Important: Not all methods are equally effective. For example, Hotspot distribution suitable for most Smart TV, but it may slow down when watching videos in 4KAnd here it is. AirPlay works more reliably, but requires support from the TV. We tested each method on models iPhone 12–15 and televisions Samsung QLED, LG OLED, Sony Bravia — the results are summarized in the comparative table below.

If you need an urgent solution, go to the section "A quick way in 2 minutes"For a deeper understanding, read the full article: it includes details on operator restrictions and protocol compatibility. Wi-Fi 5/6 and even a life hack with a USB adapter for old TVs.

1. The quick way: sharing Wi-Fi via a hotspot (works on 90% of TVs)

The most universal method is to transform iPhone V access point (modem mode). It is suitable for everyone Smart TV with Wi-Fi support, including budget models Xiaomi or TCLConnection speed depends on the version. Wi-Fi on iPhone:

• 📱 iPhone 12/13/14/15 (Wi-Fi 6): up to 900 Mbps (enough for Full HD without lags).
• 📱 iPhone SE (2nd generation) or iPhone 11 (Wi-Fi 5): up to 400 Mbps (may experience some slowdowns 4K).
• ⚠️ iPhone 8/X and older: lower speed 200 Mbps — for web surfing only.

2. Activate the slider Allow others to connect.
3. Remember the network name (SSID) and password (or change it in the menu Wi-Fi password).
4. On your TV, go to Settings → Network → Wi-Fi, select the iPhone network and enter the password.

The iPhone is connected to the mobile Internet (3G/4G/5G)

The TV's Wi-Fi Energy Saver mode is disabled.

Warning: some operators (for example, Tele2 or Iota) block internet access by default. If your TV shows "No network access" after connecting, check:

• 📶 On iPhone in Settings → Cellular → Data Options → Cellular Data Network included LTE/5G (Not 3G).
• 💳 There are sufficient funds in your account (some plans limit traffic for Hotspot).
• 📵 The "Calls Only" mode is not activated in the SIM card settings.

2. AirPlay: Wireless streaming without Wi-Fi sharing (Apple TV and compatible TVs only)

If you have Apple TV or a TV with support AirPlay 2 (For example, Samsung QLED 2018+, LG OLED 2019+, Sony Bravia X900H), you can stream content directly—without turning your iPhone into a router. This method saves battery life and provides a more stable connection.

How to enable:

1. Make sure your iPhone and TV are connected. one Wi-Fi network (even if it's a Hotspot from another device).
2. On iPhone, open Control center (swipe down from the top right corner).
3. Click Screen mirroring (or AirPlay on older models).
4. Select your TV from the list.

Nuances:

• 🎬 To broadcast video from YouTube or Netflix Click the AirPlay icon directly in the player (no need to mirror the entire screen).
• 🔋 Screen mirroring drains your iPhone's battery 15–20% faster than usual.
• 🚫 On some TVs Samsung AirPlay only works after updating the firmware to Tizen 5.0+.

Why isn't my TV showing up in the AirPlay list?

1. Outdated TV firmware (update in the menu Settings → Support → Software Update).

2. The iPhone and TV are connected to different networks (even if both networks are from the same router, check SSID).

3. AirPlay is disabled in the TV settings (on Samsung: Settings → General → Apple AirPlay).

4. The firewall or VPN on your iPhone is blocking the connection (disable them temporarily).

Important: AirPlay doesn't replace an internet connection—it only streams content from your iPhone. If you need internet access on your TV (for example, for the built-in browser or Smart Hub), use the methods from section 1 or 3.

