Key Takeaways
- Troubleshooting an Android phone as SMS gateway means radio triage: pairing, power, Doze, prepaid, queue — not only API errors.
- Link the phone-as-gateway hub; do not rewrite the overview.
- HTTP accepted ≠ delivered. Prove with DLR and a staff canary.
- A charged spare beats endless factory resets.
- You bring the Android and operator credit. Platform pricing is devices plus send volume.

Troubleshooting table
| Symptom | Likely layer | First move |
|---|---|---|
| Device offline | Pairing / network | Spare failover; Wi-Fi/data |
| Online, no send | Doze / OEM | Battery exceptions |
| Accepted, empty inbox | Radio / prepaid | Balance, signal, DLR |
| Queue climbing | Throughput | Pause promo; pace |
| 401 | API key | Env token — not factory reset |
Doze and OEM killers
Battery / Doze. OEM restrictions.
Fail over before deep dive
