Texter is an SMS-route quality testing tool that uses live nodes.

With Texter, we aim to provide you with a testing method, that minimizes testing inaccuracies. For example the “whitelisting” of numbers, as well as fake DLR, grey routing detection, and more.


To make use of our Texter API you need to be registered at and you need to be acquired in the Texter app.

You can request access via the contact center on the Texter product page

How it works

To use Texter, you supply us with an operator you want to test. We respond with a phone number and a 16 character key that must be in the SMS message that you want to send.
After we give you the phone number, it will be your responsiblity to send the SMS message yourself. The Texter API doesn't send the SMS for you

After you send your test message with the supplied text, we provide you with the details of the potential delivery on the handset. Details such as whether the message has arrived, when it arrived and what has been arrived.
You can receive these test details by providing us with a webhook URL to your own API or poll them from the Texter API.

We do our best to provide you with test nodes that have a good and stable internet connection. But it happens sometimes that our live test nodes don't have a perfect stable internet connection.
However, it can happen that we receive the result of our test node several hours after you sent your test message due to slow internet connection. Despite receiving a result several hours later, we will still send it to your callback API.
