Key Takeaways
- Scenario 1030 is a vaccine cold-chain check on *111#: the nurse posts °C after opening the fridge, not “checked.” Timeout ≠ in-range. Not GESI referrals, cash vouchers, or boreholes.
- A session that dies on the last menu leaves a fridge marked safe when the logger is still in the red.
- Do not SMS site names or GPS dumps. Site code + temp + 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 1030 is an immunization desk. Nurses post fridge temp on *111#. The last screen is °C in range, not “opened.” GESI *112# is the wrong list.

Fridge in-range, not GESI
One session, one site ticket. Map the last menu to °C, not a referral flag.
If the tree died on “confirm temp,” the logger was still red and the dashboard marked the fridge safe.
