Key Takeaways
- Scenario 603 is ferry / RO-RO ramp dual-SIM — not 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.
- “Ramp RR-7 ready — lane 4, sailing 14:20” is transactional. “Book our extra sailing week” is marketing. Split SIMs.
- Dashboard OTP stays on a dedicated Android. A holiday sailing 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 sailing + clock hour. Radio retries still spend operator credit.
- REST send fields live in Developer Center — not a CodeCanyon ferry plugin. MCP, if you use it, is only a REST wrapper.
Summary
Scenario 603 is logistics dual-SIM for RO-RO ferry ramp. The TOS owns the sailing. SIM A texts the trucker. SIM B never rides that inbox. Priced by devices and SMS send volume. You use your own phone and operator SMS credit.
If the only “ramp is ready” proof is a promo SIM that also sold extra sailing weeks, you have mixed a ferry clock with a sales blast.
