Key Takeaways
- An Android SMS gateway bulk campaign checklist is consent, STOP, E.164, isolated OTP SIMs, paced radios, and per-row keys — not a bigger CSV.
- Verify each row with a command or a canary, not a stand-up comment.
- OEM ceilings and carrier fair-use still apply. Raising Android SMS rate ceilings is not unlimited carrier send.
- You bring phones and operator credit. Pricing is devices plus send volume.

What “ready to blast” actually means
The list is opted-in, numbers parse, OTP still works during the send, and you can name who watches DLR. API production checklist.
A million-row file on one unpaid SIM is not a campaign. It is a prepaid funeral.
Bulk campaign checklist
| Item | Why | Verify |
|---|---|---|
| Consent + STOP | Legal + filters | Auto-reply / STOP |
| E.164 | No trunk-zero bombs | Number formats |
| Quiet hours | Local time, not server TZ | Schedule by timezone |
| OTP SIM isolated | Login SLA | deviceIds on campaign ≠ OTP |
| Peak radios | OEM + fair-use | Rate limits |
| Per-row keys | Worker restart | Idempotent send |
| DLR / webhooks | Know who got it | Webhooks |
| Airtime headroom | Prepaid death | Operator cost |
| Blacklist | STOP already in file | Blacklist |
Messaging practices: GSMA. Local law still wins.
