1. A method of communicating between an Internet of Things device and a remote computer system, the method comprising:
receiving in the Internet of Things device a secured data package from a mobile communication device via a close range communication circuit;
decrypting in the Internet of Things device the secured data package, using a cryptographic key stored securely in the Internet of Things device;
extracting in the Internet of Things device from the secured data package an identifier of a back-end system associated with the remote computer system and storing the identifier of the back-end system in the Internet of Things device;
transmitting via the close range communication circuit an upload data message for the remote computer system from the Internet of Things device to the mobile communication device, for forwarding to the remote computer system, the upload data message including the identifier of the back-end system stored in the Internet of Things device;
responsive to the upload data message, transmitting a download data message for the Internet of Things device from the remote computer system to the mobile communication device, for forwarding to the Internet of Things device; and
receiving in the Internet of Things device the download data message from the remote computer system, as forwarded by the mobile communication device via the close range communication device.
