Instagram asked for a 6 digit code sent to either WhatsApp or to my Phone Number (messages app).
After trying for a while, I still couldn't receive the code from either. How can I get the code?

My problem is now I can't access to my Instagram because I didnt receive the code sent by Instagram.
Without the code, I cannot access to my Instagram.
Does anyone know how to fix the problem and get the code?

Above situation is actually by my son...
anybody who know or experience, kindly assist or share .. thank you.
