Why Global SMS Capability Matters (Most Providers Ignore This)

Many Mumbai providers focus only on:

• Local promotions

• Low-cost SMS

But modern businesses need:

• International OTP delivery

• Cross-border notifications

• Multi-country user onboarding

Siratel enables India + global SMS from a single dashboard and API—no multiple vendors, no routing confusion.

DLT Compliance in India

DLT is mandatory for SMS delivery in India.

DLT basics

• Sender IDs must be registered

• Message templates must be approved

• PE ID is required

Without DLT:

• Messages fail

• Delivery rates drop

• Routes may get blocked

Siratel assists businesses with end-to-end DLT onboarding and compliance, reducing delays and errors.

International SMS Compliance (Handled by Siratel)

Each country has its own messaging regulations.

Examples:

• UAE requires sender approvals

• Brazil enforces spam controls

• Germany requires opt-in compliance

Siratel manages:

• Country-level regulations

• Route approvals

• Content validation

So businesses can scale globally without regulatory headaches.

Delivery Speed and TPS – Why It Matters

TPS means Transactions Per Second. If your provider supports 500 TPS, it can send 500 messages per second.

Why TPS matters

• OTP delays break user logins

• Flash sales need instant reach

• High-traffic apps require stability

Siratel offers scalable TPS based on business volume.
