Our Story

Built in Chennai.
Trusted across India.

PING4SMS was founded in 2019 in Chennai with a straightforward mission: give Indian businesses a bulk SMS platform that's affordable, reliable, and honest.

We noticed that every SMS provider in India had one frustrating problem — credits expired. Businesses bought SMS credits, used what they needed, and lost the rest when the validity period ended. It felt like burning money.

So we built PING4SMS differently. Lifetime validity — credits you buy never expire, ever. We also added a free white label reseller panel (which competitors charged ₹15,000 for), real phone support in Tamil and English, and free DLT registration assistance.

Today, 50,000+ businesses across India use PING4SMS for Promotional SMS, Transactional SMS, OTP, WhatsApp API, Voice Call, and RCS messaging. From Chennai textile traders to Bangalore startups to Mumbai logistics companies — one platform handles it all.

Your SMS credits should never expire. That's our promise — and it hasn't changed since day one.

Mission & Vision

Why we exist and
where we're going

Our Mission

To make reliable business communication accessible to every Indian business — from a Chennai textile trader to a Bangalore startup — with honest pricing, lifetime credits, and real human support that answers when you call.

Our Vision

To be the most trusted communication platform for Indian businesses — where every SMS, WhatsApp message, and voice call is delivered reliably, and every rupee you invest in communication is always protected.

Our Values

What guides every
decision we make

No Expiry — Ever

Lifetime validity is not a feature. It's a value. Your money should never disappear because of an arbitrary expiry date.

Real Human Support

When you call 9003051520, a real person answers. In Tamil or English. No bots, no tickets, no waiting music.

Total Transparency

No hidden fees, no setup charges, no surprise deductions. What you see is exactly what you pay — nothing more.

Full Compliance

DLT compliant, TRAI approved, SSL secured. We handle the regulatory complexity so you can focus on your business.

Local First

We're a Chennai company. We understand Tamil Nadu businesses. We speak your language — literally and commercially.

Reliability Always

99.9% uptime on AWS. Your SMS campaigns, OTPs, and alerts — delivered every time, without exception.

What Makes Us Different

Features no other Indian
SMS provider offers

UNIQUE

Lifetime Validity Credits

No other major SMS provider in India offers lifetime validity. MSG91, Fast2SMS, TextLocal — all expire in 6–24 months. Ours never do.

UNIQUE

Free White Label Panel

A fully branded reseller panel at zero cost. Other providers charge ₹5,000–₹15,000 for this. Every PING4SMS customer gets it free.

UNIQUE

24/7 Phone Support

Call 9003051520 any time — a real expert answers in Tamil or English. Most providers offer only tickets, emails, or chatbots.

DND Auto-Refund

SMS to DND numbers are automatically refunded to your account — instantly, no manual request. Zero credits wasted.

Switched from another provider 2 years ago. Pricing is better, support is way faster — they actually pick up the phone! The free white label panel alone saved us ₹10,000 per year.
