It’s not just your phone sending out strong signals, it can be your laptop, tablet, and portable game consoles too. That’s the reason for all of this airplane mode stuff. Way back in 1991, the Federal Communications Commission (FCC), which is an agency in the United States, banned phone calls on planes, as the radio frequencies emitted by old school cell phones with big antennas and other electronic devices could interfere with an airplane’s equipment, including navigation and communication systems. But, is it really necessary? –There have certainly been times where we’ve forgotten to turn airplane mode on while on a flight, and nothing bad happened, at least.
If you don’t fly frequently, chances are you don’t use it a lot. Wi-Fi and Bluetooth shut off, but for those two, you can turn them back on manually. You won’t be able to make phone calls or send text messages. When you activate airplane mode, it basically blocks all signal transmission from your device, particularly cellular connections. We are sure you all know, that when you go to the quick settings menu on your phone, there’s an airplane icon.
