If the mobile phone dynamic password cannot be received, there may be many reasons:

1) Restart the phone to solve the problem.

2) If the mobile phone’s SMS box is full, clear the SMS box.

3) If there is a problem with the mobile phone, try changing the SIM card to another mobile phone (you need to put it on the other mobile phone before sending the text message)

4) If the SIM data is full, go to the business hall deal with.

5) If your mobile phone has a blocking program, set it to not block or turn off the blocking program or add 95511 to the whitelist of users. (iPhone: Settings-Information-Blacklist, just unblock)

If the effect is still not satisfactory, it is recommended to directly call the credit card’s 24-hour customer service hotline 95511 and press No. 2 to be transferred to a customer service specialist for consultation. .
