Example 2 of 4: Toll-free Message delivered to handset

  • Toll free phone numbers support "device-level" delivery receipts which indicate that the end-users device has received the message.
  • A timeout response with error-code : 9902 - Timed out waiting for delivery receipt. The reason a delivery receipt was not received is not known. does not indicate that the message was not received. Only that the end-users' device did not communicate back to the network indicating the message was received during the DLR timeout window.
  • A DLR when the from number is toll-free and the status is ok indicates that the message was indeed delivered to the end users' device.
