Key Takeaways
- Scenario 1656 is 17:30 axe-throw lane 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, or padel 19:20.
- A lane PIN that sits behind a merch CSV is a no-show that still occupies a throwing bay.
- 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 kit CSV until lane OTP drains.
- Canary the desk SIM at 17:10, not at the overnight till job.
Summary
Scenario 1656 is an axe-throw pack: lane PIN at 17:30, waiver codes after, kit 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 bay is live and the PIN is still behind “new hatchets 10% off,” you did not unlock. You advertised.
Not a CodeCanyon “booking SMS” pack. Device meters apply — Twilio vs Android SMS gateway.

Context
First throw is 17:30. Guests need a PIN at the cage, not a queued one. Marketing still wants a kit CSV.
Free (300 SMS lifetime) is a rehearsal bay. Developer is 25,000 SMS per year.
Core scenario guidance
17:30 is axe-throw OTP, not climbing 17:50. Timezone is the venue, not the franchise HQ.
Axe-throw OTP roles
| Role | When | Typical fail |
|---|---|---|
| P0 lane OTP 17:30 | 17:30 thrower local | Queued behind a kit merch CSV |
| Waiver PIN | Same clock, own template | Merged into the 17:30 body |
| Staff OTP | Transactional, own pool | Dumped onto the lane radio |
| Kit / merch | Held until last P0 DLR | Released at 17:00 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 16:50–19:00 on-call for weeknights, not only weekend tills.
Operations
17:10 canary. Abort: hold kit CSV, keep staff OTP, skip a second “all throwers” blast. Do not “resend lanes.”
Security and compliance
Short PINs. No bay numbers plus names in one SMS. Authenticate booking hooks. Kit lists are promotional.
Decision guide
Ship when 17:10 canary is green and P0 stays ahead of merch. Delay if the desk phone sleeps after 16:00. If handsets are forbidden, CPaaS for staff OTP.
Checklist
- Desk SIM paired before 16:50.
- 17:10 canary.
- P0 before merch.
- Staff OTP isolated.
- Kit CSV held.
- Airtime before 16:50.
- Battery exemptions.
- Venue locale.
- Weeknight 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 17:15 is an outage at 17:30. Watch P0 DLR, not booking 200s.
Deep dive: scaling and failure modes
Multi-site weeknights add devices before inventing a hidden unlimited-handset SKU. Raise OEM ceilings; fair-use remains.
Deep dive: integration discipline
Idempotency on booking_id + kind (lane|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.
17:10 lane drill
Canary. Fire one P0 PIN. Confirm DLR before kit CSV. Hold merch during the wave.
