Key Takeaways

  • Scenario 1770 is a rent-stabilized recertification window SMS. A carrier slip is not a packet accepted — not utility meter-switch, dumpster day, or snag walk.
  • A clerk who stamps after “we sent” to an empty lobby is a wasted slot and a late-file fine.
  • Do not SMS income, SSN, or lease numbers. Desk, hours, and how to cancel.
  • Housing-portal OTP stays on another device.
  • Priced by devices and SMS send volume. You use your own phone and operator SMS credit. Free: 1 device / 300 SMS lifetime / 300 contacts. Developer: 25,000 SMS per year.

Android SMS gateway scenario 1770 is a housing-desk morning. Tenants get “recert 10:00–11:30, lobby B — bring last year’s packet.” T-18h DLR decides whether that slot stays reserved. Meter flips and dumpster crews are the wrong list.

Priced by devices and SMS send volume. You use your own phone and operator SMS credit. Scheduled SMS · Developer Center. GSMA.

Slip is not accepted. 09:40 undelivered list holds the stamp.

Recert, not a meter flip

Schedule T-18h window SMS. Map DLR to the unit id. 09:40 is an undelivered list, not a compliance pie.

If 22 were “sent” and 4 never delivered, you stamped four empty lobby chairs.
