Unlock the complexity of SMS messaging through a comprehensive set of testing tools available anytime, anywhere

SMS messaging is a complex environment. Due to a fragmented supply chain and scarce end-to-end information system by design, SMS are not provided with transparent QoS.

TestSMS helps you verifying the quality of your messaging connections by combining a plug and play management interface and an extensive network of end-user devices globally located.

Verify SMS Delivery

Get real-time SMS reciept info from live devices and detect Fake DLR.

Control SMS features

Verify SenderID support, MNP accuracy, content changes, and all SMS properties.

Assure Time

Gather information on the end-to-end delivery speed and check your message is delivered in a timely manner.

Service concept

Leveraging on a large network of nodes, populated via a consumer Mobile App, TestSMS guarantees that the testing numbers managed through the platform are always online and continuously rotated. In combination with the absence of unique ID in the message content and dynamic content generation, this guarantees that tests are performed on users phones never grasped by SMS routing algorithms, often subject to "white-listing", aiming to simulate a real end-to-end SMS delivery experience.

“Thanks to TestSMS we managed to improve by 20% the conversion of our Marketing Campaigns identifying SMS gateway with a high percentage of Fake DLR”

― Matt Johnson
