Whats about EC-GSM

hello everyone,
I am looking for an optimal LPWAN solution for my project. Everywhere we talk about NB-Iot and Cat M1. But what about EC-GSM-Iot? Do your modules support this technology? I have heard that the networks in Germany support this technology. Is that right? You don’t find so much on the Internet about this third cellular LPWAN.
I would be very happy about help.

Thank you,
