Wi-Fi connection, but also the technology AirPlay 2, which is built into many modern TCL models. This method not only allows the TV to access the internet but also stream content directly from a smartphone or tablet screen without the need for a complex network setup.
To use this feature, both devices must be on the same local network. If you're sharing internet from an iPhone, the TV is already connected to the same virtual network as the phone. Open Control Center on your iPhone (swipe down from the upper-right corner on newer models or swipe up on older models) and tap the "Screen Mirroring" icon.
From the list of available devices, select yours TCL TVA connection confirmation request with a four-digit code may appear on the TV screen. Enter this code on your smartphone screen to authorize. Your phone screen will then be mirrored on the larger display.
⚠️ Note: When using AirPlay to stream video from apps (YouTube, Netflix), using the "Cast" button within the app reduces network usage compared to full screen mirroring. To save battery life on your iPhone, select the "Cast" button within the player.
AirPlay 2 technology provides more stable media streaming and supports multi-room audio. However, it's important to keep in mind that when mirroring your screen permission The frame rate and resolution may be limited by the wireless channel. For viewing photos and presentations, this is an ideal option without the need for extra cables.
Problems with the 2.4 GHz and 5 GHz frequency bands
One of the most common reasons why a TV does not detect an iPhone access point is a mismatch of frequency ranges. iPhone By default, it can only distribute the network in the 5 GHz range to ensure high speed, while some Wi-Fi modules in TVs (especially budget or older TCL models) operate exclusively at a frequency of 2.4 GHz.
To resolve this issue, you need to change the tethering settings on your smartphone. Go to Settings → Modem modeFind the "Maximum Compatibility" switch. If it's off, the iPhone uses the 5 GHz band. If it's on, it switches to 2.4 GHz.
| Parameter | 2.4 GHz band | 5 GHz band |
|---|---|---|
| Transfer speed | Up to 150 Mbps | Up to 800+ Mbps |
| Range | Bigger, better at breaking through walls | Smaller, passes through obstacles worse |
| Compatibility | High (works with all TVs) | Medium (requires 5 GHz support) |
| Stability | Below (a lot of interference from neighbors) | Higher (less busy air) |
If your TV can't connect, try toggling this switch. After changing the setting, the access point will briefly reboot. You'll need to re-detect the network on your TV and enter the password. In most cases, enabling "Maximum Compatibility" mode resolves the network visibility issue.
Why is the speed lower on 2.4 GHz?
The 2.4 GHz band is heavily congested in apartment buildings. Neighbors' routers, microwave ovens, and Bluetooth devices create interference, reducing actual speeds and increasing ping times, causing video buffering.
Optimizing connection speed and stability
Sharing the internet from a smartphone is a resource-intensive process that impacts the device's battery life and connection quality. iPhone battery When actively sharing Wi-Fi, the battery drains significantly faster than usual, and the phone itself can become noticeably warm. For long movie viewing sessions, it's recommended to connect the smartphone to a charger.
Additionally, it's worth considering mobile data limits. Streaming 4K video consumes up to 15-20 GB of data per hour. If you don't have an unlimited data plan, it's best to reduce the playback quality in the TV app settings (for example, in YouTube or Netflix) to 1080p or 720p. This will save gigabytes and reduce the risk of connection drops due to bandwidth congestion.
Device placement also plays a role. Although Wi-Fi signals are omnidirectional, physical obstacles between your phone and TV can degrade the signal. Try placing your iPhone closer to the TV or within direct line of sight if you notice constant buffering.
In some cases, rebooting the network stack helps. If you're connected but the internet isn't working, try turning Airplane Mode on your iPhone. This will force the smartphone to reconnect to the cell tower and update the IP addressing.
Alternative connection methods and solutions
If standard Wi-Fi sharing doesn't produce the desired results, consider connecting via USB. Some TCL Android TV models support connecting your smartphone via a USB cable for internet access (USB Tethering technology). To do this, connect your iPhone with a Lightning to USB-C cable to the TV's USB port.
A "Trust this computer?" prompt will appear on your iPhone screen. Confirm the action. The TV should detect the new wired network connection. This method provides a more stable connection and simultaneously charges your smartphone, eliminating battery drain issues while watching.
It's also worth mentioning the possibility of using third-party router apps, although on iOS their functionality is severely limited by the security system (sandboxing). In most cases, built-in tools iOS That's quite sufficient. If the TV categorically refuses to work with the iPhone's hotspot, try resetting the network settings on the TV itself through the menu. Settings → Net → Reset.
⚠️ Note: Menu interfaces and item names may vary depending on your TCL firmware version (Android 9, 10, 11, or Google TV). If you can't find a specific item, please refer to the official documentation for your specific model or check the "About TV" section to confirm your software version.
