Key Takeaways
- Restaurant SMS KPIs are confirmation rate, no-show delta, and complaint/STOP — not a vanity “delivered %.”
- Reservation traffic and lunch-special blasts must not share the OTP SIM if you also do loyalty login.
- Measure on the same local operator your guests use. Cold handsets lie less than a busy manager’s phone.
- You bring the Android and operator credit. Device + volume is the gateway fee.
- STOP on promo. Two-way “YES/NO” on reservations needs the device online.
- Peak Friday 18:00 is a device-count problem, not a dashboard slogan.
What to measure (and what not to)
Android SMS gateway KPI measurement for restaurants is how you tell whether reminder texts actually seat people. A 99% DLR on a SIM path is not a cover. Guests who confirm and still no-show, or who never got the SMS because the shelf phone Doze’d, are different failures. Measure both.
You send through your Android and your operator airtime. We meter devices and platform SMS volume. Free is 300 SMS lifetime; Developer 25,000 per year. Starter / Professional / Business uncap platform volume and still cap devices (2 / 5 / 15). Friday night is a radio problem.
“If the only number on the GM slide is ‘messages sent,’ you are measuring the queue, not the dining room.”
KPI set for SMS on a restaurant SIM
| KPI | How to compute | Cadence |
|---|---|---|
| Confirmation rate | YES/clicks/replies ÷ reminders sent (same template) | Nightly |
| No-show delta | No-shows with reminder vs without (A/B by week, not by table) | Weekly |
| Canary RTT | Staff phone receive time before doors | Daily 16:00 |
| STOP / complaints | Promo list only — never on reservation OTP | Weekly |
| Airtime remaining | Prepaid voucher or postpaid cap | Daily |
Segment by device. A blended “restaurant SMS health” hides one dead SIM at the second site. Deliverability how-to.
Reservations vs promo vs OTP
Loyalty login OTP, “your table is ready,” and weekend brunch blasts are three lanes. OTP, auto-reply / STOP, bulk. Sharing a SIM trains guests to ignore the number that also asks for a 2FA code.
Service windows and quiet hours
Do not text confirmations at 23:40 because the batch job is naive UTC. Scheduled SMS (Starter and up) plus timezone in your app. Two-way YES/NO only works while the device is online — a lunch phone in a drawer is a missed cover.
Cost per seated guest
Attribute operator airtime + a slice of the device fee to seated covers, not to “SMS sent.” Retries on failed canaries still spend. We do not refund airtime. Pricing.
