Indian businesses often ask whether to invest in Bulk SMS or RCS Business Messaging. The short answer: many businesses use both, for different goals.
Side-by-Side Comparison
This table compares the two channels in general. What a specific provider offers, including SMSTAKE, depends on its platform and your account.
| Factor | Bulk SMS | RCS Business Messaging |
|---|---|---|
| Device reach | Almost all mobile phones, including basic phones | Only where the phone, messaging app and mobile network support RCS, and the business's RCS agent is launched |
| Content | Text. How much fits in one message depends on encoding; longer texts are sent as several segments | Images, video, rich cards, carousels, suggested replies and actions |
| Branding | A short DLT-approved sender header | Business name and logo; a verification mark only after brand verification and launch |
| OTPs | A common choice, because it reaches almost any phone | Usually not the primary channel, because reach is narrower |
| Campaigns | Broad reach with text | Rich creative on supported phones |
| Compliance | TRAI DLT registration, approved headers and templates | Google RBM and mobile network policies, brand verification and launch approval |
A Note on SMS Length
There's no single character limit for SMS. A message using only the standard GSM 7-bit alphabet fits up to 160 characters in one SMS, but a message containing Unicode characters - Hindi or another Indian script, many symbols, or an emoji - fits up to 70. Longer messages are split into segments that each carry a little less and are usually billed as separate messages. Our RCS guide explains encoding and segments in more detail.
When to Use Bulk SMS
- OTP and authentication flows
- Critical alerts that need the widest possible reach
- High-volume, text-only notifications
- Customers on basic phones, or on devices, apps or networks without RCS Business Messaging
When to Use RCS
- Product showcases with images and carousels
- Brand campaigns where visual identity matters
- Two-way conversations with suggested replies
- Abandoned cart recovery with rich CTAs
Using Both Channels
A common approach is to send RCS where it's supported and SMS to everyone else. Falling back from RCS to SMS isn't automatic in every setup: it has to be configured, usually as a separate DLT-approved SMS, and how it works depends on the provider.
SMSTAKE offers both Bulk SMS and RCS Business Messaging. Pricing, supported networks, delivery reporting and fallback options depend on your account and use case, and our team confirms them with you during onboarding.
