Key Takeaways
- Scenario 1503 is dual-SIM routing for air-cargo ULD / AWB cutoff SMS — not port LFD, rail ramps, bonded HOLD, locker PIN, RTS, or cold-chain.
- “AWB 176-… ULD cutoff 21:10 ZRH” is transactional. “Book our next flight” is marketing. Split SIMs.
- Keep the same From on cutoff notices. A new MSISDN looks like a scam to a shipper.
- 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.
- GHA / portal OTP stays off the ramp radio.
- REST fields live in Developer Center — not a CodeCanyon cargo plugin. MCP, if you use it, is only a REST wrapper.
Summary
Scenario 1503 is logistics dual-SIM for air-cargo ULD and AWB cutoffs. The GHA system owns the clock. The Android is a radio, not the load plan. Priced by devices and SMS send volume. You use your own phone and operator SMS credit.
If cutoff leaves SIM A and the “rebook fee” reminder leaves SIM B, the shipper will treat the second From as a cargo scam.
