It's simple -- they don't. Instead, the device accesses a server periodically.
It's possible to jump-start the process with an SMS message, rather than blindly polling. This also saves considerable battery power. See, for example: https://labs.ericsson.com/apis/mobile-java-push/downloads The drawback is that the SMS message may not be free. The bottom line is, SMS can contact your phone, but not IP network traffic via the cellular network. Only your phone can initiate the network traffic.
