Abstract
Presented herein are techniques for enabling the zero touch deployment of devices having an integrated wireless wide area network (WWAN) interface. In one example, a method includes initializing a device with a WWAN interface such that the device attaches to a WWAN, receiving, via the WWAN interface of the device, a data message that includes encrypted bootstrap configuration information, obtaining a key stored in a subscriber identification module (SIM) card of the WWAN interface, decrypting the encrypted bootstrap configuration information using the key, establishing communication with a remote server using the bootstrap configuration information and obtaining configuration data from the remote server, and performing self-configuration of the device using the configuration data.
