I want to send data from cloud server to a device in which hologram SIM is inserted.
There are two options to send data to it from dashboard, SIM or Cloud data.
I understand sending data through SMS but don’t understand Cloud data function.
I read this page. So must the device be a server?
I’m poor at communication system, but as long as I know, a server must have a static IP. Does hologram offer a static IP?
