Key Takeaways
- A food-truck “we’re at 5th and Pine until 21:00” text is operational for subscribers who asked. A city-wide blast is promo with STOP.
- HELP must name tonight’s pin, not last Saturday’s lot.
- Free is 1 device, 300 SMS lifetime, and 300 contacts. Platform price is devices plus send volume; you buy the phone and airtime.
- Auto-reply never promises a parking stall or a weather guarantee.
- Gift-card OTP stays off the truck radio.
Summary
Scenario 271 is restaurant auto-reply and STOP for food trucks and pop-ups — not a dining room, not a ghost kitchen pass, not catering. The kitchen moves. Subscribers expect today’s pin, not a stale lot from the CRM. Service pricing is devices plus SMS send volume. You bring the phone and operator credit. Free is 1 device, 300 SMS lifetime, and 300 contacts.
Starter allows 2 devices: pin-ops vs promo. Uncapped platform volume is not unlimited carrier SMS. Confirm keywords in Developer Center.

HELP never quotes last week’s lot
The truck moves; the number should not lie
Pin SMS: address, hours, sold-out flag. Promo: merch, catering upsell, STOP. Do not reuse yesterday’s template without a human confirm that the truck is actually there.
STOP handling, transactional alerts.
If rain cancels the lot and auto-reply still says “see you at 17:00,” you will host a puddle of angry walk-ups. Weather cancel is a human send, then a suppress on further pin texts that night.
Pop-up STOP matrix
| Inbound | Action | Failure |
|---|---|---|
| STOP | Mute pin + promo unless they said ops-only | Still blasting last week’s lot |
| WHERE | Tonight’s confirmed pin | CRM last-location |
| Weather / cancel | Human, then suppress | Bot “we’re open” |
| Catering ask | Human inbox | Auto-book a date the truck cannot staff |
Tonight’s pin vs last week’s lot
Source of truth is the shift sheet, not a stale GPS ping. Quiet hours after the window closes. Google Ads SMS/MMS policy for merch blasts.
Weather cancel is human
Auto-reply acknowledges. The owner cancels. Webhooks. MCP, if used, wraps REST — it does not invent a pin.
Devices, volume, and airtime
We meter devices and platform sends. Free (1/300/300) is a weekend rehearsal.
Service-window operations
Charge in the cab, pairing, pin confirmed before the first SMS. Setup, Downloads, pricing.
Decision guide
Ship when WHERE cannot return a stale lot. Delay if the truck’s personal phone is the list. Not a CodeCanyon “unlimited SMS” pack.
Pop-up checklist
- Pin confirmed before send.
- STOP scoped.
- Weather cancel is human.
- OTP isolated.
- Developer Center keywords confirmed.
