Use two-factor authentication to protect important Internet access points and logins from unauthorized access and hacking. The simplest form of two-factor authentication is to send transaction numbers (TANs) in the form of SMS text messages or voice messages. Today, everyone carries their cellphone with them at all times.
By the way, we also offer Pushtan solutions. Learn more about sending security codes via SMS from a concrete practical example.
Standing out from the competition
No matter where in the world you want to send mTANs: Via eCall your messages will find their destination reliably and at lightning speed. With our SMS gateway, we offer you a solution that is always one step ahead of the competition thanks to intelligent routing.
Have mTAN read out via a voice call
“High Privacy Voice” – Exclusive to eCall is the combination of sending mTANs via “Text-to-Speech” with the High Privacy security option: Our system reads the security code to the recipient. After processing, all contents are overwritten and can no longer be reconstructed or intercepted. This feature is the ideal addition for confidential to critical content, such as in the area of banking.
Standing out from the competition
Our Targeted SMS Routing function sets us apart from our competitors. eCall supports numerous SMS providers with various roaming partners. Routes can be optimized based on the destination number and selection of providers. This ensures consistent high quality in national and international traffic.
Special tool:

The tool enables you to send your SMS messages to their recipients’ cellphones using your own selected routes–– even messages destined for regions with less widespread coverage. Routing Finder sends text messages to your cellphone along various routes, with a dedicated security code as ID for each message. You receive a message and security code from every functioning route. Simply enter the security code in the tool to confirm your choice of route.
