Key Takeaways
- Scenario 1158 is Tuesday 11:15 appraisal SMS on the API path—not a Monday cron that Doze holds until 14:40.
- Store site timezone. A UTC dump texts owners at 05:15.
- Listing flyers and portal OTP never share the appraisal MSISDN.
- Service pricing is based on device count and total SMS sent through the gateway. You need a working Android phone with a SIM and SMS credit from your mobile operator. Operator message costs are yours—we do not sell carrier SMS balance.
- Professional is 39/month and meters 5 devices. Appraisal retries still spend operator credit.
- Canary the 11:15 template on staff numbers Monday afternoon.
Summary
android sms gateway api scenario 1158 is Tuesday 11:15 appraisal SMS—not a Monday cron that Doze holds until 14:40. Service pricing is based on device count and total SMS sent through the gateway. You need a working Android phone with a SIM and SMS credit from your mobile operator. Operator message costs are yours—we do not sell carrier SMS balance.
11:15 local appraisal ping. Store site timezone. Battery-exempt the modem.
An 11:15 lockbox code that lands at 14:40 is a Doze hold, not a late appraiser.
Appraisal ping
| Job | When | Failure | Lane |
|---|---|---|---|
| Appraisal ping | Tue 11:15 local | Doze / UTC | Access SIM |
| Portal OTP | On demand | Expire + reissue | Auth SIM |
| Listing flyer | Weeknight | STOP / consent | Promo lane |
Key takeaways
- Scenario 1158 is Tuesday 11:15 appraisal SMS on the API path—not a Monday cron that Doze holds until 14:40.
- Store site timezone. A UTC dump texts owners at 05:15.
- Listing flyers and portal OTP never share the appraisal MSISDN.
- Canary the 11:15 template on staff numbers Monday afternoon.

Context
Listing desks use scenario 1158 when Tuesday 11:15 appraisal SMS must fire in site time on the API path, not UTC.
Radio reality still wins: offline phones and OEM killers break scenarios overnight.
Cross-link hub cornerstones instead of rewriting the product overview.
Keep examples conceptual until Developer Center confirms live request shapes.
Budget airtime for retries — failed loops still cost operator credit.
Core scenario guidance
Store the listing timezone. Exempt the modem from Doze. Keep flyers and portal OTP off the appraisal MSISDN. Live send fields stay in Developer Center.
Separate configuration mistakes from radio failures during incidents.
Write acceptance criteria before seasonal or clinic-hour traffic.
Prefer gradual rollout with feature flags when automation is involved.
Cost and ownership
Plans are billed as device + SMS volume tiers—not aggregator-style $0.0x-per-message platform charging. Starter, Professional, and Business include unlimited platform send volume; Developer and Free have published SMS caps. Operator airtime remains separate, and carrier fair-use still applies. Professional is $39/month and meters 5 devices. Appraisal retries still spend operator credit.
Failed retries still burn credit during scenario experiments.
Assign who owns SIM top-ups and spare handsets.
Keep marketing spend out of OTP device pools.
Operations
A Monday 23:00 queue is fine only if the phone stays awake through 11:15 local Tuesday.
Daily checks: pairing health, battery, queue depth, and DLR anomalies.
After OEM updates or SIM swaps, re-test the scenario path end to end.
Keep a spare charged device ready for failover drills.
Name an on-call owner before unattended sends go live.
Security and compliance
Lockbox codes are still secrets. Do not log them in the brokerage Slack.
Protect API keys per environment; rotate after contractor access ends.
STOP and consent still apply on promotional scenario lanes.
Verify webhook signatures and TLS on every callback path.
Decision guide
Ship android sms gateway api scenario 1158 when owners, metrics, and fallbacks are written.
Delay if you cannot explain offline-phone behavior during peak hours.
If zero phone ops is mandatory, evaluate CPaaS for that lane.
If local SIM economics matter, harden the Android path and monitor airtime.
