30003 Unavailable or unreachable

Likely Causes

  • The destination handset you are trying to reach is switched off or otherwise unavailable.
  • The device you are trying to reach does not have sufficient signal
  • The device cannot receive SMS (for example, the phone number belongs to a landline)
  • There is an issue with the mobile carrier

Possible Solutions

The first step to troubleshooting this issue is to attempt to replicate the problems. Try sending another test message to this number after two business days. If the error continues, contact support@rallycorp.com for guidance.

30005 Unknown and may no longer exist

Likely Causes

  • The destination number you are trying to reach is unknown and may no longer exist.
  • The device you are trying to reach is not on or does not have sufficient signal.
  • The device cannot receive SMS (for example, the phone number belongs to a landline)
  • There is an issue with the mobile carrier

Possible Solutions

The first step to troubleshooting this issue is to attempt to replicate the problems. Attempt to send another test message to this number, if the error persists and you are certain this is a mobile number, try the following:

  1. Is the destination device powered on?
  2. Does the device have a strong signal?
  3. If not power the device off, wait 30 seconds, and then power it back up.
  4. Is the device connected to the home carrier's network? We cannot guarantee message delivery on devices roaming off-network.
  5. Can the device receive a text message from a service besides Rally Corp?
  6. Can the device receive messages from another Rally platform number (non-Alphanumeric Sender ID), or with a shorter one-segment (non-concatenated) body?
  7. Can other devices using the same mobile carrier receive your messages?

If the problem persists, contact support@rallycorp.com for guidance. 

30006 Landline or unreachable carrier

Possible Causes

The destination number is unable to receive this message. Potential reasons could include trying to reach a landline or, in the case of shortcodes, an unreachable carrier.

Possible Causes

Your message was sent to a landline or an unreachable carrier for this phone number type.

Possible Solutions

Use the Rally Lookup API to determine if the number is indeed a landline. If is not, try with an alternative phone number type.

30008 Failed for unknown reasons

If a message you sent is not delivered to the end device and returns a 30008 error code, this means that delivery of your message failed for unknown reasons.

When Rally Corp receives a very generic error from our carrier partner that we have no further details about, we associate the message with the error code 30008, letting you know that we don’t know what caused this error from the provider.

Possible Solutions

  • Check that the phone you were sending to is turned on and can receive texts from other sources
  • Ensure that the phone is not roaming off network. We cannot guarantee message delivery on roaming phones.
  • Try sending to other phones who have the same mobile carrier (you can use our Lookups API to determine the carrier if you’re unsure). If messages to other phones go through, the issue is likely device related. Try rebooting the device or contact the mobile carrier for help.
  • If you are sending SMS from an alphanumeric sender ID, see if using another Rally Platform number works better. We’ve observed that certain networks may block alpha sender IDs.
  • Try sending a shorter message to the phone, with simple content that does not include any special characters. This would give our support team an idea as to whether the failure is related to concatenation or character encoding.
  • Rally support can help investigate what went wrong with our carriers. Please open a support request and include a minimum of 3 or more message examples where this error occurred.
