Key Takeaways
- Scenario 1320 is a tattoo-shop OTP: the stall stays locked until the client’s digits land. Not groomer kennels, bridal fittings, or massage rooms.
- A code that sits behind a flash-sale blast is an artist staring at an empty chair and a stencil drying out.
- Do not SMS the stencil ID or aftercare notes. OTP + ticket only.
- Promo stays on another device so the priority queue is not starved.
- 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 1320 is a tattoo desk. Stalls are booked in 90-minute blocks. The curtain stays shut until OTP digits land. Groomer kennel OTP is the wrong list.

Booth OTP, not kennel
One priority send, one booking ticket. Map the digits to the stall lock, not a pickup gate.
If the flash-sale blast went first, the OTP sat in queue and the stencil dried on the table.
