Created attachment 136518 Modem and Network Manager Debug Logs

Good Day,

I am using NM and MM on my Raspberry Pi 3 (debian:stretch) with a "Industrial" Huawei M2M 3G Modem (MS2131I-8).

I have come across an issue where the modem does not connect at what appears to be the last stage i.e. establishing the ppp interface. However if I physically remove the modem and re-plug the modem (sometimes a few times) it eventually connects (and sometimes disconnects awhile later). Please could you advise what the issue could be?

I have attached both NM and MM debug logs. I started MM and then NM.

Thanks
