Key Takeaways
- Scenario 543 is oversize / pilot-car escort dual-SIM — not 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.
- “Escort OS-12 ready — window 04:00, mile 18” is transactional. “Book our extra permit week” is marketing. Split SIMs.
- Dashboard OTP stays on a dedicated Android. A holiday permit 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 permit + clock hour. Radio retries still spend operator credit.
- REST send fields live in Developer Center — not a CodeCanyon oversize plugin. MCP, if you use it, is only a REST wrapper.
Summary
Scenario 543 is logistics dual-SIM for oversize / pilot-car windows. Dispatch owns the permit. SIM A texts the driver a window and a mile marker. Priced by devices and SMS send volume. You use your own phone and operator SMS credit.
If the escort number changes mid-run, the driver treats the next mile ping as spam — and you lose the only clock that matches the permit.
