"Unfortunately, NetworkSystemProvider has stopped" Error, what do I do?

[AC Question]

So my Sprint Note 4 got an update on Wednesday night and the next morning I was getting this error message. It pops up every 1-3 minutes, and as if that is not annoying enough, I am unable to make calls now due to it. Every call I make fails outright or disconnects during followed immediately by that error. I did not have any issues making calls prior to this.

I put my phone in safemode, factory reset it, cleared the cache partition, and had the software reflashed at Best Buy. Even with the phone completely default the error and issues since the error started persists.

I even tried switching to another Note 4 (we used to have two on our account but my friend switched to an iPhone leaving the second Note 4 free). I got my service switched over to the other Note 4 and everything was going fine... but like an ***** I didn't turn off autoupdates and the second one received the update as well. At first I thought it would be fine, but then the error started up on it too and I now have two phones that are useless as phones.

Does anyone have any ideas? Or can at least tell me what this NetworkSystemProvider crap is and what is going on?

I have a Note 4, on Sprint, and have begun seeing this same problem after an OTA update last week. It is extremely frustrating.

Chiming in to say I'm getting this as well as of 11/13/16. Phone randomly rebooted in my pocket (heard the Sprint chime), when it finished rebooting, the phone was borked. No facebook messanger app installed (other thread links issue to that app). Tried removing sprint zone updates, no good.
