If this should occur, please consider the following:
- Ensure the cellular antenna is securely attached to the VBOX Sigma.
- Make sure that the unit is connected to the internet either via the internal GSM modem or an external Wi-Fi hotspot.
- If using the internal 4G modem with a SIM card, ensure that you haven't exceeded your data allowance.
- Ensure that you have an active subscription with your NTRIP provider.
