Key Takeaways
- Scenario 1203 is dual-SIM routing for customs / government exam-hold SMS — not cargo-bike bays, river locks, cross-dock doors, empty off-hire, air ULD, port LFD, rail ramps, bonded CFS HOLD, locker PIN, RTS, or cold-chain.
- “Entry E-8821 selected for exam — CET 09:00” is transactional. “Use our broker” is marketing. Split SIMs.
- Keep the same From on exam notices. A new MSISDN looks like a customs 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.
- Broker / portal OTP stays off the exam radio.
- REST fields live in Developer Center — not a CodeCanyon customs plugin. MCP, if you use it, is only a REST wrapper.
