Key Takeaways
- TypeScript bulk send loop for Android SMS gateway: typed HTTPS calls with delay — not an official multi-language npm SDK from us.
- Consent and STOP before bulk; isolate OTP device pools.
- Priced by devices and SMS send volume. You use your own phone and operator SMS credit. More devices raise peak; loops do not invent airtime.
- Free 300 SMS lifetime is the wrong budget for blasts.
- Idempotency-Key per logical recipient send.
- Developer Center owns live fields.
A TypeScript bulk send loop against an Android SMS gateway is paced HTTPS with types — read a row, POST { to, text }, backoff, continue. Related: Node bulk loop. Bulk SMS. TypeScript docs.

Bulk loop design
| Step | TypeScript does | Must include |
|---|---|---|
| Load batch | Typed rows / CSV | Consent flag |
| POST | fetch + JSON | Idempotency-Key |
| Handle | Narrow status unions | Backoff / halt |
| Pace | setTimeout / sleep | Per-device budget |
REST only — not an npm SDK product
Publish internal packages if you want — do not claim an official SMS Gateway TypeScript SDK. Same rule as PHP samples.
Pace for one radio
Add devices for peak — multi-device. Raise OEM ceilings carefully; carrier fair-use still applies.
Stop conditions
Auth fail, allowance exhausted, offline device → halt and alert. Do not hammer.
