I’m having the hardest time receiving the unlock code  text message from DJI when using the App . I’m currently on Guam my area code is 671 , I put my number in and I never receive any code . I’m I missing a step? Thanks for your help .  

Hi, there. Thank you for reaching out and we do apologize for the inconvenience. I will highly recommend to contact our designated department for further assistance at flysafe@dji.com. Thank you for your kind and understanding. Cheers!

Fyi.  I am never able to get a code texted to me either with a Senegalese mobile number.  I have to use my Google Voice based USA number for it to work...
