Services

SMSGatewayHub offers a range of business communication channels:

• Bulk SMS — transactional and promotional SMS for enterprises and marketers.
• OTP SMS — one-time-password delivery for login, verification and transactions.
• WhatsApp Business API — template and interactive messaging on WhatsApp.
• Voice — automated voice calls and IVR.
• RCS — Rich Communication Services messaging.
• Email — bulk and transactional email.

These channels can be integrated by developers through HTTP and REST APIs.

Technology and compliance

The service advertises message delivery in approximately 2–6 seconds and 99.9% platform uptime, and operates on a pay-per-delivered-message model. As an Indian A2P provider, SMSGatewayHub routes messages through operator connections registered under the TRAI-mandated DLT framework, which requires sender IDs (headers) and message templates to be pre-registered in order to curb spam and unregistered commercial messaging.

Use cases

A2P messaging platforms such as SMSGatewayHub are commonly used for OTP and two-factor authentication, order and delivery alerts, appointment reminders, payment confirmations, and marketing campaigns across sectors including e-commerce, banking and finance, healthcare, education and logistics.
