    Note: These devices do not come with a SIM card. Some functions, like acting as a serial server open to the internet require a SIM card with a publicly routable IP address. Most SIM cards do not have this feature by default, though some carriers can change regular SIM card account settings to give you the option. Telstra cards usually use the telstra.internet APN. You'll want your account to have the "GPTEXB3" option, and use the telstra.extranet APN.
