• Message has been processed and sent to the next instance, i.e., a mobile operator with request acknowledgment from their platform. The delivery report has not yet been received and is awaited, so the status is still pending.

• Message has been processed and sent to the next instance, i.e., mobile operator.

• Message has been accepted and processed, and it`s ready to be sent to the next instance, i.e., operator.

• Message has been sent to the operator, whereas the request was rejected, or a delivery report with status REJECTED was reverted.

• Message has been received, but the network is either out of our coverage or is not set up on your account. Your Account Manager can inform you about the coverage status or set up the network in question.

• Message has been received but has been rejected as the number is not recognized due to an incorrect number prefix or number length. This information is different for each network and is regularly updated.

• Message has been received and rejected due to the user being subscribed to DND (Do Not Disturb) services, disabling any service traffic to their number.

• Your account is set to accept only registered sender IDs, and the sender ID defined in the request has not been registered on your account.

• Your account is out of credits for further submission. Top up your account. For further assistance in topping up or applying for an online account top-up service, you may contact your Account Manager.

• The sender ID has been blocklisted on your account via Infobip web interface. Remove the blocklist on your account or contact Support for further assistance.

• The destination number has been blocklisted either at the operator request or on your account via web interface, please remove the blocklist on your account via Infobip web interface or contact Support for more information.

• The request has been rejected due to an expected system error. Retry the submission or contact our technical support team for more details.

• The request has been rejected due to a duplicate message ID specified in the submit request; the message IDs should be a unique value. For more information, refer to SMS on the Infobip API Developer Hub.

• Message has been received and our system detected the message was formatted incorrectly because of either an invalid ESM class parameter (fully featured binary message API method) or an inaccurate amount of characters when using esmclass:64 (UDH). For more information, visit the articles below or contact our Support team for clarification.

• The request has been received, however, the destination is invalid—the number prefix is not correct as it does not match a valid number prefix by any mobile operator. Number length is also taken into consideration when verifying number validity.

• The URL of the audio file is invalid and could not be read properly.

• The language submitted within the request is not supported and request couldn’t be processed correctly.

• Native to Voice services, this status is returned in case there is no text sent in your Voice message request.

• The status occurs when in a Push API call in object TO defined filter which doesn’t resolve any pushRegistrationIds as destinations for Push delivery. Field to is used to query the message recipient segment. For example, you can try to target according to a “tag” which doesn’t exist at any of instances of the requested ApplicationCode; it will return no destinations as we couldn’t find anything that would satisfy the requested conditions in our database. In another example, you may want to target all application instances (devices) with the Android OS. In this case, you have to use CloudType: GCM and API internally will resolve all destinations and will send the message to all Android devices linked to the requested ApplicationCode. You can also check your valid registrations by using filtering in our web interface. You can more information about User Data at our SDK pages: iOS and Android.

• The status occurs when an invalid or non-existent ApplicationCode is used in the field from in a Push API call. Each application profile has its own unique ApplicationCode. ApplicationCode is used in SDK as a key identifier for the Application installed on an end user’s device able to communicate with our platform. For the paired device + installed app, pushRegistrationId is issued and it is uniquely linked to ApplicationCode. You should be able to get all available applications or check the configuration.
