Key Takeaways
- Scenario 1150 is a cash-voucher tally on *113#: the cashier posts paid, not “queued.” Timeout ≠ paid. Not borehole yield, livestock jabs, or feeding.
- A session that dies on the last menu leaves a household marked paid when the envelope is still in the box.
- Do not SMS names, amounts, or GPS dumps. Point code + paid flag + 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 1150 is a cash desk. Cashiers post on *113#. The last screen is paid, not queued. Borehole *114# is the wrong list.

Paid posted, not yield
One session, one household ticket. Map the last menu to paid, not a borehole log.
If the tree died on “confirm paid,” the envelope was still in the box and the dashboard marked the household done.
