Key Takeaways
- Scenario 690 is lease-renewal SMS: T-60 / T-30 / T-7 holds for the named tenant — not viewings, closings, or listing drips.
- A vacate or signed renewal must delete outstanding holds before a leftover “renew by Friday” fires.
- Do not put rent amounts or ID numbers in SMS 1. Portal or letter after identity.
- Owner portal OTP stays on another device. Promo “we have units” stays off this radio.
- 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 690 is a property manager running statutory or contractual renewal windows. The PMS knows the end date. The Android fires named-tenant reminders in the property timezone. The bug is a signed renewal at lunch and a T-7 “please renew” still sending at dusk.

Renewal clock, not a drip
Local notice rules are not optional because the CRM “always sends at 8.” Quiet hours still apply. Listing promo is a different MSISDN.
If the tenant already signed and the T-7 still fired, you trained them to ignore the next real notice — and you may have a compliance file.
