LG G3- problems with last update

[Android Central Question]

Hy there,

Im experiecing weird behaviour with my G3, and I think it is due to last update.. So the problem is that my phone resets for 1000 of time during the day, and I get error message that says '' Sim card unvalible, please enter valid Sim card'' and then, reset, and that happens dosens of time during the day. Is there anyone else that is expericing this? Because Im not the only one, my sister got that problem few days ago.

Welcome to Android Central! Moved to the G3 forum. Does this happen in Safe Mode as well? https://support.t-mobile.com/docs/DOC-30130. Is the phone a carrier-specific variant, or an unlocked variant?
