Thanks for the heads-up on this. I wasn’t aware of it.

The DeniedRegistration thing is part of the GSM standards. If the SIM repeatedly can’t connect to the network, the modem itself backs off and won’t try for an exponential delay.

There is a low-level AT command that can clear this, but normally best to wait for the network to recover.

Regards, Mark.

P.S. Also worth double-checking you still have balance on the account.

Now that it's back on my home wifi I can see the gps is happy (locked on 10 sats) and the simcom has signal but is in DeniedRegistration state... Looking at https://status.hologram.io/ I see they had an outage today.
