Why can't my online banking phone receive the verification code?

Hello, do you use a debit card or a credit card? Is your online banking registered at the counter? If so, and I didn't get it, I think you may be using the online payment function. This function is independent of online banking. You need to turn on your mobile phone to receive the verification code for online payment. You can call customer service or open online banking. Personal bank debit cards need to be opened at the counter, and credit cards can only be opened by calling customer service. You can ask me if you don't understand.
