Frequently Asked Questions
What is Bulk SMS and how does it work?
Bulk SMS is a service that lets businesses send large volumes of text messages to customers simultaneously through an SMS gateway, instead of sending messages one at a time from a phone. It's used for OTPs, order updates, promotional offers, and appointment reminders, and is delivered instantly to any mobile number — no internet or app required on the recipient's end.
Is Bulk SMS legal in India without DLT registration?
No. TRAI (Telecom Regulatory Authority of India) requires every business sending commercial SMS to register as an entity on the DLT (Distributed Ledger Technology) platform, along with their sender header and message templates, before sending any bulk SMS. Sending without DLT registration results in blocked messages. TechtoNetworks handles the full DLT registration process for clients.
What's the difference between transactional SMS and promotional SMS?
Transactional SMS covers OTPs, order confirmations, and account alerts, and can be sent to any number, including DND (Do Not Disturb) registered numbers, since it's not marketing content. Promotional SMS covers offers and marketing messages, can only be sent to non-DND numbers, and is restricted to specific time windows (9 AM–9 PM) under TRAI's TCCCPR regulations.
How much does Bulk SMS cost in India?
Bulk SMS pricing in India is typically charged per message and varies by message type (transactional, promotional, OTP) and sender volume, generally ranging from a fraction of a rupee to a few rupees per message depending on route and volume slabs. Pricing usually drops at higher volume tiers. See our pricing page for current rates.
What is an SMS Gateway API?
An SMS Gateway API is a set of REST endpoints that let developers integrate bulk SMS sending directly into their own website, app, or CRM — so messages like OTPs or order alerts can be triggered automatically by your own systems rather than sent manually through a dashboard.
Can I send Unicode SMS in regional Indian languages?
Yes. Unicode SMS support allows sending messages in Hindi, Malayalam, Tamil, and other regional scripts, though Unicode messages have a shorter character limit per SMS segment (70 characters) compared to standard English SMS (160 characters).
What is SMS header registration and why is it required?
An SMS header (or sender ID) is the 6-character code (e.g., "TECHTO") that appears as the sender name on a text message. TRAI requires all headers to be registered on the DLT platform and linked to a verified business entity before they can be used to send messages.
Do you offer an SMS reseller panel?
Yes. TechtoNetworks offers a white-label SMS reseller panel that lets agencies and resellers sell bulk SMS services under their own brand, with their own pricing and client management, while we handle the backend delivery infrastructure.
How fast is Bulk SMS delivery?
With Tier-1 carrier routing, bulk SMS is typically delivered within seconds, not minutes — critical for time-sensitive use cases like OTPs and flash sale alerts.
What is the WhatsApp Business API?
The WhatsApp Business API is Meta's official platform for medium and large businesses to send and receive WhatsApp messages at scale — covering notifications, customer support, and marketing — with features like automated replies, chatbots, and multi-agent support that aren't available on the regular WhatsApp Business app.
How do I get a WhatsApp Business API for my company?
You need to apply through a Solution Provider like TechtoNetworks, which handles Meta business verification, phone number registration, and message template approval on your behalf. Since businesses can't access the API directly from Meta, this onboarding typically takes a few days once documents are submitted.
How much does the WhatsApp Business API cost in India?
WhatsApp Business API pricing has two layers: Meta's official per-message rate (which varies by message category — marketing, utility, authentication — and recipient country) plus your BSP's platform fee. As of the current pricing model, businesses are billed per delivered template message rather than a flat conversation fee, so costs scale with message category and country.
What's the difference between WhatsApp Business App and WhatsApp Business API?
The WhatsApp Business App is a free mobile app suited for small businesses handling a low volume of chats from a single device. The WhatsApp Business API is built for scale — it supports automation, chatbots, CRM integration, multiple agents responding simultaneously, and programmatic sending, making it suited for businesses handling hundreds or thousands of conversations.
What is a WhatsApp message template and why does it need approval?
A template is a pre-written, pre-approved message format (e.g., an order confirmation or OTP message) that businesses use to initiate conversations with customers outside the 24-hour customer service window. Meta reviews and approves every template to ensure it isn't misleading, spammy, or promotional when categorized as a non-marketing template.
Can I send WhatsApp OTPs through the Business API?
Yes. Authentication-category templates are specifically designed for OTPs and verification codes, and typically carry the lowest per-message rate compared to marketing or utility templates.
What is the difference between WhatsApp marketing, utility, and authentication messages?
Marketing templates are promotional in nature and carry the highest per-message rate. Utility templates relate to a specific transaction or account update (like a delivery update). Authentication templates are strictly for OTPs and verification. Each category has a different Meta rate, with authentication generally the cheapest and marketing the most expensive.
