Transactional

OTP SMS

One-time passwords to the mobile number on the account — logins, fee payments, and password resets. Transactional routes, not promotional, so OTPs are not mixed with marketing traffic.

Transactional

Transactional SMS

Fee reminders, admission updates, order status, and appointment alerts to a parent or customer number. Uses registered headers and DLT templates so operators can deliver the message.

Campaigns

Promotional SMS

Campaigns to opted-in numbers for offers, events, and course batches. Separate from OTP traffic. We help with template wording that TRAI and DLT will accept — we do not send to purchased lists you cannot prove.

Integration

SMS API

Send from your school software, website, or app. You get credentials, sample calls, and delivery reports. Useful when NotesTime or a custom product already has the student or customer number.

Setup

DLT and sender setup

Entity registration, sender IDs (headers), and template filing so SMS can leave the operator. We walk your office through the portal instead of handing you a blank form.

Setup

Delivery reports

Sent, delivered, failed, and DND where the operator returns it. Finance can see what was billed. Failed OTPs get a retry path instead of a silent “sent” count.

How we work

  1. 1. Register

    DLT entity and SMS headers. We do not go live on traffic that will be filtered.

  2. 2. Integrate

    API or panel so your software sends to the mobile number. You keep the contact list.

  3. 3. Measure

    Delivery reports, failed OTP retries, and a named person in Sitamarhi or Patna when a header is blocked.

Who it is for

Schools, institutes, shops, and apps in Bihar that must reach a parent or customer on the phone inbox — fee reminders, OTP, admission updates, and order alerts.

Questions about SMS

Do you send SMS to a mobile number?

Yes. OTP, transactional alerts, and promotional campaigns go to Indian mobile numbers after DLT registration, sender ID, and approved templates. We do not send traffic operators will block.

Is this the same as WhatsApp?

No. This page is SMS to the phone inbox. WhatsApp Business API is a separate service. You can run both; many schools keep SMS for OTP and add WhatsApp for reminders.

Do you skip DLT?

No. Indian SMS needs entity registration, headers, and templates. We help you complete that so messages can actually arrive.

Can software fire the SMS?

Yes. API or panel access so your school software, website, or app sends OTP and alerts. You keep the customer list.
