Connecting a computer to the Internet via a smartphone via USB is one of the most stable and safe ways to distribute mobile traffic. Unlike a Wi-Fi hotspot or Bluetooth, a USB connection is free from interference, uses less phone battery, and provides faster data transfer speeds. This solution is especially relevant for owners PC without a Wi-Fi adapter, users on trips or in case of temporary problems with the main Internet provider.
In this article you will find step-by-step guide for phones on Android 8.0โ14, including features of settings on devices Samsung, Xiaomi, Honor and other popular brands. We will also analyze common errors (for example, NDIS error in Windows or the absence of the "USB modem" option in the menu), compare the speed of USB Internet with other distribution methods and give recommendations on choosing a tariff to avoid blocking by the operator.
If you have previously tried to connect via USB, but nothing worked, do not rush to abandon this method. In 90% of cases, the problem is solved by installing drivers or changing settings USB configurations on the phone or by adjusting the network settings in Windows. We will look at all these nuances in detail below.

Speed comparison: USB vs Wi-Fi vs Bluetooth
USB connection is often superior to other methods of Internet distribution in terms of stability and speed. Below is a comparison table for 4G network (actual values may vary depending on the operator and phone model).
| Parameter | USB modem | Wi-Fi hotspot | Bluetooth |
|---|---|---|---|
| Max. speed (Mbps) | 100โ300 | 50โ150 | 10โ30 |
| Latency (ms) | 20โ50 | 30โ100 | 100โ300 |
| Battery consumption | Low (charging from PC) | High | Medium |
| Stability | High | Medium (noise) | Low |
| Security | High (wired) | Medium (can connect) | Average |
The USB modem provides minimal speed loss compared to the phoneโs original 4G/5G connection (up to 90โ95% of the original speed), while Wi-Fi and Bluetooth can โcutโ the speed by 30โ50%.
However, USB also has disadvantages:
- โ ๏ธ Requires a physical connection (inconvenient for tablets or laptops on the move).
- โ ๏ธ Some phones block charging while the USB modem is running.
If you need maximum speed for online games or video conferencing, give preference USB modem. For mobility (for example, connecting a tablet), it is better to use a Wi-Fi hotspot.
Solving typical problems with USB modem
If the Internet via USB does not work, the reasons may be different: from lack of drivers to blocking by the operator. Let's look at the most common errors and ways to eliminate them.
1. The computer does not see the phone as a modem
Check the following:
- ๐ Are you using original cable? Cheap cables often do not support data transfer.

- Compare with the speed on a PC with a USB connection.
โ ๏ธ Attention: On phones Samsung s Android 12+ a function Saving trafficmay be triggered, which limits the speed of the USB modem. Disable it in the mobile network settings.
What to do if the operator blocks the distribution?
Some operators (for example, Tele2 or Iota) block the distribution Internet at unlimited rates. Workarounds:
1. Buy a tariff with explicit permission for distribution (for example, โUnlimited for devicesโ from MegaFon).
2. Use a VPN on your phone (sometimes this bypasses the blocking, but may violate the operatorโs rules).
3. Connect an external 4G modem (if distribution is critical for work).
How to choose a tariff for Internet distribution
Not all mobile tariffs allow Internet distribution (tethering). Many operators either block this function or limit the speed after exceeding the limit. To avoid unexpected restrictions, pay attention to the following nuances:
1. Check the terms of the tariff.
In the tariff description, look for the phrases:
- โ "Internet distribution allowed" or "No restrictions for devices".
- โ "Prohibited distribution" or "Only for one device".
Examples of tariffs with permitted distribution (for 2026):
- ๐ฑ MTS: "Tariff for devices", "Smart Unlimited".
- ๐ฑ MegaFon: "Everything for your own", "Unlimited XS/M/L".
- ๐ฑ Beeline: "It's simple", "Unlimited for everything."
2. Pay attention to the limits
Even if distribution is allowed, the operator can:
- ๐ Limit the speed after a certain amount of traffic (for example, 50 GB at maximum speed, then 128 Kbps).
- ๐ซ Block access to some services (for example, torrents or VPN).
Check these points in personal office or with the operator by phone *111# (for MTS/MegaFon) or *102# (for Beeline).
