FAQ

Bulk SMS questions

The basics, in plain language.

What is DLT registration and do I need it?

Yes. DLT (Distributed Ledger Technology) registration is required by TRAI for every business that sends SMS in India. You register your business, your sender ID and your message templates on an operator's DLT portal. We guide you through it.

How long does it take to start sending?

It depends mostly on DLT approvals for your business, sender ID and templates, which usually take a few working days. Once approved, we can set up your account quickly.

Can I send SMS in Hindi?

Yes. Hindi and other Indian languages are sent as Unicode SMS, where one SMS holds up to 70 characters instead of 160.

What's the difference between promotional and transactional SMS?

Promotional SMS are for offers and marketing - they only reach non-DND numbers between 10 am and 9 pm. Transactional and service SMS are for updates customers expect, like OTPs, reminders and alerts, and can be sent any time.

Is WhatsApp better than SMS?

They suit different jobs. WhatsApp allows images, buttons and two-way chat; SMS works on every phone without internet. Many businesses use SMS for OTPs and alerts, and WhatsApp for richer updates.
