Usernames and passwords aren’t enough to protect your access!
The current list of most common passwords is topped by *123456*, *password*, and *12345678*… That’s why you should protect important online accounts and logins from unauthorized access by hackers using two-factor authentication.
The simplest way to do this is by sending security codes via SMS to mobile phones. Learn more here about sending security codes via SMS using a real-world example.

Our mTAN solution and OTP delivery: A step ahead of the competition – worldwide!
No matter where in the world you want to send mTANs with eCall, your messages reach their destination reliably and in a flash. That’s why we offer a solution via our SMS gateway that stays one step ahead of the competition thanks to intelligent routing.
Have mTANs read aloud via a voice call
“High Privacy Voice” – Exclusive to eCall is the combination of mTAN delivery via “text-to-speech” with the High Privacy security option: Our system reads the security code aloud to the recipient. Furthermore, after processing, all content is overwritten and can no longer be reconstructed or intercepted. This feature is therefore the ideal complement for confidential to critical content, such as in the banking sector.
What Sets Us Apart from the Competition
Our targeted SMS routing sets us apart from the competition. eCall supports multiple SMS providers with various roaming partners. Furthermore, optimal routes can be selected based on the destination number and the choice of different providers. This ensures consistently high delivery quality both domestically and internationally.
Special Tool: SMS Routing Finder
Furthermore: With this tool, you can independently identify functional routes for SMS messages to your recipients’ mobile phones even if they are located in less accessible areas of the world. To do this, the SMS Routing Finder sends a text message containing a security code to your mobile phone via various routes. Every message you successfully receive confirms that this route is working. You then enter the identification code (security code) into the tool to confirm the route.
