Why can't I always apply for the verification code of JD.COM White Strip mobile phone?

1, prompt: "Failed to obtain SMS verification code"

Please confirm whether the mobile phone number filled in is consistent with the reserved mobile phone number of the bank card. If they are inconsistent, it is recommended to replace the consistent mobile phone number and bank card. If it is consistent, I suggest trying it another time.

2. Prompt: "The number of SMS verification codes sent exceeds the upper limit, please try again tomorrow" or "The number of verification codes sent exceeds the upper limit"

Please try again after 24 hours, or click the Skip this task button to try another task directly. Please keep the mobile phone signal unblocked during verification, and don't click the verification button frequently, so as not to affect the activation probability. Thank you for your support to JD Finance.
