Delivery Receipts and Response Codes

OpenMarket successfully sent the message to the mobile operator.

In some situations the mobile operator will not return any further update than this receipt (e.g. for a message sent using a US landline). If this is your final delivery receipt, treat this as a "successful" delivery.

Retryable: n/a

OpenMarket has accepted and processed your message request but has yet to forward it to the mobile operator.

You will only receive this receipt code in the response to a Get Message Status request. You are very unlikely to see this code unless you rapidly perform the request after submitting the message.

This code is not returned for final delivery receipts.

Retryable: n/a

OpenMarket has sent the message to the mobile operator. We are still waiting for a response.

You will only receive this receipt code in the response to a Get Message Status request. This code is not returned for final delivery receipts.

Retryable: n/a

The mobile operator successfully delivered the message to the end user.

Retryable: n/a

Your request specified a value for mobileOperatorId that is not one of the pre-defined IDs.

For a list of the valid IDs, see Mobile Operator IDs.

Retryable: no

OpenMarket performed an operator lookup for the end user's number and found that the number is not registered with any mobile operators.

Note that the region in which we perform the lookup will depend on your messaging use cases — if you are only provisioned for US and Canadian messaging then we will only perform an operator lookup with the US and Canadian mobile operators. Therefore, requests to mobile numbers based in other destinations (like the UK) would come back with this error.

Retryable: no

The carrier ID you provided is not associated with a carrier our system supports. Verify from MO SMS if possible. Please contact OpenMarket support for further information

Retryable: no

Double-check the destination address to make sure it contains only numbers.

Retryable: no

Mobile operators send us this delivery receipt for a variety of reasons. Unfortunately, these different error conditions are mixed between ones you could retry or not, based on the operator's own use of this code.

If you are messaging anywhere outside of the US, we cannot refine the issue further, other than knowing that the message was sent using the right encoding to the correct mobile operator.

OpenMarket has received more information from the US mobile operators. When messaging a US end user, the possible reasons can be one of:

• Any operator: The mobile number is not on the mobile operator's network.
• Any operator: The mobile number has been deactivated. Check the Deact reports on Customer Center.
• T-Mobile and MetroPCS: The phone number belongs to a prepaid user who does not have enough credit to receive an SMS.
• T-Mobile only: The end user is not provisioned to receive SMS from all short codes (or from specific short codes).
• T-Mobile only: The end user is on a MVNO connected via T-Mobile. T-Mobile does not deliver SMS messages from short codes to end users on MVNOs.
• AT&T US: There are several possible causes for the error:
  • The phone number belongs to a prepaid user who does not have enough credit to receive an SMS.
  • The phone number is not provisioned for SMS.
  • The phone number could be blocked due to a spam complaint.

In general, mobile operators do not want SMS senders to retry MT messages that have failed with error code 351. However, given the range of different possible root causes, we think it is reasonable to retry some of these messages.

Here is our suggested behavior for US messaging:

• Perform a number preview request to confirm that the number is on the mobile operator's network.
• Check the Deact reports to ensure the number is still live
• For T-Mobile specifically, you could retry the message using a US VMN or other number
• If desired, retry the message using a slow retry method; for example, retrying once every day for up to 7 days

Retryable: conditional

OpenMarket did not forward the message to the mobile operator. This is because the message required multiple SMS parts, and your request did not specify to create a multipart or truncated message. This is set using mlc in your request. By default, mlc is set to reject messages; to change this behavior add mlc with either the option truncate or segment (creates a multipart message).

Retryable: no

The mobile operator rejected the message with an invalid MT source address error. Contact your account manager to determine if your MT source address should be supported by the end user's mobile operator.

Retryable: no

Possible causes might be:

• Your message originator is currently blocked from sending messages.
• You tried to use a TON 1 or TON 3 MT source address that is not provisioned on your account.
• There is a mismatch between the MT source address TON and the MT address. Verify that you are sending MTs from short codes with TON set to 3 and sending MTs from VMNs with TON set to 1.

Talk to your OpenMarket account manager if you are unsure why you received this error.

Retryable: no

The message was blocked by AT&T because the TPS (transactions per second) limit on your messaging campaign has been exceeded.

Retryable: Yes you can try re-sending the message, though delivery cannot be guaranteed. You may still encounter the TPS limit.

The message was blocked by T-Mobile because the daily volume limit for your brand has been exceeded. You cannot resend the message until the next day.

Retryable: no

Retryable: no

The message was blocked by AT&T's spam filter.

Please contact your OpenMarket account manager if you want to discuss changing this limit.

