Common questions
Understanding SMS testing
An SMS testing tool verifies what actually reaches the handset by providing real test numbers across different countries and networks. You send SMS through your existing infrastructure to these test numbers, and the tool reports back exactly what was received, including delivery status, Sender ID, message content, and routing information.
Unlike relying on your SMS vendors' delivery reports, an SMS testing tool gives you independent, ground-truth verification.
A fake DLR (Delivery Report) is a delivery confirmation that claims your message was delivered, when in reality it was not. This can happen at any point in the routing chain, from supplier SMSCs to intermediaries, and isn't always deliberate.
Fake DLRs cost you money while your end users never receive your messages. TelQ detects fake DLRs by comparing reported delivery status against real confirmation from local test handsets.
SMS route quality can change without notice: suppliers switch infrastructure, grey routes get blocked, and Sender IDs get modified by intermediaries.
Without an SMS testing tool, you're flying blind: paying for routes that don't deliver, or damaging your brand because customers receive messages from unknown numbers. Regular testing lets you catch problems before they affect your traffic at scale.
SMSC verification is the process of retrieving the SMSC number and owner from a delivered SMS. This tells you which infrastructure actually carried your message. It lets you verify whether your supplier is using the route they claimed and compare the SMSC country with the test number country.
TelQ provides SMSC number and owner lookup automatically and free of charge for every positively delivered test.
