Key Takeaways
- Scenario 1776 is 16:40 trampoline-park session OTP — not salon, deposit, waitlist, studio, telehealth, vet, garage, driving, notary, implant, visa, physio, optician, tattoo, barber, pilates, nail, massage, yoga, climbing, groomer, kiln, escape-room, language-school, laser-tag, bowling 20:00, padel 19:20, axe-throw 17:30, or ice-rink 18:10.
- A session PIN that sits behind a merch CSV is a no-show that still occupies a court.
- 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 desk spare still counts.
- Hold sock CSV until session OTP drains.
- Canary the desk SIM at 16:20, not at the overnight till job.
Summary
Scenario 1776 is a trampoline pack: session PIN at 16:40, waiver codes after, sock merch held until OTPs drain. 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 the court is live and the PIN is still behind “grip socks 2-for-1,” you did not unlock. You advertised.
Not a CodeCanyon “booking SMS” pack. Device meters apply — Twilio vs Android SMS gateway.

Context
After-school wave starts at 16:40. Jumpers need a PIN at the gate, not a queued one. Marketing still wants a sock CSV.
Free (300 SMS lifetime) is a rehearsal court. Developer is 25,000 SMS per year.
Core scenario guidance
16:40 is trampoline OTP, not laser-tag 16:00. Timezone is the park, not the franchise HQ.
Trampoline OTP roles
| Role | When | Typical fail |
|---|---|---|
| P0 session OTP 16:40 | 16:40 jumper local | Queued behind a sock merch CSV |
| Waiver PIN | Same clock, own template | Merged into the 16:40 body |
| Staff OTP | Transactional, own pool | Dumped onto the park radio |
| Sock / merch | Held until last P0 DLR | Released at 16:10 into desk SMS |
Cost and ownership
Priced by devices and SMS send volume. You use your own phone and operator SMS credit. The desk spare is a billed device. Duplicate PINs burn airtime.
Name a 16:00–18:00 on-call for after-school, not only weekend tills.
Operations
16:20 canary. Abort: hold sock CSV, keep staff OTP, skip a second “all jumpers” blast. Do not “resend courts.”
Security and compliance
Short PINs. No court numbers plus child names in one SMS. Authenticate booking hooks. Sock lists are promotional.
Decision guide
Ship when 16:20 canary is green and P0 stays ahead of merch. Delay if the desk phone sleeps after 15:00. If handsets are forbidden, CPaaS for staff OTP.
Checklist
- Desk SIM paired before 16:00.
- 16:20 canary.
- P0 before merch.
- Staff OTP isolated.
- Sock CSV held.
- Airtime before 16:00.
- Battery exemptions.
- Park locale.
- After-school on-call named.
- Device cap includes spare.
Next steps
Review device and SMS volume pricing, device setup, SMS API documentation.
Deep dive: production hardening
A till reboot at 16:25 is an outage at 16:40. Watch P0 DLR, not booking 200s.
Deep dive: scaling and failure modes
Multi-park after-school waves add devices before inventing a hidden unlimited-handset SKU. Raise OEM ceilings; fair-use remains.
Deep dive: integration discipline
Idempotency on booking_id + kind (session|waiver). 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.
16:20 park drill
Canary. Fire one P0 PIN. Confirm DLR before sock CSV. Hold merch during the wave.
