Mobile operators send a delivery receipt for a variety of reasons. Unfortunately, error conditions are mixed between messages you can retry sending 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.

However, possible reasons for the following mobile operators might be:

• Any operator: The mobile number is not on the mobile operator's network.
• Any operator: The mobile number has been deactivated. Check the number against the list of deactivated numbers in the Deactivated Phone Numbers Report in 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, it is reasonable to retry some of these messages. Suggested options are:

• Perform a number preview request to confirm that the number is on the mobile operator's network.
• Check the number against the list of deactivated numbers in the Deactivated Phone Numbers Report in Customer Center.
• For T-Mobile specifically, you could retry the message using a US VMN or other number.
• If needed, retry the message using a slow retry method—for example, retrying once every day for up to seven days.

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.

Short Message State: REJECTD

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.

The customer did not provide the MT source address, source address TON, and/or interaction, so the SMS application was not able to determine which source address and/or interaction value to apply to the MT. This can occur when more than one short code was provisioned for the same country as the country of the destination address. The application cannot arbitrarily choose one.

Short Message State: REJECTD

Retryable: No

The source address is not passed, and the SMS application determines there is no appropriate provisioned source address for the destination associated with the customer account.

Short Message State: REJECTD

Retryable: No

Interaction is provided in the submitted MT. The SMS application determined the country of the destination address did not support the interaction: one-way (33) or two-way (39). For example, a two-way interaction was passed for a destination in India, but OpenMarket does not have a two-way route for India.

Short Message State: REJECTD

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—for example, ACME123.

Retryable: No

A WAP push MT was submitted to a US or Canadian mobile subscriber, but the mobile operator either does not allow or does not support WAP Push. If you are trying to forward a URL to the end user using WAP Push, we suggest resending the URL as plain text in an SMS, as most smart phones will turn this into a hyperlink.

Short Message State: REJECTD

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).

Short Message State: EXPIRED

Retryable: Yes

This error is returned when OpenMarket was unable to process the finish processing the request. Your message was not sent. You can retry your request in intervals of 10 seconds or more, or contact OpenMarket Support if you continue to receive this error.

Short Message State: REJECTD

Retryable: Yes

The mobile operator is experiencing an outage or system error that should resolve itself shortly. Retry is attempted every 24 hours for a period of seven days. For T-Mobile USA in particular, T-Mobile USA does not provide sufficient detail for OpenMarket to distinguish between the two potential causes for the 1020 response code.

• A 1020 response for this carrier may either indicate a system error within T-Mobile USA or the following for the phone number.
• Content Blocking/Blacklisting/Family Allowance is enabled. It is important to note the only way that Content Blocking, Blacklisting, or Family Allowance occurs is if the mobile subscriber called into T-Mobile customer care and specifically requested blocking of short code services.
