Key Takeaways
- API how to rotate devices for volume means pinning sends to a pool — not hammering one modem until OEM rate-ceilings bite.
- Do not rewrite the Android-app rotation how-to; that is physical swap. This is device ids in HTTPS/JSON.
- Live assignment fields live in Developer Center.
- Starter 2 / Professional 5 / Business 15. Rotation cannot invent a 16th radio.
- OTP stays on its own pool even when you rotate bulk.
- You bring every phone and every operator pack. We meter devices and platform send volume.
Rotation is routing, not magic throughput
API how to rotate devices for volume is how your backend spreads SMS across paired Androids so one OEM rate ceiling and one prepaid pack do not eat the campaign. It is device ids, weights, and health checks — not “unlimited send” by spinning SIMs.
API hub: Android SMS gateway API. Live fields: Developer Center. Multi-device product: multi-device and dual SIM.
“If the pool is three phones and one voucher, you rotated the invoice, not the radio.”
App rotation is a different spoke
Hot-swapping hardware, charging carts, and SIM KYC live on how to rotate devices (app). Link it. The API runbook assumes those phones are already paired and exempted.
What the API should pin
| Traffic | Rotation | Do not |
|---|---|---|
| OTP | Sticky pool, fail over on offline | Round-robin onto promo SIMs |
| Transactional alerts | Healthy devices, skip Doze | Retry storms without idempotency |
| Bulk | Weighted across funded SIMs | Dump the CSV on the OTP phone |
| Canary | Every device in the pool, daily | Canary only the “good” one |
| Dead device | Remove from pool immediately | Keep routing “for fairness” |
Offline: device offline KB. OEM ceilings: raise carefully; carrier fair-use still applies.
Device SKUs still cap you
Free and Developer: 1 device — there is nothing to rotate. Starter 2, Professional 5, Business 15. Unpairing to “share a slot” across sites is how you drop OTP. Pricing.
Do not rotate OTP onto promo SIMs
Priority queues and isolation beat clever weights. OTP priority queue.
Cost
Every extra radio is a device on the plan plus a voucher. Platform volume still meters. Free 300 lifetime / Developer 25,000 per year pause at allowance.
Checklist
- Health check before assign.
- OTP pool disjoint from bulk.
- Voucher per SIM named.
- SKU includes the spare.
- App rotation how-to linked for hardware.
