Look on the map in the Advanced Unlocking page to see if the airport you want to fly at is a NFZ, chances are you will be fine and able to fly there with the GEO app. http://www.dji.com/flysafe/geo-system
Please view all the information on this webpage, you have to install 2.4.4 on your Android device and 1.07.00.48 on your aircraft. IOS will be available in the future.
Here are some instructions:

Instructions for GEO Beta app download onto  Android   device (currently only available for Android)

Uninstall the GO app from device: Go to settings, Applications, Application manager, find GO app and uninstall.
Installing 2.2.4 GEO Beta app: Go to DJI Geo webpage http://www.dji.com/flysafe/geo-system
Click on Android Beta Version APK, Agree to terms and it will then download
Go to  My Files, in Recent files click on the DJI app icon and it may say “Install Blocked” click on settings (if you get a different error then go to settings and scroll down to “Lock Screen and Security” Under Unknown sources slide the button to ON. Then go back to the DJI icon in My Files and then tap the icon and click agree and then the new 2.4.4 GEO Beta version app will open.

You also have to install the 1.7 firmware for your aircraft from the same DJI link. (only available for the P3 Pro/Advanced and Inspire.
When you get to the flying site, if it’s an Authorization Zone you can unlock providing a credit card or mobile phone number (using cell will send you a text message with a code)
You can also unlock from home ahead of time by using the map page and you can unlock up to 30 zones and they will be unlocked for 72 hours.  http://www.dji.com/flysafe/geo-system/unlock

Thank you very much for your response.

But is it a problem to keep 2.4.4 geo after, for all next flights ? and also with the Firmware 1.7.00.48... ?

and is it possible and easy to upgrade to next version... and downgrade when i need to fly in NFZ ?
or id it ridiculous ?

I don't wand to have bug with old firmware, especially for the gimbal as i've had in the past.
Thanks in advance.
