Key Takeaways
- Throughput on an Android SMS gateway is sustained sends per SIM over time — bounded by radio, OEM ceilings, and carrier fair-use.
- Raise OEM/Android rate ceilings carefully; do not claim carrier limits disappeared.
- Platform pricing is devices plus send volume. More devices raise capacity; airtime is still yours.
- Measure with canaries before promising OTP or bulk SLAs.
- Confirm live API fields in Developer Center.

You bring phones and operator credit. Devices and send volume.
msg / min · per SIM
Past the OEM mark, the radio pushes back.
Throughput is messages per time
Not theoretical API QPS. Sustained delivery on one SIM under Doze, RF, and operator policy. Bulk on phone gateway.
Throughput is what you can sustain on Tuesday afternoon — not what a burst script did once on a fresh Pixel.
What limits throughput
| Limiter | Symptom | Response |
|---|---|---|
| OEM SMS ceiling | Sends stall / errors | Raise documented ceilings |
| Carrier fair-use | Filtering / blocks | Pace + consent hygiene |
| Doze / OEM kill | Online but silent | Battery exceptions |
| Empty prepaid | Accepted then fail | Top-up ownership |
| Single device | Queue grows | Add devices; isolate OTP |
OEM ceilings ≠ carrier free-for-all
Prefer “raise OEM/Android SMS rate ceilings.” Never imply operator consent limits vanished. Doze.
Scale with devices
Rotate devices. DLR. Messaging practices.
Next steps
Measure one SIM for 15 minutes. Spend 300 lifetime SMS learning the ceiling — then size the fleet to peak, not average.
