Key Takeaways

What is an SMS Delivery Report?

There are multiple reasons and quite a lot of times when text messages do not get delivered. This is the situation where an SMS delivery report comes to the rescue.

An SMS Delivery Report, also known as a delivery receipt (DLR), is a notification sent back to the sender (usually a business or service provider) confirming the delivery status of an SMS message.

It informs the sender whether the message has been successfully delivered to the recipient’s mobile device or if it encountered any issues during transmission. The SMS delivery report is available for both P2P and A2P messaging.

How SMS Delivery Reports Work in A2P Messaging?

When an SMS message is sent, it travels through a series of steps before reaching the recipient. Here’s a simplified process of how an SMS delivery report is generated:

  1. Message Submission: The sender composes an SMS and submits it to the SMS gateway or SMS service provider.
  1. Routing: The SMS gateway processes the message and forwards it to the recipient’s mobile network.
  1. Delivery Attempt: The recipient’s mobile network attempts to deliver the message to the recipient’s mobile device.
  1. Delivery Report Generation: Once the delivery attempt is made, the mobile network generates a delivery report indicating the success or failure of the delivery attempt.
  1. Notification: The delivery report is sent back to the SMS gateway, which then relays the information to the sender in an SMS dashboard.

How SMS Delivery Reports Work in P2P Messaging?

The SMS delivery report would vary depending on which operating system do you use – iOS or Android.  

An Android user can go to: -

Settings>> Text messages>> Toggle SMS delivery reports on or off

An iOS user can turn the read receipts on or off according to their preference. To enable the same, iPhone users can go to: -

Settings>> Messages>> Toggle Send read receipts on or off

Types of Delivery Reports

Delivery reports can provide various types of information, including:

  1. Delivered: The message was successfully delivered to the recipient’s mobile device.
  1. Failed: The message could not be delivered due to issues such as an invalid phone number, the recipient’s phone being switched off, or network problems.
  1. Pending: The delivery attempt is still in progress, often due to temporary network issues or the recipient’s device being temporarily unreachable.
  1. Rejected: The message was rejected by the recipient’s mobile network, possibly due to spam filters or other restrictions.
