## What is Relay 5G?

Relay is a $199 USB-C 5G dongle that plugs directly into any MacBook and provides cellular internet via macOS's native USB networking stack. No drivers, no app, no hotspot, no phone involved. macOS detects it as an ethernet adapter automatically.

Includes a nano-SIM tray for your own carrier SIM. eSIM with included data is planned (provisioning architecture under validation with partners). Designed and assembled in Austin, Texas.
