Use In-Flight Wireless When iPhone Airplane Mode is Enabled
You can selectively enable WiFi access while your iPhone is in Airplane Mode, meaning you can use a flights wireless internet service without the cell phone itself being turned on. This is really handy since many flights are starting to have inflight wireless access, but in much of the world cellular use on airplanes is banned.
Here is how this works:
Enable the feature within Settings app of iOS like so: Tap on Airplane mode to enable that as usual, then then tap onto Wi-Fi mode to enable that. Next, tap to join the wireless network.
You’ll be on a wi-fi network while AirPlane still maintains it’s ability to prevent the cellular service from activating.
Always check with a flight attendant before attempting this, just to be sure you are in compliance with your air carrier.
You can actually use this wi-fi with airplane trick on any iPhone or iPad that is cellular enabled, and if you want to you can turn on bluetooth with airplane mode enabled as well.
This cool tip idea comes from FinerThingsInIPhone, but if you have ever flown on a plane with in-flight wi-fi you know this is useful to nearly everyone out there. Enjoy.
