Four checks for a India launch

Use this as an engineering handoff. Get a written carrier answer and qualified legal review where the call purpose or data handling requires it.

  1. 01

    Register the principal entity and campaign through the applicable DLT process.

  2. 02

    Classify service, transactional, and promotional calls before selecting a route.

  3. 03

    Verify the current 140 or 160 numbering-series requirement with the carrier.

  4. 04

    Run a paid pilot for every target language and telecom circle.

What still needs a carrier answer

Global CPaaS documentation is not a substitute for an India carrier and DLT approval. Confirm 140/160 series, CLI, and streaming support.
