The situation when a desktop router suddenly stops working, and a favorite TV series or important match is interrupted, is familiar to many owners of smart devices. In such moments mobile Internet becomes the only way to quickly restore access to online content. However, simply enabling data transfer on your smartphone isn't enough—you need to properly configure the signal broadcast to the big screen.
Modern televisions Samsung Smart TV They offer a wide range of wireless connectivity features, but pairing them with mobile devices running different operating systems has its own nuances. It's crucial to understand that sharing the internet over a mobile network consumes your data plan's bandwidth, so to watch 4K video, it's best to use a Wi-Fi router or limit the stream quality. In this guide, we'll cover all the working connection methods, from creating an access point to using dedicated apps.
Before you begin setup, make sure your smartphone has a strong cellular signal and sufficient storage space. Also, make sure the module is enabled on your TV. Wi-Fi and it's ready to search for new networks. The correct sequence of actions will help avoid authorization errors and ensure a stable image without buffering.
Preparing your smartphone for Internet sharing
The first step is to activate tethering mode on your mobile device, which turns it into a full-fledged router. On Android, this process usually takes a few seconds through the quick settings panel, while on iOS, you need to delve deeper into the settings menu. Regardless of the model, the key step is setting the network name (SSID) and a password to prevent outsiders from connecting to your channel.
iPhone owners need to go to the section Settings → Cellular → Personal Hotspot and enable the "Allow Others" switch. It's important to note that if you're using an old data plan, this feature may be blocked by your carrier, requiring you to update your terms of service. Once enabled, your smartphone's screen will glow blue or green, indicating it's ready to connect.
Android users can find the required function by following the path Settings → Connections → Mobile hotspot & tetheringHere, we recommend immediately changing the default device name to something more recognizable, such as "Home_WiFi_Phone," to avoid confusing it with neighboring networks when selecting them on your TV. You can also set a strong password in this menu to protect your data.
⚠️ Please note: When tethering, your smartphone will become very hot and drain quickly. It is recommended to keep the device connected to a charger and remove any protective case for better heat dissipation.
Connecting a Samsung TV to an access point
Once your phone has started broadcasting a Wi-Fi signal, you need to switch to the TV remote control. Go to the main menu and select Settings → Network → Network settingsThe TV will begin scanning for available wireless networks, and after a few seconds, you'll see the name you set on your smartphone.
Select your network from the list and enter the password using the on-screen keyboard. Be careful when entering characters, as they are case-sensitive. After successful authorization, a Wi-Fi icon will appear in the upper-right corner of the screen, and the system may prompt you to update the software or sign in to your Samsung account.
If the connection is established but the internet isn't working, check the data transfer status on your phone. Sometimes Android or iOS blocks large background data transfers to save data, so you may need to manually confirm the connection on your smartphone's screen.

Using Wi-Fi Direct for direct streaming
Technology Wi-Fi Direct Allows you to create a direct connection between devices without entering passwords or creating a traditional hotspot. This method is especially convenient if you simply want to stream photos or videos from your phone's gallery to your TV without using up your mobile data.
To activate the feature on your Samsung TV, go to Settings → Network → Wi-Fi Direct and turn it on. A device with a name like [TV]Samsung 6 SeriesWhen connecting, a confirmation request may appear on the TV screen, which must be accepted with the remote control.
It's worth keeping in mind that Wi-Fi Direct doesn't provide the TV with internet access. This means apps like YouTube or Netflix won't work, but the built-in media player will be able to play files stored on your phone.
Alternative methods: USB modem and apps
If your wireless connection is unstable or the speed is too slow, you can use a wired connection. Connect your smartphone to the TV's USB port using a high-quality cable. On Android devices, select "USB tethering" in the USB connection menu, after which the TV should recognize the wired internet connection.
Another effective solution is to use proprietary streaming apps such as Samsung SmartThings or Smart ViewThey allow not only screen mirroring but also content management. In this case, the phone and TV must be on the same network, or the phone must be connected to a Wi-Fi hotspot created by another device.
Advanced users can configure third-party Android-based router apps that allow for more flexible frequency band management. However, for the average user, the operating system's standard tools are usually sufficient for comfortable viewing.
| Connection method | Signal stability | Phone battery consumption | Internet access on TV |
|---|---|---|---|
| Mobile hotspot | High | Very tall | Yes |
| Wi-Fi Direct | Average | Average | No (files only) |
| USB modem | Maximum | Low (charging) | Yes |
| Screencasting (Smart View) | Depends on the router | High | No (mirroring) |
⚠️ Please note: Menu interfaces and item names may differ depending on the version of the Tizen operating system installed on your Samsung TV and the year of model release.
Solving problems with low speed and breaks
A common problem when sharing internet from a phone is slow video playback speed, constant buffering, or a complete loss of connection. This is often due to the hotspot operating on the congested 2.4 GHz band. If your smartphone and carrier plan support the network, 5G, be sure to switch the access point to this range in the modem settings.
It's also worth checking the number of connected devices. If you have a tablet, laptop, and TV connected to your phone simultaneously, your bandwidth may not be sufficient for high-quality video streaming. Disconnect unnecessary devices or lower the picture quality in the TV app settings.
In some cases, resetting the network settings on your TV can help. To do this, go to Settings → General → Network → Network ResetThis action will delete all saved passwords and settings, but often resolves issues with software conflicts with Wi-Fi module drivers.
Why does the video lag even with a full signal?
Even if the indicator shows a full signal strength, the actual speed may be low due to interference from microwave ovens, neighboring routers, or the specifics of your mobile operator's plan that limits the upload speed (TTL).
Security and traffic savings
Using mobile internet on a large screen requires special attention to data usage. One hour of watching 4K video can consume up to 7-10 GB of data. To avoid unpleasant surprises when you receive your carrier's bill, adjust your data limit in the "Data Limits" section. Mobile Hotspot → Traffic Limit on your smartphone.
Remember that an open Wi-Fi network, even with a password, is potentially vulnerable. Avoid using hotspot mode in public places unless absolutely necessary, as hackers may attempt to intercept your data. Always set a strong password containing both letters and numbers.
After you finish viewing content, be sure to turn off tethering. This will not only save battery life but also close a potential security hole for your personal information. You can set automatic shutdown in the hotspot timer.
Is it possible to share Wi-Fi if Wi-Fi is also enabled on the phone?
Most modern Android and iOS smartphones can't simultaneously receive and broadcast a Wi-Fi signal. The phone must receive internet either via a mobile network (4G/5G) or via a cable to broadcast it to the TV. Some Samsung models allow Wi-Fi connection sharing, but this requires specific settings and isn't guaranteed on all routers.
Why does the TV see the network, but says "Failed to connect"?
Most often, the cause is an incorrectly entered password or incompatible encryption standards. Try changing the security type on your phone from WPA3 to WPA2/WPA Mixed. The issue could also be a static IP address conflicting with the phone/router's address. In this case, resetting the network settings will help.
Does the phone's battery charge affect the upload speed?
Yes, directly. Many smartphones automatically reduce processor performance and Wi-Fi transmit power to conserve power when the battery level drops below 15-20%. This results in slower speeds and an unstable connection. For optimal performance, keep your phone connected to a charger.
