Greetings MM, I'm excited to announce that T-Mobile US is now using ModemManager/libMBIM/libQMI for our 5G Fixed Wireless products [https://www.t-mobile.com/home-internet]. We are currently the largest FWA ISP in the world with well over 3 Million subscribers, i.e., lots of ModemManager users! We did this via an architectural contribution in partnership with the RDK community, a popular STB/Router Linux distro running on over 100 Million devices.
MM is now supported in RDK via a FOSS MM connection manager, CellularManager [ https://code.rdkcentral.com/r/plugins/gitiles/collaboration/rdkb/components/ opensource/ccsp/RdkCellularManager-MM/+/refs/heads/main] (need to signup for a free login), and is being worked on by dozens of major OEMs & ISPs. If anyone wants to provide feedback or reviews, please let me know. We're working hard to realize the full potential of this community by providing quality merge requests, via our partners & RDK, and guiding modem makers towards standards like QMI/MBIM. Please keep an eye out for us and our partners on the ML & Gitlab! Cheers, Matthew
