Many satcom operators geoblock their terminals in regions where they do not have license to transmit. This is trivial as both modem and hub/nms/noc will have the gps data from the equipment. Most governments don't care enough to do anything about illegal transmitting, but some, like the Indian coast guard, has been known to board ships and write out fines and cause a ton of paper work for ships sailing with transmitting satcom equipment. And often they don't know how to determine if the equipment is transmitting or not, so it's safest for the crew to just turn it off when within Indian territorial waters even if the satcom provider automatically mutes equipment.
