Teltonika LTE routers are widely used in IoT, industrial, and remote networking applications. Setting up a Telnyx SIM on a Teltonika router ensures a secure and reliable cellular connection. This guide provides step-by-step instructions to configure a Teltonika LTE router with a Telnyx SIM—and adds robust failover recovery with auto-reboot, plus RMS cloud integration for managing large SIM fleets.
1. Initial Setup
Insert the SIM Card:
Power off the router.
Insert your active Telnyx SIM into the designated SIM slot.
Ensure the SIM is securely seated to prevent connectivity issues.
Connect to Power and Computer:
Power on the router using the included adapter.
Use an Ethernet cable to connect the router’s LAN port to your computer.
2. Accessing the Web Interface
Default IP Address:
Open a browser and enter:
http://192.168.2.1
Login Credentials:
Username:
adminPassword: (printed on the router label)
⚠️ On first login, you may be prompted to change the password.
3. Configuring APN Settings for Telnyx
Navigate to: Network > Interfaces
Edit Mobile Interface:
Click the pencil icon next to
mob1s1a1(mobile interface).Uncheck Auto APN.
Enter the following:
APN:
data00.telnyxUsername/Password: leave blank unless instructed.
Save Changes:
Click Save & Apply.
4. Verifying Connectivity
Check Status:
Go to
Status > Network Information.Confirm:
Connected status
Assigned IP address
Signal strength is within usable range
5. Configuring Auto-Reboot for Network Recovery (Recommended)
To ensure the modem recovers from service interruptions or poor network connectivity, configure the auto-reboot watchdog feature:
Navigate to: System > Auto Reboot
Enable Watchdog Monitoring:
Enable Auto Reboot.
Set Reboot Conditions:
Select Ping Reboot
Enter reliable targets like
8.8.8.8and1.1.1.1
Set Ping Interval and Retry Count:
E.g., ping every 60 seconds, reboot after 3 failures
Optional: Enable Scheduled Reboot (e.g., daily at 3 AM)
Apply Settings:
Click Save & Apply
🔁 This helps the modem recover automatically from outages without manual intervention—especially critical for remote or unattended deployments.
6. Optional: Teltonika RMS for Centralized Fleet Management
If you’re deploying many Teltonika routers with Telnyx SIMs, using Teltonika RMS (Remote Management System) is highly recommended.
What is RMS?
A cloud-based management platform by Teltonika that enables:
Real-time monitoring of devices and SIMs
Remote firmware/configuration updates
Command-line access for remote diagnostics
Batch operations (e.g., set auto-reboot across 100+ routers)
VPN tunnel setup and firewall configurations
Alerts and logs for connection drops or reboot events
Benefits for Telnyx SIM Users:
Central dashboard to track usage, signal, uptime
Minimize truck rolls with remote troubleshooting
Set up auto-reboot and APN settings for all routers
Monitor health of every modem in the field with automated alerts
How to Start:
Sign up at rms.teltonika-networks.com
Register each device using the unique RMS code found in the web UI (
System > RMS)Apply configuration templates or execute remote CLI scripts
💡 Telnyx customers managing LTE modems at scale will benefit immensely from RMS observability, bulk configuration, and failover automation.
7. Firmware & Security
Update Firmware:
System > Firmware– check for latest updatesFirewall: Customize via
Network > FirewallVPN Support: Available under
VPN(OpenVPN, WireGuard, IPsec)
8. Backing Up Configuration
Go to
System > BackupClick Generate and download the backup for disaster recovery
9. Troubleshooting Tips
No Internet:
Ensure SIM is active and APN is correct
Confirm signal reception is sufficient
Verify auto-reboot is configured in case of prolonged disconnection
Weak Signal:
Move router to a better location
Use external antennas to improve signal gain
