Key Takeaways
- Annual elevator MMS is a cropped car-top data plate plus governor tag — not a selfie in the lobby that “proves” the tech was there.
- Red-tag photos go to the AHJ / building-owner queue. Occupant SMS is out-of-service / restored only — no deficiency crop.
- Free is 1 device, 300 SMS lifetime, and 300 contacts. Developer is 25,000 SMS per year. Platform price is devices plus send volume.
- Occupant login OTP stays off the inspection SIM.
- Idempotency is unit-id plus inspection-year — techs retake the same plate.
Summary
Scenario 501 is field-service MMS for elevator and lift annual inspections — not fire-alarm panels, not HVAC commissioning, not DVIR, not meters. The photo that matters is the car-top data plate and the governor tag, cropped so a reviewer can read the unit number. 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: inspection dual-SIM plus a spare. Uncapped platform volume is not unlimited carrier SMS. Confirm MMS fields in Developer Center.

A car-top plate is not a lobby selfie
The reviewer needs the manufacturer plate and the last-test punch, not the tech’s face by the hall lantern. Reject shots that fail OCR on the unit ID. Occupant SMS never carries the red-tag crop.
MMS gateway, transactional SMS.
If the tech uploads a wide lobby photo and the desk closes the work order, the AHJ later asks for the car serial and you have nothing. Gate close on a readable plate crop, not on “photo attached.”
Lift MMS matrix
| Shot | Audience | Failure |
|---|---|---|
| Car-top plate | AHJ / owner | Lobby selfie closes the job |
| Governor / red-tag | AHJ / owner | Occupant sees a fail crop |
| Out-of-service SMS | Occupants | Deficiency text to the building |
| Retake same year | Same unit-id | Duplicate “inspected” texts |
Unit number and crop
Persist unit-id plus inspection-year. Signed webhooks. Webhooks, DLR. MCP wraps REST only.
Red-tag vs occupant SMS
Red-tag stays on the compliance thread. Occupants get date-only out-of-service / restored. ASME A17.1 is the inspection language — not a reason to MMS the whole code book.
Devices, volume, and airtime
MMS is heavier than SMS. We still meter devices and platform sends; you pay the operator. Free (1/300/300) is one car proof.
AHJ operations
Charge the inspection chassis before the annual window. Setup, Downloads, pricing.
Decision guide
Ship when close requires a readable plate. Delay if a selfie closes the order. Not a CodeCanyon lift pack.
Lift checklist
- Year-keyed idempotency.
- OCR gate on the plate.
- Red-tag crop off occupant SMS.
