Key Takeaways
- Scenario 1750 is a seed-pack redemption USSD (*553#). Timeout is not a redeemed voucher — not IDP headcount, MUAC, or CHW stock.
- A timeout that posts as “redeemed” empties a warehouse bag that never left the shelf.
- Do not SMS farmer names or lot numbers. Menu codes and coop PIN only.
- Supervisor portal OTP stays on another device.
- 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 1750 is a planting-season desk. Coop clerks dial *553# and step crop, kilo, PIN. A timeout is not a redemption. Nightly camp counts and MUAC trees are the wrong list.

Seed pack, not headcount
Planting window. Map session id to coop. 08:00 is a timeout queue, not a warehouse out.
If 50 sessions timed out and you posted redeemed, the store emptied bags nobody collected.
