I use sleep mode on iOS and that will block basically everything. Emergency alerts will still go through, which is important to me as I live in a very wildfire prone area. My mom is white listed as well for family emergencies. Sleep mode will also allow a call to ring if they call twice back to back and that has allowed my brother to reach me in the past during an emergency. I’d be too nervous to completely cut data and cell service.

Got 9 in one day. If they include a name it’s never mine
