Key Takeaways
- Scenario 1450 is a bednet hang-up tally on *119#: the volunteer posts nets hung, not nets issued. Timeout ≠ hung. Not VSL deposits, MUAC, or CHW stock.
- A session that dies on the last menu leaves a village counted as covered when the nets are still in the sack.
- Do not SMS household names or GPS dumps. Code + net 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 1450 is a malaria campaign desk. Volunteers hang nets and post on *119#. The last screen is hung count, not issued count. VSL *118# deposits are the wrong list.

Bednet hang-up, not VSL
One session, one household ticket. Map the last menu to hung nets, not a savings ledger.
If the tree died on “confirm hang,” the sack was still full and the dashboard lied about coverage.
