No connection to the car

Updated October 14, 2026

The security system connects over the mobile network (LTE / GPRS / SMS). If there is no connection, the app shows a yellow Connection lost bar below the header, the signal icon is crossed out , and commands are answered with No connection. Try again later. The screen keeps showing the car's last known state.

The security functions keep working: the security system records events and sends them as soon as the connection is restored.

To restore the connection:

1. Check the balance of the security system's SIM card.
2. Check the coverage. There may be no network in an underground garage, a tunnel or outside the city. Drive into an area with coverage and wait a few minutes.
3. Check the internet on your phone. The app needs to be online too. Pull the main screen down to refresh the data.
4. Check the car battery. If the battery is flat, the security system may turn off. You can see the voltage in the Battery field.

Second SIM card

The security system supports Dual-SIM, so you can use SIM cards from two carriers for a more stable connection.

If there is no connection for more than a day, contact the security system installer or our support team: +380 44 365 0 911, support@gardix.systems.
