Thanks! That made all the difference! OK, I should have just taken the advice wrt these settings before. Why do they enable this by default? It looks pretty broken. "volte_disable" was set to 0. I guess that explains that "ims" thing? So I never got around to the MBIM testing. But given these results, I assume I would have had similar issues there. This appears to be a Quectel specific configuration problem. Well, back to testing MM without all the modem imposed confusion.
