Android SMS Gateway Scenario 199: Restaurants auto-reply and STOP in practice

Summary

Restaurant STOP in scenario 199 is catering and private events: planner guest files, load-in texts, “tray count confirmed,” and the post-gala upsell that must not resurrect someone who STOPped last month. This is not dinner-rush host-stand, franchise HQ weekly, or ghost-kitchen midnight. It is a banquet MSISDN that still owes inbound STOP.

Service pricing is devices plus SMS send volume. You supply the Android phone and operator SMS credit. Free is 1 device, 300 SMS lifetime, 300 contacts. Do not brand Unlimited SMS. Paid plans may uncap platform send volume; devices and carrier bills remain.

A planner CSV that ignores last gala’s STOP is not hospitality. It is a second text to someone who already asked you to stop — in a ballroom they paid for.

Key takeaways

• Catering and events STOP is a planner-list problem: the banquet file is not your weekly coupon CRM.
• “Tray count confirmed” can share a service SIM. Post-event upsell cannot share loyalty OTP.
• Quiet hours follow the venue, not the kitchen that prepped at 05:00.
• Service pricing is devices plus SMS send volume. You bring the phone and operator credit.
• Free is 1 device, 300 SMS lifetime, 300 contacts.
• Test STOP after the planner CSV lands, not only on a Tuesday lunch special.

Context

Events teams land here when a banquet guest muted load-in SMS and still got a Monday brunch blast from the same CLI. Quiet hours follow the venue. Tray-count confirms are operational. Post-event upsell is marketing. Loyalty OTP is isolated.

Core scenario guidance

Join planner files to event mute before send. HELP names the catering desk. Do not auto-reply into OTP. Staff-test STOP after every planner drop.

Overnight-test the events tablet. Confirm webhooks in Developer Center when mutes sync upstream.

Cost and ownership

Devices + volume + airtime. Every ACK is a send. Assign who tops up the catering SIM. Free (1 / 300 / 300) proves one event. A season of galas needs a device-and-volume plan.

Operations

Daily pairing, battery, unmatched keywords, “planner file applied?” After Android updates, replay STOP on a staff line. Spare handset charged. Events manager named.

Security and compliance

Rotate keys after the seasonal planner contractor leaves. STOP applies even when copy “feels like a reminder.” Do not log loyalty OTP bodies. Verify booking-widget webhook signatures.

Decision guide

Ship when planner join, event mute, and venue quiet hours exist. Delay if the tablet dies during load-in unexplained. If zero phone ops is mandatory, evaluate CPaaS for upsell and keep Android for local event numbers.

Checklist

• Planner import blocked without mute union.
• STOP proven after the drop.
• OTP isolated.
• HELP destination works.
• Spare paired.
• Events manager named.

Next steps

Read the server guide, compare device and SMS volume pricing, follow device setup, and confirm APIs in SMS API documentation.

Deep dive: production hardening

Auto-reply and STOP protect promotional lanes — never auto-reply into OTP threads. Event SMS still needs STOP when the copy is upsell. Battery exemptions dominate overnight prep. Contact lists need consent metadata. Document who owns SIM top-ups across venues.

Deep dive: scaling and failure modes

Multi-venue scale is more handsets and a stricter planner join, not a fake unlimited carrier pack. Scheduled SMS must survive device sleep. Dual-SIM “promo in slot B” fails after reboot. Never claim unlimited free cloud SMS credits with no device or volume meter.

Deep dive: integration discipline

Developer Center owns live API parameters. Planner webhooks must verify signatures before they trigger SMS. If zero phone ops is mandatory, evaluate CPaaS. Scenario playbooks still bill by devices and SMS send volume. You bring the Android phone and operator SMS credit.
