If it is the same issue i've been having on my braveheart, mobile data stops working, there is workaround for it: https://forum.pine64.org/showthread.php?tid=12279
I have been trying this on mobian and arch and it does work.
However, i decided to try PostmarketOS phosh after not trying it for quite long time because it had bad battery life previously, now it does have pretty good battery life and its looking like this issue does not happen at all. I dont know what they did differently but what i noticed is that modem does not get redetected after sleep like it does on other distros that have the issue.
