Key Takeaways
- Scenario 1853 is a card-activation / “your plastic shipped” CSV — not payroll, not collections, not KYC ID nags.
- Activation SMS is a portal link and last-four band. Never import PIN, CVV, or full PAN in the file.
- Issuer OTP and step-up stay on a dedicated Android. A 40k activation file will starve login.
- Priced by devices and SMS send volume. You use your own phone and operator SMS credit. Free is 1 / 300 / 300.
- Control totals vs cards issued. A 0.3% MSISDN shift is a complaint wave.
- Developer Center owns send fields. The issuer owns the template id.
Summary
Scenario 1853 is fintech bulk CSV for card activation notices. Ops drops a shipping extract. Your worker checks template id and E.164, then texts a short HTTPS activate link. The Android is a radio, not a PIN printer. Priced by devices and SMS send volume. You use your own phone and operator SMS credit.
