I mean Data cable is to upload, download from Mobile (Cell) to the PC, (net), so what does Bluetooth do has what Data cable aint got or does?
Since Bluetooth is specifically designed for mobile use, in most cases it’s a bit nicer on your battery and consumes less power to do the same job as WiFi tethering does. Also like WiFi, Bluetooth is “fairly” secure. f the device you’re connecting is able to connect to your smartphone or tablet (whichever device has the data plan that you’re using to tether through), that’s probably the best option. Tethering consumes energy by expending power through the antenna to communicate with the carrier. When you connect via USB the device (we’ll call it a laptop, for the sake of simplicity) gets power via the USB cable.
