Access the modem using AT command passthrough

Run AT commands to validate modem status:

Manufacturer: Sierra Wireless, Incorporated Model: EM9190 Revision: SWIX55C_03.14.10.01

GPSENABLE       0x01 IPV6ENABLE      0x01 SIMLPM          0x01 IMCONFIG        0x02 DHCPRELAYENABLE 0x01

1. SSH into the R1900
 - You may connect either via LAN or the cellular interface.
2. List all interfaces
 devices
3. Access the modem using AT command passthrough
 atterm &lt;device_name&gt;
 Example:
 atterm rmnet501
4. Run AT commands to validate modem status:
 AT ATI
 Sample output:
 Manufacturer: Sierra Wireless, Incorporated Model: EM9190 Revision: SWIX55C_03.14.10.01
5. Check custom settings:
 AT!custom?
 Typical response:
 GPSENABLE 0x01 IPV6ENABLE 0x01 SIMLPM 0x01 IMCONFIG 0x02 DHCPRELAYENABLE 0x01

These values confirm modem features and configuration are active.

Failure sending AT command: If you see <code>ERROR</code> responses, ensure you’re connected to the correct modem interface (e.g., <code>rmnet501</code>).

No connectivity: Double-check APN settings, SIM provisioning on the Celona network, and that “IP WAN Subnet Filter” is disabled.

Monitoring: Use the NetCloud dashboard to verify session status and signal strength.
