what's airplane mode ? I thought you couldn't use a cell phone on a plane....
Airplane mode disables the antenna(s) on your phone and stops transmissions related to your cell signal and WiFi access (if your phone is capable of that), allowing you to safely and legally use it on an airplane during the time when electronic devices can be used in-flight.
I always have airplane mode even after pulling battery, three times. can not seem to disable AP mode
You will need to go into Settings > Wireless & networks and then uncheck the box next to Airplane Mode to disable it. It will not automatically reset when you restart the phone.
