MoMo Registration Process

1. On initial power-on, MoMo checks for existence of a SIM card.
   • If a SIM exists, continue.
   • Else, go into deep sleep. Rinse and repeat.
2. MoMo sends a registration text message to the server, then goes into "waiting for sensing" mode
3. The mechanic who installed the device sends a text message to the server with the new MoMo's GSM number
   • He/she is now the assigned mechanic for this MoMo and will receive any critical updates in real-time.
4. Assuming the device has already registered, the server responds to the mechanic confirming that the device is active
   • If the device hasn't registered yet, the server says so and the mechanic will have to debug the device's potential connectivity issue.
