Key Takeaways
- Scenario 1323 is dual-SIM routing for inland barge / river-lock cutoff SMS — not cross-dock doors, empty off-hire, air ULD, port LFD, rail ramps, bonded HOLD, locker PIN, RTS, or cold-chain.
- “Tow T-18, lock 4, cutoff 16:40” is transactional. “Book more barges” is marketing. Split SIMs.
- Keep the same From on lock notices. A new MSISDN looks like a river scam.
- 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.
- TOS / lock OTP stays off the tow radio.
- REST fields live in Developer Center — not a CodeCanyon barge plugin. MCP, if you use it, is only a REST wrapper.
Summary
Scenario 1323 is logistics dual-SIM for inland barge and river-lock cutoffs. The lock schedule owns the clock. The Android is a radio, not the tow plan. Priced by devices and SMS send volume. You use your own phone and operator SMS credit.
If cutoff leaves SIM A and the “demurrage” reminder leaves SIM B, the shipper will treat the second From as a river scam.
