EESIM452 firmware updates automatically via mobile networks when the device has access to mobile data. In most cases, the APN must be correctly configured in the device settings to allow this.
A manual update can also be performed by downloading the firmware from our website. Before updating the firmware, please make sure to save both the configuration file and the User Database of your gate controller.
You can download the latest ESIM452 firmware from:
https://eldesalarms.com/gate-controller-esim320/#firmware
Please ensure you are logged in to our website to access the files. Once the firmware file is downloaded and saved to your PC, follow the steps below:
1. Power down the device.
2. Short-circuit (connect) the DEF pins.
3. Connect the device to your PC using a USB cable.

What are the prices of ELDES production?

How to change the SIM card?
To change the SIM card, first remove the PIN code from the card. Once the SIM card is replaced, test the new number by making a call. All users who previously accessed the gates should be able to use the new number, but they will need to call the updated phone number. If Cloud services are used then make sure to check if it will synchronize. You might need to configure the GPRS settings, such as the APN, according to your GSM operator’s guidelines.
