Talking to your customers should be easy

Dexatel is a communications platform that lets businesses reach their customers by SMS, WhatsApp, Viber, Telegram, Voice, Flash Call, and Email through a single API.

It's used for user verification and OTP, alerts and reminders, marketing campaigns, and customer service messaging.

Founded in 2015, Dexatel serves both fast-growing businesses and hyperscalers, including TikTok and Alibaba, across more than 190 countries.

Self-serve customers can create an account, add funds, and begin testing without a sales call.

Many customers can send their first message on the same day, although some channels and countries require additional verification, sender registration, or compliance checks before live traffic can begin.

Dexatel uses transparent, pay-as-you-go pricing. You pay only for the messages you send, with no lock-in contracts and no per-feature fees.

Prices vary by channel, destination country, message type, and volume.

Some channels or countries may also involve third-party sender registration or monthly fees.

Dexatel delivers to more than 190 countries through direct and partner carrier routes, including hard-to-reach markets where standard routes often fail, such as China, Turkey, and Mexico.

Reliable delivery in these regions is a particular focus for authentication and high-volume messaging.

SMS, WhatsApp, Viber, Telegram, voice, email, and flash call, all through one API and one integration.

For verification, fallback is fully configurable, if a code fails, it's resent on the next channel in the sequence you set.

For campaigns and alerts, Viber messages fall back to SMS automatically.

Yes. Dexatel provides a Verify API for OTP and two-factor authentication across SMS, WhatsApp, Viber, Telegram, voice, and email.

Multi-channel fallback means if a code fails to deliver on one channel, it's sent on the next channel in the sequence you’ve configured, which raises verification success rates. Authentication is one of Dexatel's most common use cases.

Yes. Dexatel supports OTP delivery over WhatsApp, as well as SMS, Viber, Telegram, voice, and email.

Many businesses use WhatsApp as a primary or fallback channel for verification because it improves delivery in regions where SMS is unreliable.

With Dexatel's automatic fallback, if a code fails to deliver on one channel, it's sent on the next.

Yes. Dexatel supports high-volume authentication, notification, and messaging traffic for large digital platforms, mobile network operators, and other enterprise customers.

SMS works across standard mobile networks and is widely available on mobile phones. WhatsApp provides rich, verified business messaging within the WhatsApp app. Dexatel supports both channels so businesses can choose the best fit for each market and message type.

Dexatel works with fintech, iGaming, mobility, e-commerce, hospitality, and education businesses, as well as large digital platforms and mobile network operators.

It builds around specific vertical and regional needs rather than offering a one-size-fits-all template.
