Well because the obvious goal seems to prevent terrorist cells from effectively communicating, and Q told us years ago that the deep state has been known to use video game chat to pass on messages, my bet is that the only communication systems that will work will be 911 emergency calls and (hopefully) credit card processing.
If your cell phone says SOS where the signal bars belong, you have no service BUT you CAN still make 911 calls.
