What is the difference between OTP, transactional and promotional SMS?

OTP messages are commonly used for user verification. Transactional or service messages communicate account, order or operational information. Promotional messages are used for eligible marketing communication and are subject to applicable consent, preference and regulatory requirements.

Is DLT registration mandatory?

For SMS sent to Indian mobile numbers, businesses generally need the applicable Principal Entity registration, approved headers and content templates according to the message category and current regulatory requirements.

Can Vinayak help with DLT onboarding?

Vinayak can provide onboarding guidance and technical assistance for entity details, sender headers, templates and SMS account mapping. Final approval remains subject to the relevant operator platform.

Can the SMS API connect with my existing application?

Yes. Integration can be planned for websites, mobile applications, CRM, ERP, e-commerce platforms and custom software, subject to the supported API and agreed project scope.

Can I send SMS in Gujarati or Hindi?

Unicode messaging can support Gujarati, Hindi and other regional languages. Message length and credit consumption may differ from standard English SMS.

How is SMS pricing calculated?

Pricing can vary according to route, message type, volume, language, destination and integration requirements. Vinayak provides a tailored quotation after reviewing the requirement.

Where do existing customers log in?

Existing customers can access the SMS panel at sms.vinayakebiz.in.
