TRAI COMPLIANCE & DLT REGULATION

How to Register & Whitelist Short URLs for SMS on DLT Portals

Under telecom directives by the Telecom Regulatory Authority of India (TRAI), all hyperlinks, call-to-action (CTA) links, and tracked file attachments sent in SMS messages must be pre-whitelisted through your registered Principal Entity (PE) account on your telecom operator's DLT portal.

🛡️

Why TRAI Enforces Strict Short URL Whitelisting in India

To combat phishing and smishing scams, Indian telecom operators automatically filter and block any SMS containing unregistered URLs. Senders are prohibited from using arbitrary public URL shorteners unless the link clearly proves an official relationship with the sender brand. Whitelisting your domain ensures your document attachment links pass telecom AI firewalls with a 99.95% delivery SLA.

5-Step Process to Whitelist Short URLs on DLT Portals

Step-by-step workflow for Airtel DLT, Jio DLT, Vodafone Idea (Vi Vilpower), Smartping, and BSNL DLT portals.

01 PORTAL LOGIN

Log In to DLT Portal

Log in to your registered Principal Entity (PE) account on Airtel, Jio, Vi Vilpower, Smartping, or BSNL DLT.

Branded Short Domains vs. Generic Third-Party Shorteners

Understanding TRAI restrictions on arbitrary URL shorteners to prevent carrier filtering and message dropping.

RECOMMENDED & APPROVED TRAI Compliant

Branded Short Domain

Custom short domain explicitly identifying your brand entity (e.g., https://go.yourbrand.in/offer or https://0tp.in/XXXXXX/AXXXXXX).

  • ✓ Clear Sender Identity: The shortened URL clearly establishes a verifiable relationship with your registered business.
  • ✓ DLT Whitelisting Eligible: Approved across Airtel, Jio, Vi, and BSNL Principal Entity whitelisting modules.
  • ✓ High Recipient Trust: Users tap branded links with confidence, driving click-through rates up to 40%+.
  • ✓ 99.95% Delivery SLA: Bypasses telecom carrier spam scrubbing firewalls without packet loss or blocking.
Example: "Download your invoice: https://0tp.in/XXXXXX/AXXXXXX - SMSINDIAHUB"
RESTRICTED / BLOCKED High Risk

Generic Third-Party Shorteners

Arbitrary public link shorteners (e.g., https://bit.ly/abc123, tinyurl.com/xyz).

  • ✕ Zero Sender Verification: Arbitrary short links conceal the true destination domain, violating TRAI safety directives.
  • ✕ Carrier-Level Dropping: Telecom access providers flag and drop outbound traffic carrying non-whitelisted generic shorteners.
  • ✕ Low Recipient CTR: Smart mobile users hesitate to click obfuscated links due to rampant mobile fraud awareness.
  • ✕ DLT Sender ID Suspension: Repeated violations of URL whitelisting norms can lead to telecom blacklisting of your PE account.
Prohibited: "Click here for offer: bit.ly/3xY7k9z" (Blocked by telco firewalls)

SMS ATTACHMENT KNOWLEDGE BASE

Frequently Asked Questions About Sending Attachments via SMS

Authoritative answers on file limits, TRAI link whitelisting, dynamic variable personalization, and real-time click tracking.

