Tether Link Utility is a free Android app that turns your phone's mobile data into a shared connection without triggering carrier hotspot throttling or hitting a separate hotspot data cap. It uses Android's VpnService API to run a local SOCKS5 proxy — connected devices' traffic looks like normal on-device usage instead of tethering, so it bypasses the deep packet inspection carriers use to detect and throttle tethered traffic. Works around the hotspot restrictions on carriers like Verizon, AT&T, and T-Mobile (US), Jio, Airtel, and Vi (India), and Turkcell, Vodafone, and Türk Telekom (Türkiye) — no root required, no remote server, everything stays on-device. Android devices connect with a QR code scan; Windows, macOS, and iOS connect via any standard SOCKS5 proxy client (FoxyProxy, Shadowrocket, Proxifier). Free tier included; Pro removes ads and raises the device limit for heavier use.
