Key Takeaways
- Election-ballot dual-SIM is sealed pouches scanned at the receiving clerk — not vault packed, not a GOTV newsletter.
- Warehouse and route SIMs split: one for vault, one for precinct fallback.
- Free is 1 device, 300 SMS lifetime, and 300 contacts. Developer is 25,000 SMS per year. Platform price is devices plus send volume.
- Staff-app OTP stays off the courier radios.
- Idempotency is run-id plus seal-scan — a broken seal recuts once.
Summary
Scenario 1851 is logistics dual-SIM for election ballot chain-of-custody — not CIT cash, not medical oxygen, not hospital linen, not specimen couriers. Vault packed is a hint. Seal-scan at the clerk dock is the join. Service pricing is devices plus SMS send volume. You bring the phones and operator credit. Free is 1 device, 300 SMS lifetime, and 300 contacts.
Starter allows 2 devices: vault plus courier. Uncapped platform volume is not unlimited carrier SMS. Confirm payloads in Developer Center.

run + seal — broken seal recuts once
A ballot drop is not a GOTV blast
Received copy names the precinct and pouch. Campaign merch lives elsewhere. Mixing them is how a clerk STOPs the week the only run they waited on is actually at the dock.
If vault fires “delivered” when pouches leave storage, ops thinks the clerk signed. Join seal-scan. Suppress packed-to-precinct templates.
Ballot dual-SIM matrix
| Event | SIM | Failure |
|---|---|---|
| Vault packed | Warehouse | “Received” before seal |
| Seal-scan | Courier | GOTV stuffed in |
| Broken seal | Courier once | Two received texts |
| Staff OTP | Auth pool | OTP on courier radios |
Seal-scan vs vault packed
Persist run-id plus seal-scan. DLR. MCP wraps REST only.
Route copy is not auto-reply
The SMS is that run. A GOTV newsletter is marketing. FTC business guidance is not a reason to hide pouch ID behind a vote-tomorrow pitch.
Devices, volume, and airtime
Election weeks spike. We meter devices and platform sends. Free (1/300/300) is one vault proof.
Chain operations
Charge courier chassis before first run. Setup, Downloads, pricing.
Decision guide
Ship when notice joins seal-scan. Delay if packed texts “received.” Not a CodeCanyon election pack.
Ballot checklist
- Run plus seal idempotency.
- Vault silent as received.
- GOTV off courier purpose.
- OTP off courier SIMs.
- Developer Center fields confirmed.
