What does it mean to change the password of Minke Micro-service mobile phone and always show that it has not been received?

The password change of the micro-service mobile phone of Minke always shows that it has not been received, which means that the short message cannot be received. The reasons are as follows:

1. The security level of the internal browser of the mobile phone is too high, or the setting of shielding "third-party cookies and website data" is set.

2. The number of SMS messages sent by mobile phones exceeds the upper limit of the day. In order to avoid SMS bombing and waste of resources, some mobile phones are set to send up to 1 SMS messages per mobile phone number every day.

3. There is a delay in communication in wireless network. Due to network or regional problems, the authentication information sent by the server may be delayed.
