How to Disable Roaming

How to Disable Roaming

This guide explains how to disable roaming functionality on your cellular gateways using AT commands through the web interface. This method is applicable to the device with RobustOS and RobustOS Pro.

Background

While there is no dedicated toggle button for disabling roaming in the Web UI, this can be achieved by configuring an AT command to run on boot.

Prerequisites

  1. Access to the cellular gateway's web interface
  2. Administrator credentials
  3. Basic knowledge of navigating web UI settings

Steps

1. Access the Web Interface

  1. Open your web browser
  2. Navigate to your cellular gateway's management interface
  3. Log in with your administrator credentials

2. Navigate to Cellular Settings

  1. Go to Interface
  2. Select Cellular
  3. Click on SIM1 settings

3. Configure AT Command

  1. Locate the "Extra AT Cmd" field
  2. Enter the following command exactly as shown:
AT+QCFG="roamservice",1

4. Save Changes

  1. Click Submit and Save & Apply (checkmark icon on top right).
  2. Wait for the settings to be applied

Verification

  1. The AT command will now run automatically on boot
  2. Roaming will be disabled for your cellular connection

Troubleshooting

If the command doesn't seem to take effect:
  1. Verify the command syntax is exactly as shown
  2. Ensure there are no extra spaces or special characters
  3. Try rebooting the gateway
  4. Check the system logs for any error messages

Notes

  1. This configuration will persist across reboots
  2. The setting affects only SIM1 if you have a dual-SIM gateway
  3. Some carriers may have specific requirements or restrictions regarding roaming settings
