About AvanceZone SMS: The Team Behind This Site

Who runs this site

SMS Gateway Providers is an SMS, WhatsApp and RCS messaging service operated by AvanceZone Technology. Our office is at #4, Kalangal Road, Sulur, Coimbatore, in Tamil Nadu. We started offering bulk SMS in 2000, back when businesses sent alerts from desktop software and dial-up connections.

Since then we have served more than 5,000 businesses. Our platform carries over 1 billion messages a year, connects directly to Jio, Airtel, Vi and BSNL, and targets 99.9% uptime. Companies that have worked with AvanceZone include Mindtree, GE Oil & Gas, Pricol, PSG College and GRT Hotels.

What we believe about AvanceZone SMS

Three ideas shape how we work. They come from two decades of watching what goes wrong for businesses that send SMS: surprise charges, blocked templates and support lines nobody answers.

• Transparent pricing: our per-SMS rates are published, GST is shown separately and you are billed on delivery.
• Compliance first: we help every client register correctly on DLT and follow TRAI and DPDP rules, even when it slows the first send.
• Human support: when something goes wrong, you can phone or WhatsApp a person in our Coimbatore office.

How we have changed with the rules

Indian SMS has changed a lot since 2000. DLT registration became mandatory under TRAI's TCCCPR 2018 rules. Operators began adding -P, -S, -T and -G suffixes to headers in May 2025, and only whitelisted links have been allowed in SMS since October 2024. The DPDP Act 2023 raised the bar on consent and opt-outs.

Each change meant updating our platform and walking clients through new steps. We added DLT fields to the API, template tools in the panel and opt-out handling for campaigns. We also added WhatsApp Business API and RCS, because many customers now expect to hear from businesses there too.

How this site relates to AvanceZone

This site is where we explain SMS gateways, DLT rules and pricing in plain language, and where businesses sign up for our messaging platform. Accounts, billing, support and DLT help are all handled by the AvanceZone team.

The guides here are written for business owners and developers who want straight answers. We avoid ranking or criticising other providers. We would rather give you a checklist and let you judge.

What we offer today

Our platform covers bulk, transactional and promotional SMS, OTP SMS, an SMS API, two-way SMS, international SMS, voice SMS, WhatsApp Business API and RCS. We also run a white-label reseller panel for agencies that want to sell SMS under their own brand.

Businesses connect us to their own tools through the API and webhooks, including Zoho, HubSpot, WooCommerce, Shopify, WordPress, Google Sheets, Zapier and Pabbly Connect. If you use something else, our team can usually suggest a simple way to link it.

Serving businesses in India and abroad

Most of our customers are in India, but many also sell, hire or support customers in other countries. We send SMS and WhatsApp messages to the Gulf, South and Southeast Asia, the UK, the USA, Africa and beyond from the same account, with delivery reports for every number.

Each country has its own rules for sender IDs, consent and sending hours. We check the current requirements with you during onboarding and help with registrations such as UAE and Saudi sender IDs, Singapore's SSIR and US 10DLC. International SMS is quoted per destination in INR or USD.