Retryable: no

The end user's number has a country code that is from a region of the world that you are not provisioned to reach. For example, if you exclusively message in the US or CA, you will not be provisioned for messaging end users who reside in other regions. If you'd like extend your messaging to reach end users globally, please contact your OpenMarket account manager.

Retryable: no

OpenMarket could not determine either the message originator to use or the interaction type for your message. This error occurs if you do not include one or more of: source address, ton, or interaction, and you have:

• Multiple short codes provisioned for the same country
• Both a number and an alphanumeric string available for a region but have not specified the interaction type you'd like.

OpenMarket will not arbitrarily pick values to use. For more information see Automated Originator Selection and Message originators.

Retryable: no

This error occurs if your message request does not include a source address (e.g. your message originator) and there is no pre-provisioned address suitable for messaging the end user.

For example, this could occur if your normal messaging is to the UK only and you message another international number without having a default originator set for messaging to that region (or globally).

Contact your OpenMarket account manager if you want to add a default originator for messaging to any new regions.

Retryable: no

This error can occur if you set interaction to two-way. In some countries, OpenMarket supports one-way only.

See our SMS Global Coverage Map.

Retryable: no

Your request specified an interaction and message originator that are incompatible. For example, you will receive this error if you specify "two-way" but your originator is an alphanumeric string, like "ACME123".

Retryable: no

This error can occur when sending a WAP Push to a US or Canadian end user. Not all mobile operators in this region support or allow WAP Push messages.

We suggest resending the URL as plain text in an SMS message, as most smartphones will turn this into a hyperlink.

Retryable: no

The message request had set interaction to two-way, however, your business account is not provisioned for global two-way messaging. The provisioning options are:

• US and Canada messaging
• Global one-way (all regions aside from the US and Canada)
• Global two-way (all regions aside from the US and Canada)

Note that you do not need to set a value for interaction for US and Canada messaging.

Contact your OpenMarket account manager if you need global two-way messaging provisioned.

Retryable: no

This code can be returned in a delivery receipt for an MT originating from a North American, SMS-enabled toll-free number or an SMS-enabled landline number. Messaging can resume to the end user when he or she opts back in to your content.

Retryable: no

The message was blocked by a spam filter and will not be delivered to the end user's handset. If you believe your message was falsely identified as spam, please submit a ticket to OpenMarket Support.

Retryable: no

Communication to the end user failed, despite the end user's account being provisioned for SMS and the handset SMS-capable. This is typically a temporary failure -- for instance, the handset might be turned off or without coverage.

Retryable: yes

Communication to the end user failed to due to either the handset not being SMS-capable or not provisioned for SMS.

Retryable: no

The destination mobile operator currently is unable to deliver SMS messages due to high traffic.

Retryable: yes

The mobile operator network infrascture has returned an error. This might be at either the Mobile Switching Server (MSC), Short Message Service Center (SMSC), or Home Location Register (HLR).

Retryable: yes

The mobile operator is explicitly rejecting the request, possibly on the end user's behalf -- for example, the end user's handset might be set to Do Not Disturb (DND) or has been opted out of receiving service traffic.

Retryable: yes

The mobile operator returned a generic error for an unexpected failure in message delivery.

Retryable: no

The mobile operator accepted the message, but has informed us that message delivery failed. They do not want retries of the same message.

Unfortunately this message may be returned for a variety of reasons, which the mobile operator has decided not to distinguish between.

Retryable: no

OpenMarket and/or the mobile operator attempted to deliver the message to the end user for the duration of the MT validity period. However, the message never reached the end user's handset.

You can set a validity period in the MT message request. If you did not supply a validity period in the MT, MT delivery is generally retried for up to three days before expiring the MT.

Retryable: yes

When OpenMarket sends a message to a mobile operator, we expect to receive an asynchronous reply confirming that the message was received. If we don't receive a response (and after using our retry strategy) then we will return this error to you.

It is possible that the end user may have received one or more of the same message (or not received the message at all).

You can receive this receipt code in the response to a Get Message Status request. However, this code is not returned for final delivery receipts.

Retryable: n/a

This means that we have not received delivery receipt data for at least one part of a multipart message.

For example, you will get this code if one message part has been successfully delivered but we do not have a receipt for the second message part. However, if any message part has failed delivery, then code 830 is returned.

You can receive this receipt code in the response to a Get Message Status request. However, this code is not returned for final delivery receipts.

Retryable: n/a

OpenMarket was unable to finish processing the request; therefore, your message was not sent. You can retry your request in intervals of 10 seconds or more. If you continue to receive this error, contact OpenMarket Support.
