After looking into this further, I've noticed a consistent pattern where the events occur precisely every 23 minutes. This observation has raised suspicions that I might be experiencing the same issue detailed in this post: Boron LTE Disconnects. It's worth noting that the device operated smoothly for several weeks. Interestingly, when I deliberately initiated additional traffic after observing the offline/online events, it appeared to resolve the issue. I'm curious if anyone else encountered a similar issue and how it can be mitigated on a large scale, especially for devices that mostly remain idle, waiting for functions to be called and this issue appears to be random and sometimes fixes itself after some time. Not sure if load on the tower has something to do with this as well.
