Key Takeaways
- Ice-machine MMS is unit last-four and harvest-cycle condensate — not a kitchen panorama on the radio.
- Hash the site id into the caption. A generic “ice ok” photo is not an acceptance packet.
- Keep dispatch OTP off the tablet that dumps harvest bursts.
- Service pricing is devices plus SMS send volume. You bring the Android phone and operator credit.
- Free is 1 device, 300 SMS lifetime, 300 contacts. Developer is 25,000 SMS per year.
- Honor STOP on warranty nags. Harvest photos stay transactional; upsell cubes do not.
Summary
Field MMS in scenario 1569 is commercial ice: harvest-cycle condensate and cube-bridge crop, unit last-four in the caption. Unlike job photos, warranty RMA, inspection, before/after, sign-off pad, nameplate, meter-read, leftover-parts, VIN, scale-tape, attic hatch, solar string, fire-alarm zone, EV charger, elevator recall, boiler combustion, generator ATS, pool ORP, water-heater anode, septic baffle, rooftop HVAC coil, irrigation valve, chimney flue, garage torsion, locksmith cylinder, or IGU spacer, this packet is ice harvest, not glass spacer.
Service pricing is devices plus SMS send volume. You bring the Android phone and operator SMS credit. Free is 1 device, 300 SMS lifetime, 300 contacts. Developer is 25,000 SMS per year. Starter, Professional, and Business list Unlimited SMS as platform send volume; devices and airtime stay metered.
A kitchen panorama is not an ice packet. Crop the harvest. Send unit last-four. Keep the ice-bin serial in the work order.

Context
Refrigeration desks land here after a 12 MB bin photo failed OEM size caps, or after a full serial leaked in a caption. Dispatch OTP cannot share that tablet.
Core scenario guidance
Crop harvest. Template: unit last-four. Drop full serials. Honor STOP on nags. Isolate OTP.
| Lane | MMS body | Fail closed |
|---|---|---|
| Harvest crop | Condensate + last-four | Kitchen panorama |
| Retry | Same work-order id | Second packet |
| STOP | Suppress cube upsell | Keep harvest MMS |
| Dispatch OTP | Separate device | Same SIM as harvest burst |
Canary a staff unit after OS updates. MCP wraps REST. Developer Center owns fields.
Cost and ownership
Devices + volume + operator airtime on every retry. Developer is 25,000 SMS per year. Free (1 / 300 / 300) proves pairing, not a refrigeration desk.
Operations
Daily last-seen, battery, duplicate work-order ids. After an OEM MMS cap change, one staff canary. On-call before unattended banquet ice pulls.
Security and compliance
Ice-bin serials identify assets. Encrypt at rest. Never log full serials from captions. Verify TLS on every callback.
Decision guide
Ship when crop rules, last-four templates, STOP, and OTP isolation exist. Delay if a panorama can still fire. If zero phone ops is mandatory, evaluate CPaaS for that slice.
Checklist
- Harvest crop only.
- No full serial in MMS.
- Honor STOP on nags.
- OTP isolated.
- Spare paired.

Deep dive: production hardening
Size caps before radio are non-negotiable. A panorama still spends airtime when it fails. Battery exemptions dominate overnight ice pulls.
Deep dive: scaling and failure modes
Scale is work orders times harvest photos, not a blast of the kitchen. Never claim unlimited free cloud SMS credits with no device or volume meter.
Deep dive: integration discipline
Developer Center owns live API parameters. Persist work-order id. MCP is a REST wrapper. If zero phone ops is mandatory, evaluate CPaaS. You bring the Android phone and operator credit.
