Key Takeaways
- A billboard MMS is face ID and panel crop — not a drone still of the whole skyline.
- Ops NOC and the advertiser are different lists. Do not reuse a streetlight photocell template.
- Free is 1 device, 300 SMS lifetime, and 300 contacts. Developer is 25,000 SMS per year. Platform price is devices plus send volume.
- Crew-app OTP stays off the lift radio.
- Idempotency is face-id plus ticket — a wrinkle recut recuts the same work order.
Summary
Scenario 1881 is field-service MMS for billboard face inspections — not streetlight photocells, not cell-tower climbs, not catch-basins, not hydrant flow. Lift-arrive is a hint. Panel crop after vinyl tension is the join. Service pricing is devices plus SMS send volume. You bring the phones and operator credit. Free is 1 device, 300 SMS lifetime, and 300 contacts.
Starter allows 2 devices: lift dual-SIM plus a spare. Uncapped platform volume is not unlimited carrier SMS. Confirm payloads in Developer Center.

face + ticket — wrinkle recut once
A face crop is not a skyline dump
Shop copy names the face and panel. Advertiser alerts live elsewhere. Mixing them is how a technician STOPs the week the only vinyl they own is actually taut.
If dispatch fires “complete” when the lift arrives, the shop thinks the panel is photographed. Join panel crop. Suppress arrive-to-buyer templates.
Billboard MMS matrix
| Event | SMS / MMS | Failure |
|---|---|---|
| Lift arrive | None or “on site” | “Complete” before panel crop |
| Panel crop | Face ID + tension | Book-this stuffed in |
| Wrinkle recut | Once after new crop | Two complete texts |
| Crew OTP | Auth pool | OTP on the lift radio |
Panel crop vs lift arrive
Persist face-id plus ticket. DLR. MCP wraps REST only.
Creative is not auto-reply
The MMS is that face. An inventory newsletter is marketing. FTC business guidance is not a reason to hide the crop behind a book-this-board blast.
Devices, volume, and airtime
Campaign changeovers spike. We meter devices and platform sends. Free (1/300/300) is one face proof.
Lift operations
Charge the lift chassis before first rise. Setup, Downloads, pricing.
Decision guide
Ship when notice joins panel crop. Delay if arrive texts “complete.” Not a CodeCanyon OOH pack.
Face checklist
- Face plus ticket idempotency.
- Arrive silent as complete.
- Inventory off shop purpose.
- OTP off lift SIM.
- Developer Center fields confirmed.
