In a previous article, "gatt" said:
I just use a cell-phone. Either text message them, or just call them. If
they hear my voice, I can tell them there's a delay. If all they hear is
noise, I'm fifteen minutes out.

I don't get a signal on my cell phone at altitude, and I've always been
too busy when I'm down low to check.

should be hard to understand.
