Compliance notes (India & US)<\/h2>\n\n\n\n
    \n
  • India (TRAI DLT):<\/strong> You (the sender) must register your Entity<\/strong>, Header<\/strong>, and Templates<\/strong> with an operator DLT portal (Airtel\/Jio\/VIL\/BSNL). Several vendors above provide DLT guides and mapping<\/strong> help. (, , , )<\/li>\n\n\n\n
  • US (10DLC):<\/strong> A2P SMS requires brand & campaign registration<\/strong> and per-carrier fees. Vendors supply fee tables and onboarding. ()<\/li>\n<\/ul>\n\n\n\n
    \n\n\n\n

    My recommendations (balanced for price, reliability, and developer experience)<\/h2>\n\n\n\n
      \n
    • Best overall (global, developer-friendly):<\/strong> Plivo<\/strong> and Telnyx<\/strong> \u2014 consistently lower per-SMS list pricing<\/strong> with straightforward APIs; great for OTP and alerts at scale. Use their Verify\/Number Lookup as needed. (, )<\/li>\n\n\n\n
    • Best enterprise reach & deliverability:<\/strong> Sinch<\/strong>, Infobip<\/strong>, Syniverse<\/strong>, Tata (Kaleyra)<\/strong> \u2014 deep operator ties and anti-fraud tooling; ideal for regulated and truly global footprints. (, , , )<\/li>\n\n\n\n
    • Best for India-first cost & DLT help:<\/strong> Exotel<\/strong> (public price from \u20b90.18\/SMS at 100k), 2Factor<\/strong> (SLA pay-per-delivered OTP), MSG91<\/strong>\/Gupshup<\/strong> (rich DLT resources). (, , , )<\/li>\n\n\n\n
    • Security-heavy OTP (fraud reduction):<\/strong> Telesign<\/strong> and Infobip (Signals)<\/strong> if you\u2019ve seen AIT\/pumping or high OTP failure\/retry costs. (, )<\/li>\n\n\n\n
    • If you want the fastest time-to-first-message and lots of SDKs:<\/strong> Twilio<\/strong> \u2014 not always the cheapest, but unmatched documentation and tooling (especially if you already use Twilio SendGrid\/Voice). ()<\/li>\n<\/ul>\n\n\n\n
