Key Takeaways
- Scenario 1733 is a card travel-notice / “we see a foreign auth” CSV — not payroll, collections, KYC IDs, activation PINs, or dividend registers.
- Body is a yes/no confirm plus HTTPS. Never import CVV, full PAN, or OTP in the file.
- Step-up login stays on a dedicated Android. A holiday travel file will starve it.
- Priced by devices and SMS send volume. You use your own phone and operator SMS credit. Free is 1 / 300 / 300. Developer is 25,000 SMS per year.
- Corridor must match the licensed operator. A US SIM blasting EU MSISDNs is a filter event.
- REST send fields live in Developer Center — not a CodeCanyon “bank SMS” listing.
Summary

Your worker checks template id and E.164, then texts a confirm link. The Android is a radio, not the issuer host. Priced by devices and SMS send volume. You use your own phone and operator SMS credit.
