SMSC verification

We can retrieve SMSC information once your test message reaches our testing device. This information can help you to determine the route type and, potentially, the original provider of the route.

SMSC number

We provide the exact SMSC number from which the SMS was sent.

SMSC owner

We make an SMSC lookup and try to determine the owner of the SMSC.
