@rickkas7 did a nice post on using 3rd party SIMs-- this is what I used to get mine running smoothly:
Understood, although I was wondering if anyone had insight on this scenario from digging through the U-Blox AT commands in the past. I didn't see anything obvious from looking at the command list. I know @rickkas7 has posted some good info on using low-level modem commands but I haven't seen anything about this particular scenario.
To look at it from another angle, any idea where I can find the Cellular.ready() logic in the source code?
Thanks,
Mike
