Cant get nulls connect code

I’m trying to connect to nulls connect but it takes 1 hour + to get the code and when I get it, it says the code is incorrect. Is there another way to connect or any solutions?

Hi. I have experiences. Maybe this problem will be solved for you. It is possible that your mobile phone has little memory. And when you receive the code, you will face a problem. Memory. Bring it to normal. It’s not right…we have to wait for the leaders to get the answer

if you change null’s connect accounts frequently, the verification code will be temporarily frozen.

and what should I do about it?
