Way2SMS is a free, web‑based SMS gateway that lets users send bulk messages without a subscription fee. While the platform offers convenience, it lacks the built‑in compliance controls that professional SMS service providers (SSPs) provide. Consequently, users often embed “spam keywords” or unapproved content, leading to message blocking or account suspension.
What are spam keywords? These are words or phrases that trigger spam filters, either because they’re commonly used in unsolicited marketing (e.g., “free,” “click here,” “urgent”) or because they violate specific telecom guidelines. When a Way2SMS account sends a message containing such keywords, the telecom operator’s Distributed Ledger Technology (DLT) system flags it, preventing delivery and potentially marking the sender’s credentials as non‑compliant.
The Telecom Regulatory Authority of India (TRAI) is the apex regulator for all telecom services, including SMS. TRAI’s 2018 update to the Telecom Commercial Communications Customer Preference Regulations (TCCCPR) introduced a Blockchain‑based Distributed Ledger Technology (DLT) system that tracks every SMS sent in the country. The primary goals are:

All businesses sending bulk SMS in India must register on a DLT portal operated by a telecom operator (Airtel, Vodafone, or Jio). The registration process involves several key steps:
| Step | Description | Key Documents |
|---|---|---|
| Principal Entity (PE) Registration | Submit company details (PAN, GST, authorized signatory). | PAN, GST Certificate, Authorization Letter |
| Sender ID/Header Registration | Choose an alphanumeric sender ID (max 11 characters) that represents your brand. | Sender ID Application |
| Message Template Approval | Each SMS type (promotional, transactional, service) must be pre‑approved. | Template Submission |
| Consent Documentation | Record explicit opt‑in from recipients for promotional content. | Consent Forms, Opt‑in Records |
Without DLT registration, messages simply won’t be delivered. For instance, the Intex M Media guide confirms: “Without DLT registration, messages will not be delivered at all.”
Under TRAI rules, you can only send promotional SMS to recipients who have explicitly opted in. This means:
Failure to meet these requirements can lead to account suspension, as the DLT system flags non‑compliant messages.
India’s forthcoming Digital Personal Data Protection (DPDP) Act expands obligations beyond telecom. Key points include:
These privacy mandates reinforce the need for robust consent and data‑handling practices.
Every promotional or transactional SMS must match a pre‑approved template. Even a single character change—like adding an emoji, altering punctuation, or swapping a word—can trigger a compliance violation. The Intex M Media guide highlights that “Even minor changes can flag messages as non‑compliant.”
| Category | Example Keywords | Why They’re Problematic |
|---|---|---|
| Generic Spam | free, discount, offer, click here, urgent | Frequently used in unsolicited messages |
| Unverified Claims | guarantee, no risk, 100% | Can be seen as misleading |
| Phrases Triggering Filters | buy now, order, limited time | Often flagged by DLT systems |
When using Way2SMS, double‑check your content against your DLT template. If you’re unsure whether a keyword is problematic, consult your SSP’s compliance guidelines or the TRAI’s official list.
Promotional messages are only allowed between 9 AM and 9 PM local time. Sending outside these hours can result in immediate blocking. For example, the Fast2SMS compliance guide states: “Promotional SMS can only be sent between 9 AM and 9 PM.”
Recipients who have registered on the DND list cannot receive promotional SMS. Violating this rule leads to penalties and can trigger the DLT system to block your sender ID. Regularly sync your contact lists with the DND registry to avoid accidental infractions. (source: MessageCentral compliance blog)
Non‑compliance can be costly. TRAI imposes penalties that include:
These penalties are not just monetary—they can also damage brand trust and customer loyalty. A real‑world case: a mid‑size retailer’s Way2SMS account was blocked after sending 500 unsolicited messages containing “free” and “click here.” The retailer faced a ₹1.5 lakh fine and a two‑year suspension, costing them both revenue and reputation.

| Action | Why It Matters | How to Execute |
|---|---|---|
| Audit Existing Campaigns | Identify non‑compliant messages before they’re sent. | Run a compliance check on your last 100 SMS. |
| Build a Consent Management System | Demonstrates regulatory compliance and protects your brand. | Use an opt‑in platform that logs consent and allows easy opt‑out. |
| Set Up Automated DLT Checks | Prevents accidental policy violations. | Integrate your messaging API with DLT verification endpoints. |
| Create a DND List Maintenance Routine | Avoids costly penalties. | Schedule weekly updates to your DND list from the TRAI portal. |
| Train Your Marketing Team | Ensures everyone understands the rules. | Conduct quarterly compliance workshops. |
Navigating the legal and compliance landscape of SMS marketing—especially when using a platform like Way2SMS—requires diligence, transparency, and a proactive approach. By understanding TRAI’s DLT requirements, respecting consumer consent, avoiding spam keywords, and adhering to timing and DND regulations, you can safeguard your brand, avoid hefty penalties, and build lasting customer relationships.
