Lanzhou Bank shows that the SMS sending service is abnormal.

According to Lanzhou Bank, the reasons for the abnormal SMS sending service are network problems, wrong mobile phone number and limited SMS function.

1. Network problem: SMS cannot be sent normally due to network failure or network congestion.

2. Wrong mobile phone number: the entered mobile phone number is wrong or incomplete, which will lead to the failure of SMS sending.

3. Short message function of mobile phone is limited: the mobile phone is equipped with short message interception function or has met the short message interception conditions, so it cannot receive short messages sent by banks.
