I am using a soracom sim card which works in other various generic trackers. I want to try Teltonika as it appears to much better software and quality.
I also can’t paste a clean log because it says “new users can only post 2 links per post” even I put the log in a text snippet box. So I had to make it a link, sorry!
I had some success disabling NB-IOT and locking it to AT&T, but it hasn’t been perfect. I have yet to install it and see how it works in the field. It appears to be latching on a distant, NB-IOT signal that is barely usable in my correspondence with Soracom rather than the good AT&T one.
