Ask us how WhatsApp reminders are set up for your clinic, or check your DPDP readiness.
Ask us on WhatsAppA clinic that has run SMS appointment reminders in India has almost certainly done a DLT registration, entity registration, sender ID, and every template filed and approved with a telecom operator before a message would go out. So when the same clinic moves reminders to WhatsApp, the question comes up automatically: do I need to register my WhatsApp templates for DLT too? As of August 2026, checked against TRAI's own regulation text and current reporting rather than a vendor blog's summary of it, the answer is no. WhatsApp Business API messaging is not part of TRAI's DLT framework. It runs under a separate compliance regime, Meta's own WhatsApp Business Policy, plus India's DPDP Act for how patient data is handled.
The confusion is reasonable. The two channels are regulated by different bodies under different laws.
DLT is TRAI's anti-spam mechanism for commercial communication over the telecom network.
DLT stands for Distributed Ledger Technology, the blockchain-style record TRAI uses to administer the Telecom Commercial Communications Customer Preference Regulations, 2018 (TCCCPR). It covers SMS and voice calls placed through telecom operators. The regime has been mandatory for commercial A2P (application-to-person) SMS since it was phased in from 2019, and TRAI has kept tightening it since, most recently with amendments in 2025 that standardised sender-ID headers and tightened consent rules further. A business sending commercial SMS or making commercial calls without completing DLT registration risks having those messages silently blocked by the telecom operator.
Meta's own WhatsApp Business Policy, built on three mechanisms.
That category split is Meta's pricing model for the WhatsApp Business Platform, a separate mechanism from TRAI's DLT template registration. India's DPDP Act 2023 governs how a clinic collects consent and handles patient data over any channel including WhatsApp, covered in full on CuraVerto's DPDPA post linked below.
WhatsApp still has a verification step, but it happens once, not per template.
The silent telecom block that DLT enforces on SMS does not apply to WhatsApp.
TRAI has an open consultation on OTT platforms. As of August 2026, it is a policy debate, not an enacted regulation.
No. CuraVerto's WhatsApp reminders, confirmations, and prescription delivery run on the official Meta WhatsApp Cloud API, which is governed by Meta's WhatsApp Business Policy and template approval, not TRAI's DLT framework. TRAI's DLT registration applies to commercial SMS and voice calls sent over India's telecom network under TCCCPR 2018, a separate regulatory regime that WhatsApp messaging is not currently part of. There is no DLT filing for a clinic to complete before sending WhatsApp reminders through CuraVerto.
DPDP compliance is a real, separate obligation from DLT, and it applies to WhatsApp the same way it applies to any channel a clinic uses to communicate with patients: consent, purpose limitation, and data-handling practices under India's DPDP Act 2023. CuraVerto's dedicated DPDPA post covers the eight binding obligations for clinics in full, including how WhatsApp fits into a clinic's consent and privacy notice.
Meta bills WhatsApp business-initiated template messages by category, fixed when the template is approved, not chosen per message. On CuraVerto, utility templates, reminders, confirmations and digital prescription delivery tied to something the patient already did, are metered at ₹0.15 per message. Marketing broadcasts, promotional content the clinic chooses to send outside a specific patient interaction, are metered at ₹0.88 per message. Neither rate has anything to do with TRAI's DLT registration, it is entirely Meta's own category pricing for the WhatsApp Business Platform.
Only if the clinic also sends commercial SMS or makes commercial voice calls over the telecom network, those channels remain governed by TRAI's TCCCPR and require DLT registration regardless of what messaging platform the clinic uses elsewhere. A clinic that runs its reminders, confirmations and prescriptions entirely through WhatsApp has no DLT obligation for that traffic.
It is a live policy question, not a settled one. TRAI has an open consultation process on regulating OTT communication platforms including WhatsApp, and telecom operators have pushed for it, but as of August 2026 no regulation has brought WhatsApp Business API messaging under TRAI's DLT framework. This reflects the current, verified position; clinics evaluating this long-term should treat it as current fact rather than a permanent guarantee.
CuraVerto connects clinics to the official Meta WhatsApp Cloud API, utility templates metered at ₹0.15 per message, no DLT registration, no third-party BSP layer, included from the Essential plan at ₹9,999 per year excluding GST.
