Key Takeaways
- Scenario 1713 is after-hours key-safe / alarm-panel MMS — not LOTO, storm claims, warranty plates, or customer sign-off.
- A key-tag number is enough. Do not MMS the full alarm keypad or a street-facing wide shot at 02:00.
- Night MMS and “guard ETA” SMS must not share a radio with portal OTP or a monitoring-upsell 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 false-alarm nights separately.
- REST attachment fields live in Developer Center — not a CodeCanyon alarm add-on.
Summary
Scenario 1713 is field MMS for after-hours key and alarm jobs. The ticket owns the site id. The Android sends a cropped key-tag or “box opened” stub when the runner has no trusted data path. Priced by devices and SMS send volume. You use your own phone and operator SMS credit.
If the only copy of the key-safe combo is an MMS sitting on a personal phone, you published the site.
