What is SMS check code?

It may be that you filled in a lot of transaction limits when binding your mobile phone. When your transaction amount is less than the number you fill in, you won't be notified by SMS, and you don't need verification code. There is also a situation in which the system is unstable and lags behind! Yesterday, so did i. After clicking the mobile phone verification code, there was no response for a long time. I clicked it several times in a row, and then I received several short messages about the verification code at once.

Hope to adopt
