Key Takeaways

  • Scenario 1930 is a community-health-worker weekly commodity stock USSD (*884#). Timeout is not zero stock — not teacher staff-roll, WASH kits, or cold-chain.
  • A timeout that posts as “0 ORS” empties a restock truck that never needed to roll.
  • Do not SMS patient names or lot numbers. Menu codes and facility 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.
