Android SMS Gateway Scenario 1306: NGOs USSD requests in practice

Summary

Scenario 1306 is an IDP ration dawn: *190# records the issue, SMS confirms the household, 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 the warehouse count matches and families never got the SMS, you inventoried sacks. You did not issue breakfast.

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

Key takeaways

• Scenario 1306 is *190# IDP food ration then household SMS — not distribution-eve, surveys, *182#, KYC, disaster, cash-for-work, school-feeding, complaint, livestock, poll, borehole, birth, nutrition, vax, cash *550#, camp *150#, ANC, school-roll, *360# nets, *400# teachers, or *260# water votes.
• A USSD 200 without the follow-up SMS is a ration logged in HQ the family 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 ration confirmation SMS drains.
• Canary *190# plus SMS at 06:40, not at HQ 09:00.

Context

Queues open at 06:50. Households walk at first light. Fundraising still wants an appeal CSV.

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

Core scenario guidance

*190# is ration issue, not camp *150# registration. Timezone is the camp, not the capital office.

Ration 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 06:20–11:00 on-call for ration dawns, not only HQ weekdays.

Operations

06:40 canary *190# and SMS. Abort: hold donate, keep staff OTP, skip a second “all households” blast. Do not “resend camp.”

Security and compliance

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

Decision guide

Ship when 06:40 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 06:20.
• 06:40 canary *190# + SMS.
• Spare live before 06:50.
• Staff OTP isolated.
• Donate held.
• Airtime before 06:20.
• Battery exemptions.
• Camp locale.
• Ration-dawn 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 07:00 is an outage mid-queue. Watch USSD session + SMS DLR, not MIS 200s.

Deep dive: scaling and failure modes

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

Deep dive: integration discipline

Idempotency on household_id + ration_date + 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.
