Key Takeaways
- Android SMS gateway API pricing is devices connected plus platform SMS send volume — not aggregator per-message credit packs.
- You bring the Android phone and operator SMS credit. We do not sell carrier airtime.
- Free tier is for proofs; paid plans start from $19/month with device meters.
- Starter/Pro/Business may uncap platform volume while devices still meter — do not market unmetered carrier SMS.
- Confirm live send fields in Developer Center.

Airtime is a third bar — on your operator bill.
Devices + volume, not per-message packs
The REST API does not sell “SMS credits” like a CPaaS wallet. It meters how many Androids you connect and how much you send through the control plane. Gateway model.
If your spreadsheet only has “API fee” and no “prepaid top-ups,” your unit economics are missing the radio.

Vs aggregator APIs
Aggregators rent numbers and usually bill per message. We meter devices + volume on your SIM. Comparisons. Messaging practices.
