Key Takeaways
- Scenario 243 is yard-jockey / hostler dual-SIM — not mailbags, motorcycle hops, grain dumps, 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, parcel lockers, or yard hold as a marketing blast.
- “Spot YJ-2 ready — door 9, 03:15” is transactional. “Book our extra jockey week” is marketing. Split SIMs.
- Dashboard OTP stays on a dedicated Android. A night 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 spot + clock hour. Radio retries still spend operator credit.
- REST send fields live in Developer Center — not a CodeCanyon jockey plugin. MCP, if you use it, is only a REST wrapper.
Summary
Scenario 243 is logistics dual-SIM for yard-jockey spots. Dispatch owns the spot. SIM A texts the hostler a door and a clock. Priced by devices and SMS send volume. You use your own phone and operator SMS credit.
If the spot number changes mid-shift, the hostler treats the next door ping as spam — and you lose the only clock that matches the trailer.
