I have a RM502QAEAAR11A02M4G (firmware revision listed as well) and wanted to know if there is a newer firmware version available for this.
If not, then I need help understanding why when I enable QMI (as it is by default) I can not stay connected to my carrier (T-Mobile). It will connect, remain connected for ~15 seconds, and then disconnect. MBIM works OK, but I still experience intermittent disconnects, and it seems to cause other issues (like some phones can’t enable WiFi calling).
Thanks in advance!
