Hello there,
I just got my new phantom pro 4 and I am doing the first time setup, using an I pad with wifi connection, I got stuck on the phone number verification. I put my phone mobile phone number (I'm from Italy) but it says number not valid, what should I do?
ps. I tried putting '' 0039 '' , '' +39 '' and only the phone number.

You just got it activated today, right?  Then a message popping up on the APP screen asking you to bind your mobile phone number to the aircraft?
Could you please help us confirm the following info which helps us figure it out for you?
The exact location you got the message on APP and the network IP address.
Then please export the log on your mobile phone here: DJI/dji.go.v4/log/CACHE/verphone. You can upload it to Dropbox and post the link here, thank you.

Hi.Thank you for your feedback. You can uninstall the DJI GO 4 app and reinstall it. If happened again,you can go outside and power your aircraft, after wait 2 minutes connect your phone and the remote controller, make sure your phone is connected to the network. Thank you.
