# Recharge reminder voicebot for telecom, DTH, broadband and subscriptions

A **recharge reminder voicebot** calls a customer a few days before their prepaid pack, DTH balance, broadband plan or subscription runs out, tells them the date, explains how to recharge through official channels, and logs what they said. Done well, it keeps customers from lapsing by accident. Done carelessly, it is exactly the kind of automated calling TRAI’s rules on consent, number series and robo-call disclosure are designed to stop. This guide covers both the call design and the rules.

By [Vocora team](https://vocora.in/about) · Published 19 October 2026

## Why recharge reminders are a big job in India

The numbers are large and most of them renew on a cycle:

- TRAI counted **1,312.25 million wireless subscribers** and **48.63 million wired broadband** connections at the end of August 2026.
- Pay DTH services had **48.56 million active subscribers** on 30 June 2026, down from 49.09 million in March, according to TRAI’s latest performance indicator report.
- **15.83 million** mobile users asked to port their number in August 2026 alone. A customer who lapses by accident is a customer a competitor can win.

Most reminders today go out as SMS. Many customers ignore them, or see them too late. A short, polite call to the accounts that matter most, followed by a WhatsApp message with the recharge link, is where a voicebot earns its place.

## What a recharge reminder voicebot does on the call

1. 01
   **Introduce** Says who is calling, on whose behalf, that it is an automated assistant, and why
2. 02
   **Inform** States the plan or pack, the expiry or suspension date, and what happens after it
3. 03
   **Route** Explains the official ways to recharge (app, website, retailer, payment link on WhatsApp)
4. 04
   **Handle replies**“Already paid”, “call later”, “change plan”, “cancel”, “stop calling”, each with a clear outcome
5. 05
   **Log and follow up** Writes the outcome to your CRM or billing system and suppresses further calls when needed

### A sample DTH reminder

Illustrative script, not a real customer call:

- **Bot:** “Namaste, main [operator] ki automated assistant bol rahi hoon. Aapke DTH account ka balance 21 October ko khatam ho raha hai. Kya aapke paas ek minute hai?”
- **Customer:** “Haan, maine kal hi recharge kiya tha.”
- **Bot:** “Thank you. Main isse check ke liye note kar rahi hoon. Agar payment update nahi hua hai, toh hamari team aapse contact karegi. Please kisi ko bhi OTP ya UPI PIN mat bataiye.”

Notice what the bot does not do: it does not argue, push an upgrade or ask for payment details. “Already paid” goes to a person to reconcile. An upgrade offer is a different, promotional call with different rules.

## Sector rules that shape the reminder

| Who sends it | Usual trigger | Rule to know |
| --- | --- | --- |
| Mobile prepaid (operators, distributors, recharge apps) | Pack or validity about to expire | Telecom Consumers Protection Regulations: special tariff voucher renewals need the customer’s explicit consent through a set process; the provider must send an SMS three days before each renewal is due |
| DTH and cable (operators, distributors, LCOs) | Prepaid balance about to run out | TRAI’s 2017 QoS regulations: 30-day prepaid billing cycle, validity declared in days; services can be suspended when balance runs out, and after three months of continuous suspension the subscriber can be deactivated |
| Broadband and fibre ISPs | Plan end date or unpaid renewal | General TRAI commercial communication rules (TCCCPR) for calls and SMS; your licence and plan terms for disconnection notices |
| Subscriptions with auto-pay (OTT, apps, memberships, AMCs) | Upcoming auto-debit or card expiry | RBI E-mandate Framework 2026: the issuer sends a pre-transaction notification at least 24 hours before the debit, and the customer can opt out of a transaction or the mandate |
| Subscriptions paid manually | Renewal date | TCCCPR for calls and SMS; Meta’s template rules for WhatsApp |

### Mobile packs: consent to renew is a defined process

TRAI’s Telecom Consumers Protection Regulations set out how a special tariff voucher is renewed after its validity ends. The provider tells the customer the details, terms and renewal charges, and the customer consents through a set route, such as a “yes” SMS to a toll-free number, an email or a button on a landing page. Consent logs are kept for six months, and after every renewal the provider sends an SMS three days before the next due date with the terms and how to deactivate. A voicebot can remind and explain; it should send the customer to that route rather than treat a spoken “yes” as consent.

### DTH: suspension, then deactivation

Under TRAI’s 2017 quality of service regulations for TV distribution, the prepaid billing cycle is 30 days, and since October 2024 prepaid validity must be declared in days. A distributor may suspend a prepaid subscriber whose balance runs out, and after three months of continuous suspension may treat them as inactive and deactivate them, with a capped reactivation fee on restoration. That gives a natural reminder schedule: before the balance runs out, on suspension, and once more before the three-month mark.

### Auto-pay subscriptions: the bank already notifies

RBI’s E-mandate Framework 2026 requires the card, PPI or UPI issuer to send a pre-transaction notification at least 24 hours before each recurring debit, with the merchant name, amount and date, and to let the customer opt out. Your own reminder should not duplicate that. Use calls for the cases where auto-pay failed or the card is about to expire.

