5. Usage
- Do not hot-plug devices: Always power off before inserting/removing SIM cards, antennas, or the module to prevent damage or recognition issues. After powering on, if registration is successful, the NET indicator will blink.
- Ensure the SIM card is valid: It is recommended to first test with a standard mobile SIM card. Avoid IoT cards with strict limitations. Try SIM cards from different carriers to rule out card failure, insufficient balance, or compatibility issues.
5.1 Status Indicators
| NET | Status |
|---|---|
| Off | Powered off or starting up |
| On | Searching for network |
| Blinking | Connected, working normally |
| On/Blink | Shutting down |
The status indicator reflects the module’s internal state. To communicate with the development board, additional configuration is required. After configuration, the board can access the network via the module.
