Grace, et al;
Radio waves do not travel well under water. They are reflected off of solid objects (walls, floor) and are dissipated in a very short time.
Submarines communicate with very low frequency waves. The antennas that pick up these signals are miles long.
So, the warning system won't work. That is why the buddy is so important, so if you do get stuck, they can help.
Wish I could give you more hope. Please remember that we are all given Free Will by our Maker.
