Device won't connect to cellular network

If you've just tried activating your device but the Time since last successful registration is not a few seconds or a minute ago, then check the following:

• Antenna: Ensure the external antenna is properly connected (if your device has an external SMA connector)

• SIM Status: Verify that SIM Status shows as "Ready".

  • If not, verify that the SIM Card was inserted properly - refer to IoT Pro SIM Card Installation.

• Network Settings:

  • APN: iot.1nce.net (if your device was shipped with a SIM Card) or check for the APN with your network operator

    • This should be left empty if unknown or if network roaming from one operator to another is needed

  • Network Operator Code: Get the network operator code using an AI tool or check here and enter the MCC followed by MNC

    • Example: Melita (Malta) has MCC 278 and MNC 77, so enter: 27877

    • This should be left empty if unknown or if network roaming from one operator to another is needed

  • Band: 20 (most common for EU networks) - Get the Network Band using an AI tool and confirm with the network operator if necessary.

    • All should be selected if unknown or if network roaming from one operator to another is needed

• Network Coverage: Verify your network operator has 4G LTE CAT-1 or NB-IoT coverage in your area (depending on your device type)

Messages aren't sending but Network is Connected

If you've activated your device and the Pending Messages count remains high or Sending Status shows "Send Failing", follow these steps:

1. Verify Network Settings - Confirm your Network Settings are correct (see section above)

2. Activate the Device - Activate and wait for it to register with the network

3. Check Registration Status - After reconnecting, verify that Time since last successful registration shows only a few seconds or up to one minute ago. If the time is longer, see section above.

4. Test Message Sending - Press Send Message, then reconnect to check if Pending Messages has decreased or cleared.

If Pending Messages count remains high, this indicates the device cannot communicate with our server. Contact your network operator to confirm they have whitelisted the following:

• Protocol: UDP

• IP Address: 57.129.34.12

• Port: 17062

Some network operators block UDP traffic or specific IP addresses by default, which prevents the device from sending data.

Message delivery is slow or unreliable

If your device is activated and can send some messages, but network performance is poor (such as slow responses or delayed alerts), try adjusting these settings. Press Activate after having adjusted the Advanced Message Sequence and returned back to the main view.
