Key Takeaways

  • Localizing SMS on OSS GitHub stacks is GSM-7 vs UCS-2 math — not only string translation.
  • Keep OTP digits ASCII; Unicode wrappers often cost two segments.
  • Link the open-source hub; do not rewrite the overview.
  • Operator airtime is per segment; SaaS Free is 1 device / 300 SMS lifetime if you compare.
  • Canary every locale on real handsets.

Locale is encoding

Open-source GitHub how-tos on localizing message language still hit the radio: one non-GSM character can flip a 160-character OTP into UCS-2. Hub: open source.

“Translate the sentence, not the digits. Full-width numerals will fail the form.”

Your panel UI language ≠ recipient body. Put locale in the product. SaaS comparison: Android SMS gateway.

Canaries

Staff handset per script. Fail CI if OTP exceeds one segment without a flag.

Cost

Concat burns operator segments. Devices + volume on SaaS; Free 1/300 lifetime. Pricing.
