Key Takeaways
- Scenario 1083 is reefer / cold-chain dwell dual-SIM — not milk-run consolidation, last-mile, yard hold, hazmat, or returns.
- “Trailer T-41 at dock 6, dwell 42 min, temp 2.1°C” is transactional. “Book our extra reefer week” is marketing. Split SIMs.
- Dashboard OTP stays on a dedicated Android. A Saturday produce dump 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 trailer + clock hour. Radio retries still spend operator credit.
- REST send fields live in Developer Center — not a CodeCanyon reefer plugin. MCP, if you use it, is only a REST wrapper.
Summary
Scenario 1083 is logistics dual-SIM for reefer dwell. The WMS owns the trailer clock. SIM A texts the dock. 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 “we called the dock” proof is a promo SIM that also sold extra reefer weeks, you have mixed a temperature hold with a sales blast.
