Key Takeaways
- Scenario 423 is grain-elevator dump dual-SIM — not livestock rest, oversize escorts, RO-RO ferry ramps, returns inbound, air-cargo ULD, rail-ramp, hazmat placards, cross-dock transload, bonded customs, empty-container pickup, reefer dwell, milk-run consolidation, last-mile, or yard hold.
- “Pit GY-4 open — dump 14:20, lane 2” is transactional. “Book our extra harvest week” is marketing. Split SIMs.
- Dashboard OTP stays on a dedicated Android. A harvest pile will starve it.
- Priced by devices and SMS send volume. You use your own phone and operator SMS credit. Free is 1 / 300 / 300. Developer is 25,000 SMS per year.
- Idempotent on pit + clock hour. Radio retries still spend operator credit.
- REST send fields live in Developer Center — not a CodeCanyon grain plugin. MCP, if you use it, is only a REST wrapper.
Summary
Scenario 423 is logistics dual-SIM for grain-elevator dumps. Scale owns the pit. SIM A texts the driver a lane and a clock. Priced by devices and SMS send volume. You use your own phone and operator SMS credit.
If the pit number changes mid-harvest, the driver treats the next lane ping as spam — and you lose the only clock that matches the scale ticket.
