Key Takeaways
- Scenario 1330 is a school-feeding tally on *116#: the cook posts meals served, not bags issued. Timeout ≠ served. Not chlorine residual, bednets, or VSL.
- A session that dies on the last menu leaves a school marked fed when the pot is still cold.
- Do not SMS pupil names or GPS dumps. School code + meal count + ticket.
- Campaign SMS stays on another device so the USSD modem is not starved.
- Priced by devices and SMS send volume. You use your own phone and operator SMS credit. Free: 1 device / 300 SMS lifetime / 300 contacts. Developer: 25,000 SMS per year.
Android SMS gateway scenario 1330 is a feeding desk. Cooks post meals on *116#. The last screen is served count, not bags issued. Chlorine *117# is the wrong list.

Meals served, not chlorine
One session, one school ticket. Map the last menu to served meals, not a residual log.
If the tree died on “confirm served,” the pot was still cold and the dashboard marked the school fed.