## TRAI and DLT consent rules for reminder calls and SMS

The Telecom Commercial Communications Customer Preference Regulations (TCCCPR), 2018, as amended in February 2025, apply to any business sending commercial calls or SMS. The points that matter for recharge reminders:

- **Know the category.** Messages are promotional, service, transactional or government, and SMS headers now carry a -P, -S, -T or -G suffix. A plain reminder about a customer’s own plan is service; an offer to upgrade is promotional.
- **Implicit consent ends with the contract.** Consent for service and transactional messages lasts only for the duration of the contract. Once a customer has left, a “come back” call needs explicit consent.
- **Transaction consent lasts 7 days.** Consent given to complete an ongoing transaction is valid for only 7 days.
- **Opt-outs stick.** You cannot ask someone who opted out for consent again for 90 days.
- **Disclose automation.** The amendments bring in disclosure of auto-dialer and robo-call use, so the bot should say it is an automated assistant.
- **No ordinary 10-digit numbers.** Senders are restricted from using normal 10-digit numbers for telemarketing. Promotional calls use the 140 series; service and transactional calls move to the 1600 series for BFSI and government and to the 1601 series for other sectors. TRAI started the 1601 series with utilities, courier and logistics in August 2026. Telecom, DTH and broadband were not in Phase I, so ask your operator what applies to you now.
- **SMS goes through DLT.** Register as a principal entity, register your headers and content templates, and keep the template wording to what was approved. Our [DLT and 1600/1601 explainer](https://vocora.in/blog/dlt-registration-1600-series-explained) walks through it.

Pattern rules matter too. TRAI asks operators to flag senders with unusually high call volumes, short call durations and low incoming-to-outgoing ratios. A reminder campaign that dials every expiring account at 10 am and hangs up after eight seconds fits that pattern. Spread the calls out, cap attempts, and see [why business numbers show as spam](https://vocora.in/blog/business-number-showing-spam-india).

## WhatsApp reminders: Utility or Marketing?

Meta’s template rules draw a fine line here. Its Utility examples include an account alert such as “Reminder: your monthly payment for [service] will be billed on [date]”. But Meta also says Utility templates should not “attempt to secure renewals”, and lists “attempt to renew subscriptions” under Marketing, “even if requested by users”. Its own Marketing example is “Your subscription will expire on [date]! Renew today to save…”.

In practice:

- A factual auto-debit or billing notice with no offer is likely to be accepted as Utility.
- A “renew now” or “recharge now” push, especially with a discount, will be treated as Marketing.
- Meta decides the category and can re-categorise a template after approval.

Template examples are in [WhatsApp payment reminder templates](https://vocora.in/blog/whatsapp-payment-reminder-templates) and [30 WhatsApp template examples](https://vocora.in/blog/whatsapp-message-templates-examples).

## A reminder schedule that respects customers

A simple cadence most teams can start with, adjusted to your own data:

- **A few days before expiry:** SMS or WhatsApp with the date and recharge options.
- **A day or two before:** a voicebot call only for accounts that have not recharged and are worth a call.
- **On expiry or suspension:** one message saying what has stopped and how to restore it.
- **After that:** stop, unless the customer asked for a callback or is still under contract.

Cap call attempts per customer, call at reasonable hours, and honour “stop calling” the same day across every campaign.

## What to measure in a pilot

- Recharge or renewal before the expiry date, compared with a control group that got SMS only
- Connect rate and average call length
- Share of calls handed to a person, and why
- Opt-outs and complaints, which should stay close to zero

Judge it on your own numbers, not on a vendor’s headline.

## How Vocora runs recharge and renewal reminders

Vocora’s [Voice AI](https://vocora.in/voice-ai) places reminder calls in Hindi, English or Hinglish from a feed of expiring accounts, and [WhatsApp AI](https://vocora.in/whatsapp-ai) sends the follow-up with the recharge or payment link. Scripts are agreed with your team, number series and DLT set-up are checked with your operator before launch, and every outcome is written back to your system. The same approach powers our [EMI reminder voicebot](https://vocora.in/blog/loan-emi-reminder-voicebot) for lenders, and the [AI telecaller guide](https://vocora.in/blog/ai-telecaller-india) covers other outbound call types.

## FAQ

### What is a recharge reminder voicebot?

It is a voice AI agent that calls a prepaid or subscription customer shortly before their plan, pack or subscription runs out, tells them the expiry date, explains how to recharge or renew through official channels, and logs the outcome. Unlike a recorded robo-call, it can answer questions such as “I already paid” or “which plan am I on?” and hand over to a person.

### Is a recharge reminder call promotional or service under TRAI rules?

A reminder to a current customer about their own plan or subscription is generally service or transactional communication, where consent is implicit for as long as the contract lasts. Offers, upgrades and win-back calls are promotional and need explicit consent, a registered telemarketer and the 140 series. Confirm the classification of each call type with your operator before going live.

### Can we call customers whose subscription has already ended?

Be careful. TRAI’s February 2025 amendments say implicit consent for service and transactional communication lasts only for the duration of the contract. Once a customer has left, a call asking them to come back needs their explicit consent.

### Which number should recharge reminder calls come from?

Not an ordinary 10-digit mobile number. TRAI restricts their use for commercial communication. Promotional calls use the 140 series; service and transactional calls are moving to the 1600 series for BFSI and government and to the 1601 series for other sectors, starting with utilities, courier and logistics in August 2026. Ask your telecom operator which series applies to you today.

### Can a voicebot take a ‘yes’ on the call as consent to auto-renew a telecom pack?

For telecom special tariff vouchers, TRAI’s consumer protection regulations set out how renewal consent is taken (for example a ‘yes’ SMS to a toll-free number, email or a button on a landing page) and require consent logs to be kept for six months. A voicebot should point the customer to that process, not treat a spoken ‘haan’ as consent.

### Should the reminder go on WhatsApp instead of a call?

Use both, in that order of preference for most customers: WhatsApp or SMS first, a call for high-value or about-to-lapse accounts. On WhatsApp, Meta treats a plain account alert as Utility but classes messages that try to renew a subscription as Marketing, even if the user asked for them.

### Will the voicebot ask for card or UPI details?

It should not. A reminder call should send the customer to your app, website, retailer or a payment link, and never ask for an OTP, UPI PIN, CVV or card number. Say so on the call; it helps customers spot fraud.
