It's worth looking at the $40 Adafruit FONA cellular modem with inexpensive Ting month-to-month cellular service. We've been using it and it's great! I'm happy to share my simple Raspberry Pi serial port glue code that connects to Intermapper's paging interface via a local web service. Add a GPS board and you can make it double as a GPS-based time server, since FONA will extract time and latlong from GPS and make it accessible via the serial port. -mel beckman -mel beckman

Verizon does have an enterprise messaging service with API hooks, such as using SNPP instead of email-to-sms.
