Have also noticed data just drops constantly. Not that there is low signal but 4g completely disappears, and then comes back, sometimes it takes a few minutes for it to come back but it's at the point where it is disrupting music and navigation.

If the signal is fine, please update to the latest system and try updating the latest MCU.
It seems that the SIM card does not support enough frequency bands and sometimes switches to 3G or 2G. However, if the operator no longer has 3G base stations, it will show no signal.
