Android SMS Gateway Scenario 1366: NGOs USSD requests in practice

Summary

Scenario 1366 is seed-pack issue: *320# records the pack, SMS confirms the farmer, donate CSV waits until receipts drain. Service pricing is based on device count and total SMS sent through the gateway. You need a working Android phone with a SIM and SMS credit from your mobile operator. Operator message costs are yours—we do not sell carrier SMS balance.

If HQ counts match and farmers never got the SMS, you inventoried bags. You did not open planting.

Not a CodeCanyon “NGO SMS” pack. Device meters apply — Twilio vs Android SMS gateway.

Key takeaways

• Scenario 1366 is *320# seed-pack issue then farmer SMS — not distribution-eve, surveys, *182#, KYC, disaster, cash-for-work, school-feeding, complaint, livestock *330#, poll, borehole, birth, nutrition, vax, cash, camp, ANC, school-roll, *360# nets, *400# teachers, *260# water, or *190# rations.
• A USSD 200 without the follow-up SMS is a pack logged in HQ the farmer never hears about.
• Priced by devices and SMS send volume. You use your own phone and operator SMS credit. Free is 300 SMS lifetime, 1 device. Developer is 25,000 SMS per year.
• Starter is 2 devices; the field spare still counts.
• Hold donate blasts until seed confirmation SMS drains.
• Canary *320# plus SMS at 08:20, not at HQ 09:00.

Context

Queues open at 08:30. Farmers walk at first light after market. Fundraising still wants an appeal CSV.

Free (300 SMS lifetime) is a rehearsal cluster. Developer is 25,000 SMS per year.

Core scenario guidance

*320# is seed issue, not livestock *330#. Timezone is the field, not the capital office.

Seed USSD roles

Cost and ownership

Priced by devices and SMS send volume. You use your own phone and operator SMS credit. The field spare is a billed device. Duplicate USSD still burns airtime.

Name a 08:00–13:00 on-call for planting mornings, not only HQ weekdays.

Operations

08:20 canary *320# and SMS. Abort: hold donate, keep staff OTP, skip a second “all farmers” blast. Do not “resend district.”

Security and compliance

Short receipts. No farmer roster plus GPS in one SMS. Authenticate MIS hooks. Donate lists are promotional.

Decision guide

Ship when 08:20 canary is green and the radio stays powered through the queue. Delay if phones lock in the store overnight. If handsets are forbidden, CPaaS for staff OTP.

Checklist

• Field SIM paired before 08:00.
• 08:20 canary *320# + SMS.
• Spare live before 08:30.
• Staff OTP isolated.
• Donate held.
• Airtime before 08:00.
• Battery exemptions.
• Field locale.
• Planting-morning on-call named.
• Device cap includes spare.

Next steps

Review device and SMS volume pricing, device setup, SMS API documentation.

Deep dive: production hardening

Generators dying at 09:00 is an outage mid-queue. Watch USSD session + SMS DLR, not MIS 200s.

Deep dive: scaling and failure modes

Multi-district planting weeks add devices before inventing a hidden unlimited-handset SKU. Raise OEM ceilings; fair-use remains.

Deep dive: integration discipline

Idempotency on farmer_id + season_id + kind (ussd|sms). MCP is a REST wrapper — live fields in Developer Center.

Priced by devices and SMS send volume. You use your own phone and operator SMS credit.

Canary *320#. Confirm receipt SMS. Hold donate during the wave.
