This page will describes how to debug your beroNet LTE-device if something does not work as expected.

The following issues may occur because of inaccuracy in the manufacturing process of both connectors and SIM-card and can be mostly solved without opening a support ticket.
If the problems still persist after debugging, please contact our beroNet Support Team and we will help you as good as we can!

If you need immediate help by a technician you can schedule an On-Demand-Support or write a support ticket.

The SIM-Card is not recognised / does not register or loses registration

If your SIM-card is plugged in the corresponding connector, but the Status on the STATE-Page of the beroNet GUI is red, it means that the SIM was not able to register.

You can try the following procedures to identify or fix the issue.

Reseat the SIM-Card

The reason might be that the pins of the SIM-connector do not properly touch the contacts of the SIM-card, since the connector is very sensitive.

To test if this is the problem, you can simply reseat the SIM-Card and try again. When booting, the LTE modules will take a minute until it is started and registers the SIM to the network.

Use a Better SIM-Card Adapter

Open

Sometimes there are inaccuracies and manufacturing errors regarding the SIM-Card-Adapter that often comes with the SIM-Card.
Since our device needs a microSIM, you have to use a proper adapter to use a nanoSIM. The provided ones are often cheap and can lead to the described issue.

Make sure to use a high quality connector. These can be found on any online-shopping-website or phone-store.

Initial Activation of the SIM-Card

When you have a new SIM-Card, it may not initially work with the SBC. This is because some providers need to activate the SIM first over the network.
If this is the case, the SBC may take a few minutes to complete the first activation to the provider.

Test with Other Connectors

Try to switch the ports or connectors or modules to different slots to identify if the issue is connected to a faulty connector, the SIM-Card, or even the module itself.
If any of our parts is found to be source of the issue, please write a support ticket, so we can investigate further!

LED-Behaviour

Both the LTE module and the connector have LED’s to show the status of the registration or initialisation of the device to the network.

The LTE module in the device has its own red LED to show the status of the registration. This is different to the LED’s found on GSM and the front of the device.

The behaviour of the green LED in the front is the following:

• OFF - The module has not been initialised by the SBC.

• Blinking - The module is initialised and has is searching for a network or does not recognise the SIM

• ON - The SIM-Card has been connected to the network

The behaviour of the red LED on the module inside is the following:

• When the module is loaded and booted up, the red LED's start blinking until it is booted up.

• It will stay on when no SIM-Card is recognised.

• When it continues blinking, a SIM-Card has registered.

Distorted Audiostream / Interfering Static Noise

Reboot the Module / Gateway

If you experience distorted audio and distorted ringing when making a call on your LTE-Gateway, a restart is often enough to solve the problem.
The gateway sometimes needs a minute to initialise the LTE moddule and to start the telephony services, as well as register to the network.

If the distorted audio issue persists after several reboots, it might be a Hardware Issue. Please contact our support and we help you to solve the problem or to start the RMA-process.
