Heavy lifting, done

From establishing direct links with carriers to reduce latency, to making real-time decisions when networks present problems — you can rely on us.

  • More security, lower latency

    Normally an SMS goes through multiple hops before reaching its destination, increasing latency. We’ve fixed this problem — and heightened security — by building our own direct-to-carrier network.

  • Better delivery rates

    Carrier networks can be volatile — which is why our patented Adaptive Routing™ algorithm redirect traffic via the fastest and most secure alternative route. It’s like GPS for SMS.

  • Free inbound SMS*

    Receive SMSs for free and tap into the world’s largest inventory of SMS-enabled numbers in real time, through our API.

Minimize regulation hassles

We manage all the regulatory requirements around the globe, so you don’t have to spend time programmatically enforcing them for each country.

Enjoy elastic capacity

We have ultra-high throughput, allowing you to send up to 2.5 million messages per day - that's 30 a second - with virtually no upper limit.

Manage costs

Control your spend to expensive destinations through our Real Time Cost reconciliation to ensure you'll never run out of credits.

Analyze your traffic

Get real time analytics through our dashboard, and check volume, cost and destinations - all broken down by carrier network, quality of delivery and success ratios.

Receive delivery statuses

We return detailed status information about messages being delivered so you can measure quality of delivery & performance. And if your message failed to deliver, we give you a detailed breakdown of why.

Auto-split long texts

No need to split your messages in your logic. We take care of it for both outbound and inbound messages. But if you prefer to do it yourself, you can.

Bi-directional Unicode support

We support Unicode for both outbound and inbound messaging to make sure your message is delivered just as you intended, in the language of your choice.

Switch with SMPP support

Switch in seconds and get the full set of GSM capabilities, so no matter how specialized your needs are, we can support them.

Brand your messages

Use your brand name to send messages around the world, wherever it’s supported.
