          We can see some data usage from the SIM card…so it maybe it just needs a longer time before “Putting modem to sleep”?

            What is the APN name that US Cellular gave you use?  Is the SIM card activated?  Have you ever used that particular SIM card on another cellular device, like a tablet or phone?  Are you sure that t

                    There’s no easy way to tell your Mayfly sketch to  wait longer on initial startup, the instructions for that are buried deep in one of the supporting library files and not in the main sketch.
