Nano-SIM card

The customizable version of type 3677 is equipped with a nano-SIM card slot instead of an integrated eSIM card. In such cases, the nano-SIM card provided by the customer is already installed and tested at the Proemion factory. Replacing the nano-SIM card in the field is not recommended and may void the warranty.

Potential connectivity loss with custom SIM card

The device cannot establish an online connection to the DataPlatform when using a customer-specific nano-SIM card with incorrect firewall settings at the SIM provider. IP addresses of the DataPlatform may change without prior notice.

  • Make sure that the SIM card provider is not using IP address based white-listing for any DataPlatform communication.
  • Make sure that - if white-listing is required - the corresponding DNS names are white-listed at the SIM provider's firewall.

Malfunction due to defective nano-SIM cards may occur.

  • Make sure that the specification of the selected nano-SIM card meets the environmental requirements of the device.
  • Ensure that the dimension of the selected nano-SIM corresponds to form factor 4FF.
