[Ovmsdev] Modem fails to connect

Need to see a ‘log level verbose’ output from the modem, for a minute or so. Also ‘simcom status’ output twice (again, a minute or so apart) so we can see what is changing.

The modem and mux layers are up, but it looks like the PPP connection cannot be established. You sure you have sufficient balance on the Hologram account? Not just a ‘live’ SIM, but enough balance to be able to establish a data circuit (if you are on a pay-as-you-go plan). Also, please triple-check the APN/user/pass setting and make sure it is ‘hologram’.

Regards, Mark.

Last active 5 days ago, but the simcom status shows it's hearing the cell tower just fine.  I'm on the .005 main software, v3.1 production hardware.
