Plan Renewal Reminder 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 3 days and 1 day before expiry. For broadband ISPs and cable or DTH operators, this is one of the everyday messages that keeps subscribers informed without a phone call. It can be sent manually from a panel at first and automated later through an API.
Recharge reminders, outage updates and quick complaint resolution decide whether they renew or switch.
The SMS Template
India (DLT format)
Dear {#var#}, your {#var#} plan with [Business Name] (ID {#var#}) expires on {#var#}. Renew now to avoid disconnection: {#var#}International (plain text)
Dear {subscriber}, your {plan} plan with [Business Name] (ID {user_id}) expires on {date}. Renew now to avoid disconnection: {link}Example with sample values
Dear Mr. Dubey, your 100 Mbps plan with [Business Name] (ID BB-55213) expires on 20 Oct. Renew now to avoid disconnection: https://example.com/p/IS1
With these sample values the message is 150 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#} | Plan | 100 Mbps |
| {#var#} | User id | BB-55213 |
| {#var#} | Date | 20 Oct |
| {#var#} | Link | https://example.com/p/IS1 |
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.
- Plan (sample: 100 Mbps): Keep the value short and specific; test the longest realistic value to check the message still reads well.
- 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.
- Date (sample: 20 Oct): Write dates in an unambiguous form such as 14 Oct or 14 Oct 2026; avoid formats like 10/11 that customers read differently.
- Link (sample: https://example.com/p/IS1): Use your own short, recognisable domain; for SMS in India the domain must be whitelisted on DLT, and each variable is usually limited to 30 characters.
This template has 5 placeholders and a body of 131 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
- 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.
- Any link uses a domain whitelisted for your header, as TRAI requires for URLs in commercial SMS.
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
- Send it as close as possible to the event it relates to, such as right after booking or the day before an appointment.
- Keep one purpose per message; if you need to send a reminder and a document, the reminder should still make sense on its own.

Questions About This Template
When should a ISP send the plan renewal reminder message?
Send 3 days and 1 day before expiry. If customers reply, make sure someone on your team monitors and answers.
Can I send this SMS in India without DLT registration?
No. Commercial SMS in India must use a header and a content template registered on a DLT platform. Messages that do not match a registered template are blocked by the operator.
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.
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.
