ICBC Online Banking (Emergency) SMS Authentication Function

In your online banking function interface, there is a "security center" with SMS authentication function settings. I think it should be in there.

If you want to continue to use it, you should change your registered mobile phone number, but you'd better go to the counter to handle this. If this function is cancelled, the password card can only be used twice a day, and the amount of each time is below 500 yuan. Or go directly to the counter to handle the U shield, one in 68 yuan. There is no limit to the amount and number of times, which is relatively safe, so this authentication function is not needed. This function is also to ensure the security of online transactions, which is very troublesome when the mobile phone is not available.
