Key Takeaways
- android sms gateway bulk csv import is a panel spreadsheet lane on Professional and Business — not a fake /api/send-bulk-sms, and not operator credits in a file.
- Map E.164, body/template, and consent timestamp before you press send. A missing country code is a silent skip or a wrong country.
- Suppress STOP numbers on import, not after the first thousand rows.
- Pace the resulting campaign to OEM ceilings and carrier fair-use. The CSV is instant; the radio is not.
- Priced by devices and SMS send volume. You use your own phone and operator SMS credit. Every accepted row still spends SIM airtime.
- API batches use to[] or POST /campaigns. This spoke is the spreadsheet path; do not rewrite the API cornerstone.
What bulk CSV import is
Search intent for android sms gateway bulk csv import is the Hub A spreadsheet path: upload a file, map columns, send through Android SIMs you host. Service pricing is based on device count and total SMS sent through the gateway. It is not a cloud SMS credit dump and not an invented bulk endpoint.
Product UI: bulk SMS from Excel and CSV. The thinner overview spoke stays on positioning; this page is mapping, consent, and radio pace. API cousins use to[] — see API for bulk SMS.
A CSV that imports in four seconds can still take all afternoon on one modem. Import speed is not send speed.
Which plans include it
Catalog: Excel/CSV import is Yes on Professional and Business, dash on Free, Starter, and Developer. Professional meters 5 devices. Platform send volume on those two paid SKUs is not capped like Developer; operator fair-use and airtime still apply. Numbers: pricing.
Column mapping that does not wreck a blast
Preview ten rows before the rest. If name merge is empty, the template must still read as a human sentence. Reject files with mixed country formats in one column unless you normalize first.
| Column | Rule | If you get it wrong |
|---|---|---|
| phone | E.164 with +; one number per row | Local 10-digit rows go to the wrong country or drop |
| body / template | Final text or a named template; no leftover {{tokens}} | Four thousand people get the merge syntax |
| consent_at / source | ISO timestamp + form/store id for marketing | You cannot defend the send |
| locale / timezone | Needed if you schedule quiet hours | 3 a.m. reminders, complaint spike |
| segment | OTP vs promo vs ops — never mixed in one campaign | STOP and 2FA collide on one SIM |
Consent columns are not optional
Import is not consent. Drop rows without a timestamp for marketing. Apply the suppression list before send — STOP from last week still counts. Workflow: auto-reply and STOP and bulk SMS use cases.
CTIA-style US consumer-line filtering punishes sudden volume. Ramp. Keep templates consistent. CTIA messaging positions.
Pace after import
Split the campaign: staff 10, then 5%, then remainder after DLR looks sane. Pin OTP to another device. Raise OEM rate ceilings where the phone allows — carrier caps remain. Failed retries still bill airtime.
Free canaries: 300 SMS lifetime. Do not “just see” a 2,000-row file on Free; it will pause when the allowance is exhausted.
Spintax and merge fields
Personalization helps filters less than people think, and broken tokens look amateur. Render a sample row in staging. Never put OTP codes in a CSV blast.
Import and send failure modes
- UTF-8 vs Excel CSV from a European locale — commas vs semicolons.
- Duplicate E.164 rows double-send without dedupe.
- One dry prepaid SIM halfway through the file.
- Webhook 500s so the CRM never records STOP mid-campaign.
- Uploading the OTP export into the promo mapper.
Launch checklist
- Plan is Professional or Business.
- E.164 sample of 10 delivered.
- Suppress list applied.
- OTP radios isolated.
- On-call owns airtime top-up.
- Rollback: pause campaign, do not re-upload the whole file.
Next steps
Map a ten-row file on a spare device from setup, then decide whether the panel lane or POST /campaigns fits the team. Field names: Developer Center.
