Testing SMS delivery is essential for every SMS aggregator. Regular monitoring and evaluating of the quality and performance of the routes help you to ensure great customer service. 

SMS testing tools like Testelium usually check the routes you are using and report if the delivery was really made, analyzing the characteristics and types of aforementioned routes. So, what data can you actually get from SMS delivery testing and how can you put it to use? Let’s contemplate these questions in this article.

What is an SMS delivery report?

An SMS delivery report, also known as the DLR, stays for the message that confirms or refutes the fact of SMS delivery. Delivery reports can be sent by default for any message proceeded in the network, so technically, you can get it without any additional testing software.

So in this case, why would you need any service to run test your deliverability, if it is so simple? The truth is that the current market is compromised by scammers and unreliable service providers who generate thousands of fake SMS delivery reports. So, the report from the mobile network operator may not reflect the actual state of your bulk SMS campaigns.

How do SMS delivery reports work?

SMS delivery report is sent by a short message service center (SMSC) when your initial message is submitted to the carrier. The aforementioned report, unfortunately, also doesn’t grant you any guarantee that the recipient actually received the report. It rather shows that the SMS was successfully sent from the device. 

At the same time, unsuccessful SMS delivery may mean the following points:

— the recipient number is out of mobile network reach;

— the mobile device is inactive;

— the recipient number is no longer available;

— the number is invalid or written down in the wrong format;

— the network hasn’t passed the message content;

— and so on.

So, there are a lot of factors in A2P messaging that affect bulk SMS delivery and can sabotage your efforts to build a reliable SMS aggregator. To mitigate these risks, we suggest using SMS delivery testing for two main reasons:

— to run a real check of the delivery and if detect fake DLRs occur on this exact route;

— get the detailed characteristics of the chosen route and determine whether there are any problems that can create difficulties.
