Tethering means using your Realme phone's mobile data connection to get another device online. Instead of connecting a laptop or tablet directly to a router, that device connects through your phone, which acts as a small mobile router. This is useful when you are traveling, when your home internet is down, or when a second device simply has no other way to reach the internet.
Realme UI groups all tethering options under one connectivity area, but the three methods behave quite differently. Understanding what each one is good for helps you avoid slow connections or unnecessary battery drain.
Wi-Fi hotspot
A Wi-Fi hotspot turns your phone's mobile data into a wireless network that other devices join like any normal Wi-Fi. This is the most flexible option because several devices can connect at once, and none of them need a cable. It is the best choice for laptops, smart TVs, or friends who need a quick connection.
The trade-off is battery and data use. Broadcasting Wi-Fi and forwarding traffic for multiple devices puts more load on the phone than a single cable connection would, and it is easy to lose track of how much data everyone is using.
USB tethering
USB tethering shares your mobile data through a cable connected to a computer. Because the connection is wired, it is typically more stable and often faster than Wi-Fi hotspot, and the phone charges at the same time instead of losing battery.
This method only supports one connected device at a time and requires the right cable and, on some computers, a driver to recognize the connection. It suits situations where you are working at a desk and want a dependable link rather than a mobile one.
Bluetooth tethering
Bluetooth tethering shares data over a much slower wireless link, but it uses far less battery than Wi-Fi hotspot. It works well for light tasks like checking email or messaging on a laptop when battery life matters more than speed.
Because Bluetooth bandwidth is limited, it is not a good fit for video streaming, large downloads, or video calls.
What to keep in mind
- All tethering methods draw from your regular mobile data plan, so tethering can use up a data cap quickly, especially over Wi-Fi hotspot.
- Some mobile carriers apply separate rules or limits to tethered data, even on unlimited plans.
- A hotspot password prevents strangers from joining your connection and using your data without permission.
- Closing the hotspot or tethering connection when it is not in use saves battery and avoids accidental data use.
Choosing the right method comes down to how many devices need access, how fast the connection needs to be, and how much battery or data you can spare. Wi-Fi hotspot covers most everyday needs, USB tethering suits stationary work, and Bluetooth tethering is the fallback for light, battery-conscious use.
