Security controls also trigger problems. When the system detects unusual activity, it may restrict access. This leads to Blocked USSD Access Bank status and an ussd profile blocked message. Multiple wrong PIN attempts or long inactivity often cause this. Customers then face repeated access bank ussd error prompts until the block is lifted.
Registration errors create another layer of trouble. A Wrong phone number USSD setup means the system cannot recognise your requests. This results in ussd registration problems and common ussd code failure reasons. Many users assume the service is broken when the issue is simply an incorrect number linked to the account.
