Engadget's guide explains USB tethering as a wired alternative to wireless hotspots. It allows sharing a phone's cellular data via a cable, offering stability in crowded areas and preventing network exposure. Samsung users can enable it by connecting via USB and toggling the option in Settings > Network & internet > Hotspot & tethering. Apple devices require trusting the computer and enabling Personal Hotspot in Settings. Microsoft's Apple Devices app or iTunes may be needed for iPhone-to-Windows tethering.

USB tethering suits single-device use due to data limitations and carrier restrictions. iPhone users should note background data usage and potential extra charges. While wired connections are steadier than wireless, they depend on cellular signal quality. Will Shanklin highlights that USB tethering isn't a full hotspot replacement, especially for multiple devices.

Key considerations include cable type (data-capable required for Android) and carrier policies. Users should verify plan details before tethering. The method works for Android-to-Windows, iPhone-to-Mac/Windows, but Android-to-Mac is unsupported.
