new Pinephone issue possibly with modemmanager - or is this a hardware problem?

[Keith Ostertag]

I am not a developer, it was suggested to me that people on this list might be able to say with some authority whether my network connection problem is due to a hardware problem or a misconfiguration of modemmanger.

Using a Pinephone (original convergence package) running postmarketOS and sxmo.

The modem appears to be cycling around, shutting down every 30 seconds or so.

Here is a partial log from partial /var/log/modemmanager.err: https://dpaste.com/364H3K945

and a partial log from /var/log/eg25-manager.err: https://dpaste.com/DE6MZ4QKP

I am only wanting some confirmation that it seems to be a hardware problem before I issue an RMA for the pinephone, because I would not want to do so and later find out that the problem was a simple configuration mistake.

Thanks if you can help.
