Why did the mobile phone receive the verification code without prompting?

The reason why the mobile phone received the verification code without prompting:

1. The user's own mobile phone number is blocked by the operator.

2. Blacklist settings such as SMS security software.

3, mobile phone internal browser privacy settings.

4. The number of short messages sent by your mobile phone exceeds the maximum limit of one day.

5, network wireless network, communication and other delays.

Solution:

1. You need to contact the operator to solve this problem.

2. Check the settings of SMS blacklist, click "Menu" to enter "Harassment Interception", and click "Settings" to check the interception mode and whether there are numbers in the black and white list that are not allowed to reach SMS.

3. Reset the security level of the browser or turn off the "Block third-party Cookie" setting in the browser.

Please wait patiently or try again after the countdown is completed.
