Key Takeaways
- Scenario 273 is crawlspace vapor-barrier commissioning MMS — not attic baffles, garage-door springs, french drains, gutter guards, water-heater anodes, sump pits, window-film panes, channel letters, EV chargers, auto-gates, pool pads, FACP zones, solar strings, standby generators, utility-trim cuts, septic lids, HVAC stickers, irrigation valves, roof IR squares, elevator plaques, extinguisher tags, scaffold cards, meter dials, hazmat bags, LOTO, night keys, storm claims, or closeout selfies.
- A cropped seam and staple line are the payload. Do not MMS interiors, plates, or neighbor yards.
- Read MMS and “we commissioned” SMS must not share a radio with portal OTP or an “add dehumidifier” blast.
- Priced by devices and SMS send volume. You use your own phone and operator SMS credit. Free is 1 / 300 / 300. Developer is 25,000 SMS per year.
- Operator MMS is usually dearer than SMS. Budget wet-week installs separately.
- REST attachment fields live in Developer Center — not a CodeCanyon crawlspace add-on. MCP, if you use it, is only a REST wrapper.
Summary
Scenario 273 is field MMS for crawlspace vapor-barrier commissioning. The work order owns the bay id. The Android sends a cropped face so the desk can close the file. Priced by devices and SMS send volume. You use your own phone and operator SMS credit.
If the only proof the seam taped is an MMS the APN dropped, you do not have a file. You have another verbal “it looks white.”
