Flight Mode really Flight mode?
So I've been a good citizen and have switched my Q to flight mode when on an airplane. However, about a month ago when i did this, I still received a text message while in flight mode. I thought this was weird and thought it might be a glitch and something do do with the broadcast nature of text messages.
However, this morning, after I landed in Chicago from Washington DC, first I received voicemail notification and then I had an incoming call. I was completely perplexed as I saw my signal strength indicator had an X through it. I thought maybe even if I answered the call, it would not go through, but the phone call went on as normal.
The way I believe cell towers works is that in order to have received that phone call today, my phone had to have registered on the cell tower first with an outgoing ping in order to receive the phone call. In this case, the "flight mode" on the phone might not be cutting off the radio but maybe just reducing the transmitting power? Either that or flight mode is a complete farce to keep stewardesses happy.
