I launched the Super QQ+ SMS version (mobile phone binding) last year, and the Super QQ has risen to 6. If the mobile phone binding is removed, is it 1.8 times to upgrade without logging in?

I don't think so. I also have an annual fee plus SMS version of Super Q, and I don't log in almost every day. Personally, I think it doesn't matter if I don't log in every day, but the SMS version of Super Q is bound to move online. If you delete the binding, you will not be able to move it online. So if you lose the binding, you have to log in for 2 hours every day to accelerate to 1.8.