1. How does sending file attachments via SMS work in India if SMS only supports plain text?
Standard telecom SMS networks (GSM 03.38 / 3GPP standards) transmit 160 characters of plain text and do not natively support binary media. SMSINDIAHUB solves this by uploading your documents (PDFs, Excel sheets, videos, images) to secure, high-speed CDN cloud storage. Our system automatically generates an ultra-short, TRAI-whitelisted trackable link (such as https://0tp.in/XXXXXX/AXXXXXX) and appends it to your text template. When recipients click the link, the document opens immediately in their mobile browser without requiring any special application.
2. What file formats and maximum file sizes are supported for SMS attachments?
SMSINDIAHUB supports all popular enterprise file extensions, including Document formats (.pdf, .docx, .txt), Spreadsheets (.xlsx, .xls, .csv), Presentations (.pptx, .ppsx), Images (.png, .jpg, .jpeg, .svg, .gif), Audio (.mp3, .wav), and Video clips (.mp4, .mpeg). The maximum recommended file size per attachment upload is 10 MB, ensuring ultra-fast download and smooth rendering across all mobile devices and network speeds.
3. How does adding an attachment affect the 160-character SMS limit?
Standard SMS has a character limit of 160 characters for GSM-7 plain text. Our intelligent link compressor shortens attachment URLs down to only 20 to 25 characters, leaving approximately 135 to 140 characters available for your custom message body. This ensures your complete message with the attachment link fits neatly within a single SMS credit without triggering multi-part message splits or additional billing.
4. Can I use short URLs in SMS, and how do I whitelist them on the DLT portal?
Yes. Under TRAI regulations, any short URL used in SMS must be whitelisted on your telecom operator DLT portal (Airtel, Jio, Vi Vilpower, Smartping, BSNL) under your registered Principal Entity (PE) account. Log in to your DLT portal, navigate to the CTA Whitelisting or URL Whitelisting section, submit https://0tp.in as your approved domain along with your sample tracking format (https://0tp.in/XXXXXX/AXXXXXX), and wait for telecom approval. In your DLT Content Template, incorporate the registered short link pattern with a variable placeholder (e.g., https://0tp.in/{#var#}) to ensure all outbound messages pass carrier AI scrubbing filters with a 99.95% delivery SLA.
5. Do I need TRAI DLT approval to send URL links or attachments in SMS?
Yes. Under the TRAI Telecom Commercial Communications Customer Preference Regulations (TCCCPR), all hyperlinks, short URLs, and file attachment web addresses sent in commercial or transactional SMS must be pre-whitelisted on your DLT portal (e.g., Jio, Airtel, Vodafone Idea, Smartping). Furthermore, your DLT message template must contain a designated URL variable placeholder (e.g., {#var#}) to ensure carriers do not block your outbound messages.
6. Can I send personalized PDF attachments, like invoices or marks sheets, to different customers?
Yes. SMSINDIAHUB allows you to send unique, dynamic attachments per recipient. Through our REST API or bulk Excel upload, you can map individual PDF URLs (such as invoice receipts, policy documents, account statements, or ticket vouchers) to corresponding recipient phone numbers. Each recipient receives a distinct tracked link specifically pointing to their personalized document.
7. What is the difference between an SMS delivery report (DLR) and attachment click tracking?
A standard SMS delivery report (DLR) confirms telecom network transmission—acknowledging that the text message successfully reached the recipient's handset. Attachment click tracking goes a step further: it captures engagement when the recipient actually taps the short link.
8. What is the delivery speed and SLA for attachment SMS campaigns?
SMSINDIAHUB delivers commercial and transactional messages with an average latency of 5 seconds and a 99.95% delivery SLA. Our direct telecom interconnects and intelligent dynamic multi-operator routing ensure instant link delivery across all major telecom circles in India.
9. Are there additional file storage or hosting fees for uploading SMS attachments?
No. SMSINDIAHUB includes cloud file hosting, link compression, and click analytics completely free of charge. You only pay for standard SMS text credits. There are no setup fees, hidden hosting costs, or bandwidth charges for uploaded documents.
10. Can recipients open attachments without installing third-party apps?
Yes. All attachments open seamlessly in the native mobile web browser (Chrome, Safari, Firefox, Edge) of the user's smartphone or tablet. PDFs and images display directly on-screen, while spreadsheets or documents can be viewed or downloaded with a single tap.
11. How can I track which specific mobile numbers clicked my attachment link?
You can monitor click activity in real-time through the SMSINDIAHUB web portal dashboard or receive immediate webhooks sent directly to your server CRM. You can filter and download detailed CSV reports containing the recipient's phone number, data to immediately follow up with high-intent leads.