Is WhatsApp Business API good for customer support?
Yes — it's one of its strongest use cases. Multi-agent inboxes, automated FAQ chatbots, and quick-reply buttons let support teams handle high message volumes efficiently, and customer-initiated conversations within the 24-hour service window don't incur template charges.
Can I do WhatsApp marketing and automation together?
Yes. Businesses commonly combine WhatsApp marketing campaigns (broadcast offers via approved marketing templates) with automation (chatbot flows, abandoned cart reminders, order tracking) using the same API connection.
What is WhatsApp Commerce?
WhatsApp Commerce refers to features like product catalogs, cart, and in-chat checkout that let customers browse and purchase products directly inside a WhatsApp conversation, without leaving the app.
Do I need Meta Business verification to use the WhatsApp API?
Yes. Meta requires business verification (confirming your company's legal identity and ownership of the phone number/domain) before granting access to the WhatsApp Business API, which your BSP manages as part of onboarding.
What is RCS messaging?
RCS (Rich Communication Services) is the modern replacement for SMS, built into Android's default messaging app. It supports rich media like images, carousels, quick-reply buttons, read receipts, and typing indicators — while still working through the phone's native messaging app rather than a separate app like WhatsApp.
What is RCS Business Messaging (RBM)?
RCS Business Messaging (RBM) is Google's platform that lets brands send verified, interactive RCS messages to customers — appearing with a verified business name, logo, and branded color in the recipient's default messaging app, similar to how a verified WhatsApp Business account appears.
How is RCS different from Bulk SMS?
Bulk SMS is plain text with strict character limits and no rich media. RCS supports images, carousels, suggested actions, and buttons within the same native messaging app, making it more interactive and visually engaging — while still not requiring the recipient to install any separate app.
How is RCS different from WhatsApp Business API?
RCS messages appear in the phone's default (Android) messaging app and don't require the recipient to have WhatsApp installed, while WhatsApp Business API messages only reach users who have WhatsApp. RCS currently has more limited reach on iOS compared to WhatsApp's cross-platform availability.
Does RCS work on iPhone?
RCS support on iOS has expanded through Apple's adoption of the RCS Universal Profile, though feature availability and Google RCS Business Messaging support can vary by carrier and region compared to Android. Reach on Android remains the most consistent.
What are RCS campaigns used for?
RCS campaigns are commonly used for rich product showcases (image carousels), interactive customer surveys with quick-reply buttons, appointment confirmations, and branded promotional messages that need more visual engagement than plain SMS allows.
Is RCS Business Messaging pricing similar to WhatsApp API pricing?
RCS Business Messaging is also billed per message, with rates varying by message type and region, similar in structure to WhatsApp's per-message model, though exact rate cards differ by provider and Google's current pricing framework.
Should I use Bulk SMS, WhatsApp Business API, or RCS for my business?
It depends on your use case: use Bulk SMS for guaranteed universal reach and time-critical alerts like OTPs (works on any phone, no app needed); use WhatsApp Business API for rich, two-way customer engagement and support where your audience is active on WhatsApp; use RCS for visually engaging campaigns to Android users without needing a separate app installed. Most businesses use a combination of all three for different message types.
Can I use Bulk SMS, WhatsApp, and RCS through a single platform?
Yes. TechtoNetworks provides a unified platform where Bulk SMS, WhatsApp Business API, and Google RCS can all be managed, sent, and tracked from the same dashboard and API, so you don't need separate vendor relationships for each channel.
What is a Business Solution Provider (BSP) and why do I need one?
A BSP is a company officially authorized by Meta (for WhatsApp) or Google (for RCS) to provide businesses access to their messaging APIs, along with onboarding, compliance, and support. Since neither Meta nor Google grants API access directly to individual businesses, a BSP is required to get set up and stay compliant.
Do these services require ongoing compliance monitoring?
Yes. TRAI's DLT regulations for SMS, Meta's WhatsApp policy updates, and Google's RCS guidelines all change periodically, and templates or accounts can be blocked or flagged for non-compliance. TechtoNetworks monitors these changes for clients and adjusts templates and sender configurations proactively.
What industries use Bulk SMS, WhatsApp API, and RCS the most?
Retail and e-commerce (order updates, flash sales), healthcare (appointment reminders, report sharing), banking and fintech (OTPs, fraud alerts), and education (student and parent updates) are among the heaviest users of all three channels in India.
Is there a free trial available?
Yes — a free developer sandbox account is available to test the Bulk SMS API before committing to a paid plan. WhatsApp Business API and RCS onboarding typically require business verification first, but demo access can be arranged.
