The end user’s operator has restrictions set on the account based on the tariff and the associated terms and conditions of the account.
The end user should contact their network operator, to either remove the restrictions in place, or change the contract to a tariff which permits the SMS MT services.
MSISDN is barred
The end user should contact their network operator, to either remove the restrictions in place. The MSISDN may be blacklisted or not permit certain SMS based transactions
End-user cannot be billed, or receive bills.
Certain End-users cannot be billed as they do not have an appropriate billing profile, or require age verification before services can be rendered. In such cases the end user should contact their network operator in order to manage the services which can be subscribed to.
End-user is not registered to the service
The End-user has not opted into the service being provided, and may be subject to local opt-in processes.
Rejected By operator
The operator may restrict services rendered to customers for a variety of reasons. The end-user should contact their network operator to understand the reason and resolve.
