Key Takeaways
- Scenario 1600 is a sports-physical deadline blast at 16:10: the forms SIM dies under the parent spike — a spare already paired takes the rest. Not Chromebook checkout, bus-route, or SIP.
- Families who get silence will clog the nurse line the night before tryouts. The product is the second radio.
- Do not SMS student names or medical findings in message 1. Desk, hours, and a short PIN if you must.
- Staff 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 1600 is an athletics desk. Parents get “physicals due tonight 18:00, nurse window.” The forms SIM cooks at 16:10. A spare already hot takes the rest. Cart checkouts and route dawns are the wrong list.

Physicals, not a cart
Pair the spare at lunch. 16:12 is a failover, not a firmware update.
If 180 parents were queued and one radio died, tryouts filled with kids whose forms never arrived.
