Complaint Registered SMS Template for Internet Service Providers & Cable Operators

A ready-to-adapt SMS message for broadband ISPs and cable or DTH operators, with placeholders, sample values and compliance notes.

When to Send This Message

Send when a complaint is logged. For broadband ISPs and cable or DTH operators, this is one of the everyday messages that keeps subscribers informed without a phone call. Most businesses send it automatically from their software, so the timing is consistent.

Recharge reminders, outage updates and quick complaint resolution decide whether they renew or switch.

The SMS Template

India (DLT format)

Header: [6-character header]-S · Category: Service Implicit

Dear {#var#}, complaint {#var#} for ID {#var#} is registered with [Business Name]. Our technician will contact you by {#var#}.

International (plain text)

Dear {subscriber}, complaint {ticket} for ID {user_id} is registered with [Business Name]. Our technician will contact you by {eta}.

Example with sample values

Dear Mr. Dubey, complaint CMP-8812 for ID BB-55213 is registered with [Business Name]. Our technician will contact you by today 5 PM.

With these sample values the message is 135 characters in the standard GSM-7 character set, which is 1 SMS part (square brackets count as two characters each). Long links or local-language (Unicode) text increase the count, as Unicode SMS allow 70 characters per single part.

Replace [Business Name] with your registered brand name. Links shown use example.com as a placeholder; use your own domain.

Placeholders and Sample Values

Placeholder	Meaning	Sample value
{#var#}	Subscriber	Mr. Dubey
{#var#}	Ticket	CMP-8812
{#var#}	User id	BB-55213
{#var#}	Eta	today 5 PM

Filling in each placeholder

Subscriber (sample: Mr. Dubey): Use the first name or the salutation the customer gave you; fall back to a neutral greeting if the field is empty.
Ticket (sample: CMP-8812): Use the same reference format that appears on your invoices, receipts or software, so customers and staff can match it quickly.
User id (sample: BB-55213): Use the same reference format that appears on your invoices, receipts or software, so customers and staff can match it quickly.
Eta (sample: today 5 PM): Write dates in an unambiguous form such as 14 Oct or 14 Oct 2026; avoid formats like 10/11 that customers read differently.

This template has 4 placeholders and a body of 132 characters before values are filled in. Shorter messages cost less and are more likely to be read in full; aim to keep the filled-in message within one or two SMS parts.

Category and Approval

In India this type of message is usually registered as Service Implicit: it relates to an existing transaction or relationship and can be delivered to numbers on the DND registry. It must not contain promotional content.

Compliance Checklist

Promotional versions are sent only within the permitted hours and only to recipients who have not opted out.
The header (sender ID) and the template are registered on a DLT platform, and the template text matches exactly, apart from the variables.
Each {#var#} holds only the kind of value it was registered for; most platforms limit each variable to 30 characters.

Rules to keep in mind for Internet Service Providers & Cable Operators

ISPs are licensed under the Department of Telecommunications and must follow TRAI quality-of-service and consumer protection rules; advertised speeds should be stated as 'up to' with fair usage terms. Billing and outage messages are service messages, while upgrade offers need consent.

General guidance, not legal advice. Rules change, so confirm current requirements before launch. See our SMS compliance guide for India.

Tips for Better Results

Keep one purpose per message; if you need to send a reminder and a document, the reminder should still make sense on its own.
Use the customer's name and a reference number so the message is easy to trust and to search for later.

Where this message fits for Internet Service Providers & Cable Operators

Customers choose broadband based on coverage at their address, speed, price, contract length and reviews, then sign up online or by phone. Installation scheduling, outage updates and billing clarity shape satisfaction, and contract-end dates are when customers compare and switch.

Search and local ads drive sign-ups; address checkers on the website qualify leads; WhatsApp handles support chats; SMS sends installation slots, outage alerts and bill reminders; voice IVR routes support calls and reports known outages; email delivers bills and contract notices.

Questions About This Template

When should a ISP send the complaint registered message?

Send when a complaint is logged. Sending it at a consistent time builds trust and reduces follow-up calls.

What does {#var#} mean?

It marks the variable part of a DLT template, such as a name, date or amount. Everything outside the variables must be sent exactly as registered.

Which DLT category should I choose for this complaint registered message?

Usually Service Implicit. The final category depends on your entity type, the consent you hold and your operator's guidelines, and we confirm it during registration.

Can DND Teams set this up for my ISP?

Yes. We adapt the template to your business, register or submit it, and connect it to your software or our panel. Share your use case on WhatsApp or through the form.
