It sees the network, LED4 is on solid, but AT+CNUM still returns +CME ERROR: 0.

Is my SIM missing something? Or, what am I missing?

That was it! Thanks. That page had failed to provide a cert when I started. No firmware was the cause, apparently. It went through fine this time, so I upgraded certs and it now connects.

Hello,

Thanks for providing your log file. Good to see that both modem and application is up to date. The error that is causing this is due to:

asset_tracker: Socket error: POLLHUP

Did you power cycle the board after the update?

Also, have you updated your certificates on your board following this guide? It not, can you please try this as well. Note that it is important to carefully read the steps before starting.

Let me know how that works for you.

Kind regards,
Øyvind
