Modern Smart TV Samsung Smart TVs offer a wide range of features, but they require a stable internet connection to function properly. Situations often arise when wired internet is unavailable, and the router's built-in Wi-Fi module is temporarily inoperative or missing. In such cases, users look for a way to share Wi-Fi from their phone to their Samsung Smart TV so they can continue watching content.
There are several proven methods for establishing a wireless connection between a mobile device and a TV screen. The specific method you choose depends on your smartphone's operating system (Android or iOS) and TV models. We'll look at the most effective options for turning your phone into a fully-functional hotspot.
It is important to understand that when using mobile Internet, traffic is consumed quite quickly, especially when watching high-definition videos. 4K or 8KTherefore, before starting setup, we recommend making sure you have sufficient gigabytes in your tariff plan or are connected to an unlimited package.
Basic connection methods and their features
Before getting down to the technical details, you need to choose the optimal streaming method. There's a direct connection via an access point, where the TV "sees" the phone as a regular router, and more complex media server methods. The first option is suitable for accessing the TV's own apps, while the second is for streaming a specific video file.
The most universal is considered to be the creation of an access point Wi-Fi HotspotIn this mode, the smartphone broadcasts a cellular network signal, and the TV connects to it in the standard way. This allows you to use all built-in apps. Samsung Smart Hub, such as YouTube, Netflix or online cinemas.
The alternative is technology DLNA or protocols MiracastThey allow you to broadcast your phone's screen to a TV without using the internet, or transfer files from your device's memory. This method is often used when mobile internet is slow, but you still need to display photos or videos saved in your gallery.
It's worth considering that signal frequency also matters. Modern routers and phones support both 2.4 GHz and 5 GHz bands. If your Samsung Smart TV If you have an older model, it may not see the network in the 5 GHz range, so sometimes you have to force compatibility mode to be enabled in the phone settings.
⚠️ Caution: When using tethering, your phone may become very hot. Do not cover your device with a blanket or leave it in direct sunlight while using tethering for extended periods.
Setting up a hotspot on Android for Samsung TV
Owners of smartphones based on Android have flexible Internet sharing settings. The interface may differ depending on the manufacturer's shell (MIUI, One UI, ColorOS), but the logic remains the same. First, you need to activate tethering mode in the system settings.
Go to the settings menu and find the section Connections or Network and Internet. Select an item Mobile hotspot and modemHere you need to not just turn on the slider, but also go to the configuration settings to set the correct network name and password.
☑️ Check before connection
Selecting the frequency band is critical. In the access point settings, find the option AP rangeIf the TV does not see the network, switch the value from 5 GHz on 2.4 GHzOlder Smart TV models often do not support the new standard.
After setting up the settings, turn on the access point. On the TV remote, press the button. Home, go to Settings → General → Net. Select Wireless connection type, find your phone's name in the list and enter the password.
A successful connection will be confirmed by the appearance of the Wi-Fi icon in the corner of the TV screen. You can now launch any apps. If the speed seems slow, try disabling background downloads or app updates on your phone to free up bandwidth.
How to Share Internet from iPhone (iOS)
Ecosystem users Apple encounter some nuances when trying to connect third-party devices, such as Samsung Smart TV, to the modem mode. The main difficulty lies in the security features of iOS and device detection protocols.
First, make sure your iPhone has cellular data turned on. Go to Settings → Cellular communications and activate the item Modem mode. Turn on the switch Allow othersYour phone is now ready to search for devices, but your Samsung TV may not immediately appear in the list of available networks.
Why doesn't the iPhone share the Internet with older TVs?
Older Samsung TV models may not support the encryption standards used by iOS by default. In this case, updating the TV firmware or using third-party intermediary apps may help.
There's an important caveat: successfully connecting a TV to an iPhone often requires both devices to be previously paired via the same iCloud or Bluetooth account. If automatic discovery doesn't work, try the following:
- 📱 Turn on Bluetooth on both devices and pair them.
- 📡 In the Personal Hotspot settings on your iPhone, enable the "Maximum Compatibility" option (if available in your version of iOS).
- 🔍 On your TV, manually refresh the network list by pressing the "Refresh" button in the Wi-Fi menu.
If your TV sees the network but won't connect, the problem may be with the network name. iOS sometimes uses special characters or emoji in the device name, which Smart TV Cannot process correctly. Rename the phone to a simple name in Latin characters without spaces.
⚠️ Note: Settings interfaces may vary depending on your operating system version. If you don't find the described option, search your phone's settings by entering the word "modem."
Using the Samsung SmartThings app
Samsung has developed its own application SmartThings, which significantly simplifies interaction between your phone and TV. It's not exactly a classic Wi-Fi hotspot, but rather a local network for managing and streaming content.
For this method to work, both devices must be on the same local network. If you don't have a router, you can first share the internet from your phone (as described above), connect to the TV, and then use SmartThings for easy file transfer. This will create a bridge between the mobile device and the TV.
Install the application SmartThings from Google Play or App StoreRegister or sign in to your Samsung account. The app will automatically scan the network and offer to add your TV. Tap the device to pair.

⚠️ Note: When transferring large files via DLNA, your phone's battery may drain faster than usual. It is recommended to keep your device connected to a charger.
Troubleshooting connection issues and errors
Even with proper setup, errors can still occur. One of the most common is "Incorrect password" or "Unable to obtain IP address." If the former occurs, double-check the keyboard layout on the remote, especially if the password contains complex characters.
If the TV says it can't obtain an IP address, try changing the security type in the hotspot settings on your phone. Switch from WPA3 on WPA2New encryption standards are sometimes not supported by firmware on older TVs.
Sometimes your phone shares the internet, other devices connect, but your TV doesn't. In this case, resetting your TV's network settings will help. Go to Settings → General → Net → Network resetAfter rebooting, try connecting again.
Also, check the date and time on both devices. Time misalignment can cause security certificate errors, preventing HTTPS connections in TV apps from working, even if Wi-Fi is connected.
The impact of Wi-Fi sharing on battery life and traffic
Hotspot mode is one of the most power-hungry processes on a smartphone. The radio module operates at maximum power, which causes heat and rapid battery drain. If you plan on watching a movie for a long time, be sure to connect your phone to a charger.

One hour of watching high-definition video can use up 1 to 3 GB of data. Be careful if you don't have an unlimited plan. You can manually adjust playback quality in the YouTube and Netflix apps to save data.
Why can't the TV see the phone's access point?
The most common issue is frequency band. The phone broadcasts 5 GHz, but the TV only sees 2.4 GHz. Switch the band in the access point settings. Another possible cause is a hidden SSID; make sure the network is open for discovery.
Is it possible to share Wi-Fi via a USB cable?
Yes, it's called USB tethering. Connect your phone to your TV's USB port using a cable (if your TV supports this feature) or use an adapter. Enable "USB tethering" in your phone's settings. This will ensure a more stable connection.
How can I check how much traffic my TV has used?
Go to your phone's hotspot settings. This usually displays a list of connected devices and the amount of data transferred for each. You can also view statistics in your mobile operator's app.
Will voice control work if I share the Internet from my phone?
Yes, if the TV is connected to the Internet via a phone hotspot, all network functions, including voice control and assistants (Bixby, Alexa), will function normally.