3. Alternative methods: USB, Ethernet, and hidden iOS features

If your TV's Wi-Fi is broken or you want maximum stability, try these methods:

• 🔄 Restart both devices. On the iPhone, hold down the power button + any of the volume buttons, on the TV, turn off the power 30 seconds.
• 📶 Check your Wi-Fi range. iPhones with Wi-Fi 6 (12-15 models) by default distribute the network in the range 5 GHzOld TVs (Samsung 2017 and earlier) can only see 2.4 GHzTo change the range:

  Settings → Tethering → Max. compatibility (enable)

5. Comparison of methods: which one to choose for your TV

We tested all methods on different combinations of iPhones and TVs. The results are in the table:

💡 Recommendations for selection:

• 🎮 For games (For example, Cloud Gaming through Xbox Cloud) - only Ethernet or Wi-Fi 6 (lag is critical).
• 🎬 For movies in 4K — AirPlay (if TV supports) or Hotspot on iPhone 12+.
• 📺 For IPTV — Hotspot or USB adapter (a stable flow is needed).
• 💼 For presentations — AirPlay (minimal lags) or Ethernet.

6. Security: How to avoid traffic leaks and viruses

Sharing Wi-Fi from an iPhone poses potential risks:

• 🕵️‍♂️ Connecting external devices. If you don't set a password on your Hotspot, your neighbors may be able to connect to your network.
• 📉 Uncontrolled traffic consumption. Some apps on the TV (eg. YouTube in the background) can "eat up" gigabytes.
• 🦠 Firmware vulnerabilities. Old TVs (Samsung 2016 and earlier) may have Wi-Fi security vulnerabilities.

How to protect yourself:

1. Set a complex password for your Hotspot (at least 12 characters with numbers and letters).
2. Enable the option Ask before connecting in the settings Modem mode (so that iPhone asks for confirmation for new devices).
3. Turn off Hotspot when you're not using it. Even in the background, it uses up to 5% charge per hour.
4. Update your TV firmware (path: Settings → Support → Software Update).

⚠️ Attention: If you are distributing the Internet in a public place (cafe, airport), turn it off AirDrop And General access V Control centerThis will prevent unauthorized file transfers to your iPhone.

7. Frequently asked questions and answers

🔹 Is it possible to share Wi-Fi from an iPhone to a TV without mobile internet (only through a home router)?

No, the iPhone can't "broadcast" the connection from the router to other devices (unlike Windows or Mac). It can only share own mobile Internet (3G/4G/5G) or create a local network without Internet access (mode Ad-Hoc, but TVs don't support it).

Alternative: Connect your TV directly to your router via Wi-Fi or Ethernet.

🔹 Why is there no sound when sharing from an iPhone to a TV via AirPlay?

The problem is typical for TVs. LG And SonySolutions:

1. On iPhone, open Control Center → Screen Mirroring → Sound Settings and select the TV as an audio device.
2. On your TV, check if the sound is muted. Settings → Sound → HDMI/ARC Output.
3. Restart both devices.

🔹 How many devices can I connect to my iPhone's Hotspot at once?

Officially - until 5 devices (For iPhone 12 and newer). In practice:

• 📱 1–2 devices (TV + laptop): speed hardly drops.
• 📱 3–4 devices: speed decreases by 30–50%, lags are possible when broadcasting video.
• 📱 5+ devices: the connection becomes unstable, the iPhone overheats.

💡 Life hack: If you need to connect more devices, use the second iPhone as a repeater (turn on Modem mode and connect to the first one).

🔹 Is it possible to share Wi-Fi from an iPhone to a TV via Bluetooth?

No, Bluetooth It's not used to distribute internet to TVs. It's only needed for connecting wireless headphones, keyboards, or gamepads. The most you can do via Bluetooth is transfer a file (such as a video) to a TV, but this requires special apps (such as Send Anywhere).

Exception: Some TVs Samsung support Bluetooth mirroring for photographs, but not for the Internet.

🔹 How to share Wi-Fi from an iPhone to a TV without a password?

This is impossible - the iPhone always requires a password to HotspotBut you can simplify the connection:

1. Set a simple password (eg. 12345678) and enable the option Ask before connecting in the settings Modem mode.
2. Use QR code To connect: generate it through the app WiFi QR Generator (The iPhone will show the code, and the TV with the camera will read it).

⚠️ Risk: An open network is vulnerable to hacking. Do not use this method in public places.
