6.1.2. GSR Without Coverage, or Poor Coverage.

Go to ‘Troubleshooting Guide’

Go to ‘Hardware Index’

The coverage LED does not turn on or indicates poor coverage.

*Note: If you need to change the SIM card of the GSR, it is necessary to turn off the GSR using the power button both to remove the installed SIM and to insert the new SIM. Once the change is made, you can turn the GSR back on by pressing the power button.

1º- Check the SIM card.

• With the GSR powered off, remove the SIM card and check for any damage. Reinsert it in the correct position. (see upper image)

• If the SIM is damaged, it may be causing malfunction. When inserting the SIM into the GSR’s SLOT, it should make a “CLICK” when pressed.

• If the SIM card shows signs of damage or wear, contact Support for replacement the SIM.

2º- Check the mobile antenna.

• Ensure that the connected antenna is for mobile network and not for WIFI.
• Ensure that the antenna is connected to the connector for mobile network (right connector).
• Check that it is properly screwed in and the connector is in good condition.
• Check that the antenna cable is not cut, does not have partial cuts, deformations, or abrasions.
• Check for any devices or installations near the antenna cable that could cause electrical noise or interference.
• Move the antenna to a better position for better coverage. If the antenna is inside a box or near devices that generate electrical noise, it could result in poor coverage.
• If necessary, it is recommended to take the GSR outside the installation (operating only on battery) to check if the issue is with coverage within the installation.
• If the antenna has cuts or deformation, is of low gain, or the cable is short, the antenna must be replaced with a new or suitable one for the installation. Contact Support for replacement the antenna.

3º- Make an incoming phone call to the GSR.

• Call the line number corresponding to the installed SIM card to check if it gives a tone or if the operator provides any message indicating a possible issue with the line or operator.

4º- Verify the status of services with the SIM card operator.

• Check that the SIM card is activated and the services are contracted on the operator’s platform.

5º- Check if the PIN is disabled.

• The SIM card might have the option to request a PIN to connect to the network. To check, disconnect the GSR, remove the SIM card, insert it into an unlocked mobile phone, and from settings, disable the option to request a PIN.

6º- Test the SIM card in another device (GSR or another GSM) or in an unlocked mobile phone.

• This test will verify if the SIM has the option to request a PIN disabled and see if the SIM’s behavior in another device is the same or different from in the installed GSR.

7º- If a problem with the line or the services activated on it by the operator is confirmed, contact Support to check, activate, or replace the SIM.
