Questions businesses ask us
What is an SMS gateway provider?
An SMS gateway provider is a company that connects your business to mobile operators so you can send SMS in bulk. It gives you a web panel or API, manages operator routes, checks DLT compliance and sends delivery reports. You use it for OTPs, alerts, reminders and marketing messages without building operator connections yourself.
How much does bulk SMS cost in India?
With us, bulk SMS costs ₹0.20 per SMS on Starter (up to 10,000 a month) and ₹0.15 per SMS on Business (up to 1,00,000 a month). Enterprise volumes get a custom price. All prices exclude 18% GST, and you are billed only for delivered SMS. DLT operator fees are paid separately.
Is DLT registration mandatory to send bulk SMS?
Yes. Under TRAI's TCCCPR 2018 rules, every business sending commercial SMS in India must register its entity, sender ID and message templates on an operator DLT portal. Messages that do not match a registered template are blocked by the operator. We help you complete the registration at no service charge.
How soon can I start sending SMS?
You can sign up and explore the panel the same day. Live sending to Indian numbers starts once your DLT entity, header and templates are approved, which usually takes 2 to 7 working days. If you already have DLT approval, you can share your IDs and start almost immediately.
Can I send SMS in Tamil, Hindi or other Indian languages?
Yes. Our platform supports Unicode SMS in Tamil, Hindi, Malayalam, Telugu, Kannada and other Indian scripts. Keep in mind that a Unicode SMS holds 70 characters per part, or 67 when the message is split, so a regional-language message may use more credits than the same text in English.
Can I send SMS to DND numbers?
Service, transactional and OTP messages can reach DND numbers at any time, as long as they use an approved DLT template. Promotional messages can go only to non-DND numbers or to people who gave you digital consent, and only between 10am and 9pm.
Do you have an SMS API for developers?
Yes. We offer HTTP and HTTPS REST APIs and an XML API. Each request carries your DLT entity ID, template ID and sender ID. You get a message ID in the response and delivery reports on your webhook. It works with PHP, Python, Node.js, Java and any system that can make a web request.
Do you also offer WhatsApp Business API and RCS?
Yes. AvanceZone is a Meta Tech Provider for WhatsApp. WhatsApp plans start at ₹999 a month with a one-time setup fee, and include templates, broadcasts and a shared inbox. RCS business messaging is also available, priced on request. You manage SMS, WhatsApp and RCS from one account.
Do you send SMS outside India?
Yes. Along with Indian SMS on DLT routes, we send SMS and WhatsApp messages to customers in the Gulf, South and Southeast Asia, the UK, the USA, Africa and many other countries. Each country has its own sender ID and consent rules, so we check them with you during onboarding. International SMS is quoted per destination in INR or USD.
SMS gateway providers in India: what to know before you buy
What does an SMS gateway provider do?
An SMS gateway is the software link between your business systems and the mobile networks. You send a message from a web panel, an Excel upload or an API call. The gateway checks it against your DLT records, passes it to the right operator and sends back a delivery report once the phone receives it.
An SMS gateway provider runs that link for you. It holds the operator connections, keeps the platform running day and night, stores your sender IDs and templates, and gives you billing and reports in one place. You decide what to say and who should get it. The provider takes care of getting it to the handset.
Most businesses use a gateway for three jobs. OTPs and login codes must arrive within seconds. Alerts such as order updates, fee reminders and EMI due dates must reach the right person every time. Campaigns such as festival offers must reach a large list at a fair cost. A good provider handles all three on separate, correctly registered templates.
Types of SMS routes in India
Indian operators put every commercial SMS into a category. The category decides who you can message and at what time. Since May 2025, a suffix at the end of the sender ID shows the category, so a reader sees AD-KOVAIM-S and knows it is a service message.
Picking the right category matters. If you put an offer inside a service template, the operator can reject it. If you send OTPs on a promotional route, they will not reach DND users and will stop at 9pm. Most businesses need at least one service header and one promotional header.
- Promotional (-P): offers and campaigns, sent only to non-DND numbers or people who gave digital consent, between 10am and 9pm.
- Service (-S): order updates, reminders, OTPs and account alerts for your own customers, allowed at any time with an approved template.
- Transactional (-T): alerts and OTPs of the kind banks send, allowed at any time, including to DND numbers.
- Government (-G): messages from government departments and bodies.
DLT in two minutes
Under TRAI's TCCCPR 2018 rules, every business that sends commercial SMS must register on an operator DLT portal. You register three things: your business as a Principal Entity, your 6-character header (sender ID) and each message template. One registration is shared across all operators, so you do it only once.
The operator charges about ₹5,900 including GST once for entity registration, and about ₹590 per header per year. Templates are free. Approval usually takes 2 to 7 working days. Since October 2024, every link or call-back number in an SMS must also be whitelisted, and public URL shorteners are blocked. Our team does this paperwork with you at no service charge.
How to choose an SMS gateway provider: a quick checklist
Before you sign up anywhere, check these points with the provider in writing. Then send a small test batch and compare the delivery report with what your own phones received. Be wary of offers that say no DLT is needed, or prices far below the market. Those routes tend to fail without warning.
- Direct connections to Jio, Airtel, Vi and BSNL, with backup routes if one fails.
- Billing on delivered SMS, with 18% GST shown separately on a proper invoice.
- Live delivery reports in the panel and through webhooks to your own system.
- A documented API that accepts DLT entity ID and template ID with every request.
- Hands-on help with DLT registration and template approval.
- A support team you can phone or WhatsApp during business hours.
