Key Takeaways
- Scenario 496 is 17:10 after-school club pickup OTP failover — not exam dawn, homework, enrollment, snow-day, PTC, results, late-bus 15:40, or field-trip 06:50.
- A spare that IT racks at lunch and unplugs at 16:30 is not club-night HA.
- Priced by devices and SMS send volume. You use your own phone and operator SMS credit. Free is 300 SMS lifetime, 1 device. Developer is 25,000 SMS per year.
- Starter is 2 devices; the spare still counts.
- Hold PTA lists until the last pickup code drains.
- Canary both radios at 16:40, not at the noon health check.
Summary
Scenario 496 is after-school club failover. Pickup codes leave Android SIMs you host when clubs dismiss at 17:10. Service pricing is based on device count and total SMS sent through the gateway. You need a working Android phone with a SIM and SMS credit from your mobile operator. Operator message costs are yours—we do not sell carrier SMS balance.
If both phones live in a closet that locked at 16:30, club night is not HA. It is parents at a door with no code.
Not a CodeCanyon “school SMS” pack. Device meters apply — Twilio vs Android SMS gateway.

Context
Authorised adults confirm at the gate. A cancelled club must kill pickup OTP. PTA wants the same hour.
Free (300 SMS lifetime) is a rehearsal house. Developer is 25,000 SMS per year.
Core scenario guidance
Keep primary + spare paired through club hours. Health is last submit after 16:40, not a noon screenshot.
Hold PTA until OTP drain. Locale per family if you span regions.
Club-pickup roles
| Role | When | Typical fail |
|---|---|---|
| Pickup / authorised-adult OTP | 16:50–18:00 parent local | Phone in a locked office after 16:30 |
| Hot spare | Primary unpaired or submit errors | Unplugged when office closed |
| Club cancelled | Kills pickup OTP | Parents arrive for an empty hall |
| PTA / merch | Held until last pickup | Released at 17:00 into OTP |
Cost and ownership
Priced by devices and SMS send volume. You use your own phone and operator SMS credit. The spare is a billed device. Resends burn airtime.
Name a 16:15–18:30 on-call for club nights, not only exam week.
Operations
16:40 canary both radios. Abort: hold PTA, keep pickup OTP. Do not “resend all clubs.”
Security and compliance
Minors: short bodies. No full pupil lists in SMS. Authenticate club-app cancel hooks. PTA is promotional.
Decision guide
Ship when 16:40 canary is green and the spare is reachable after office lock. Delay if phones live in a closet that closes at 16:30. If handsets are forbidden, CPaaS for pickup OTP.

Next steps

Deep dive: production hardening
Cleaners pulling USB at 16:30 is an outage. Watch DLR, not SIS 200s.
Deep dive: scaling and failure modes
Multi-campus club nights add devices before inventing a hidden unlimited-handset SKU. Raise OEM ceilings; fair-use remains.
Deep dive: integration discipline
Idempotency on pupil_id + club_id + local_date. MCP is a REST wrapper — live fields in Developer Center.
Priced by devices and SMS send volume. You use your own phone and operator SMS credit.
16:40 club canary
Unplug primary. Confirm spare takes a staff OTP. Hold PTA during the spike.
