SMS, answered
What is the difference between bulk SMS and an SMS API?
Bulk SMS sends one campaign to many numbers from a dashboard, which suits promotions and announcements. The SMS API lets your own software trigger texts programmatically, making it the right fit for OTPs, alerts and high-volume transactional flows that fire on their own.
What is an SMS gateway?
An SMS gateway is the bridge between your software and the mobile networks — it takes a message from your code or dashboard and delivers it to handsets over carrier routes. Telinfy’s gateway connects directly to operators worldwide, so your SMS goes out fast and reliably.
What is A2P SMS?
A2P (application-to-person) SMS is business messaging sent from software to a person — OTPs, alerts, reminders and campaigns — as opposed to person-to-person texting. Telinfy is built for A2P at scale, with the routing, sender IDs and compliance enterprises need.
How do I choose a bulk SMS provider?
Look for direct carrier routes (not grey routes), transparent delivery reporting, a real REST API and SDKs, local sender-ID and compliance support in your markets, and two-way messaging. Telinfy covers all of these with one global API and per-market compliance.
Which countries can I send SMS to?
Telinfy connects directly to mobile operators across 190+ countries, so you run domestic and international A2P SMS from one account — each message routed on carrier-grade infrastructure for its destination, with local sender-ID and compliance handled per market.
How do you handle sender IDs and regulatory compliance?
We register sender IDs and templates and apply consent and opt-out per market — US 10DLC, UK PECR, India DLT and global STOP handling — so your traffic stays compliant and delivers cleanly everywhere you send.
How fast do OTP messages arrive?
OTPs travel on a dedicated priority route and typically reach the handset within seconds. That speed keeps sign-ups, logins and payment confirmations moving instead of timing out.
Can I send personalised messages to each recipient?
Yes. Drop in merge fields like name, order number or appointment time, and Telinfy fills each message individually, so every recipient gets a tailored text even across millions of sends.
How do I integrate the SMS API with my systems?
Use our REST API or SDKs to send from any language, and subscribe to webhooks for real-time delivery status. Most teams wire up their CRM, store or app backend and start sending within a day.
How do I track whether messages were delivered?
Every message returns a live status of sent, delivered, failed or clicked, visible in the dashboard and pushed to your systems via webhooks. That lets you measure performance and retry or reroute wherever needed.
