Key Takeaways
- Localizing Laravel SMS is not wrapping __() around a 160-character English blast. Unicode can triple segments on the same SIM.
- Keep OTP numeric and boring. Translate receipts and alerts; do not poetically rewrite 2FA.
- There is no Laravel localization SDK from us. Lang files plus HTTPS JSON. Confirm fields in Developer Center.
- Honor STOP in the language you actually sent. A Bahasa body with English-only opt-out is a compliance hole.
- Priced by devices and SMS send volume. You use your own phone and operator SMS credit. Concatenated SMS still counts as more platform volume and more pulsa.
Language is a radio cost
Laravel / frameworks: how to localize message language on an Android SMS gateway is encoding plus consent, not a Google Translate job in the worker. Laravel send SMS. How an Android SMS gateway works. Laravel localization.
If the Bangla shipped-notice is three PDUs and finance modeled one, the locale launch is a billing incident.
GSM-7 vs Unicode
| Copy | Alphabet | Watch |
|---|---|---|
| OTP | Digits + short Latin app name | Stay GSM-7 when you can |
| Receipt / shipped | User locale | Segment count per language |
| Promo | Consented language only | STOP line in that language |
| Emoji “for warmth” | Often UCS2 | One glyph, many segments |
Laravel lang files, not string concat
The HTTP body is still REST — no SDK. Developer Center. CSV import should carry locale columns, not one English blob.
Ship locale without blowing segments
- Put copy in lang files, not in the job class. sms.otp, sms.shipped, sms.stop. Translators should not grep PHP.
- Budget segments per locale. English GSM-7 vs Bangla UCS2. Staff-canary both. Do not assume 160.
- Keep OTP templates tiny. App name + digits. No marketing footer on 2FA.
- Localize STOP / help lines. Same CLI, language the recipient can actually reply in.
- Do not auto-translate user-generated promo. Consent was for a language. Machine-translating a blast is how you get accidental spam wording.
- Canary each locale on a staff SIM. Render, count segments, confirm DLR. Then customers.
CTIA messaging principles. Ethics: spam-filter ethics— do not “localize” into filter evasion.
STOP has to make sense locally
If you send Indonesian, say how to opt out in Indonesian. Dual SIM does not give you two languages for free.
Extra segments still meter
Service pricing is based on device count and total SMS sent through the gateway. You need a working Android phone with a SIM and SMS credit from your mobile operator. Operator message costs are yours—we do not sell carrier SMS balance. Paid from $19/month; Free 300 SMS lifetime. Device and SMS volume pricing.
Next steps
Lang files, segment budget, local STOP, staff canary per locale. Then stop treating __() as a free SMS compressor.
