Methods and systems for verifying installation of a networked device are disclosed. Short message service (SMS) messages are used to communicate between an in-field device and a central computer system after an installation of a network device. The in-field device request an installation verification process be executed by the central computer system. The central computer system first requests an installation number from the in-field device, and then contacts a gateway networked to the network device to perform an installation verification test. The results of the test are sent to the in-field device via SMS.
