Preferred PLMN list support in ModemManager

Hi, We seem to have need for a new feature in MM again: the ability to read and write the SIM card's preferred PLMN list (basically the equivalent of AT+CPOL functionality). If it looks feasible, we could contribute the code needed for this. In addition, for the preferred PLMN list to take

ModemManager 1.16

Hi, There are some new features in MM master branch that we would like to take in production use in the near future. Are there any plans or schedules for MM 1.16 stable version release, so that we could adjust our plans accordingly? Best regards, - Teijo

Detecting SIM REFRESH events

Hi, Earlier this year, I contributed a feature to detect (e)SIM profile switches on Quectel modems (commit d98597e43). In our use case, we'd like to extend profile switch detection to a larger selection of modems. In practice, this means detecting when a REFRESH proactive command is invoked by

QMI CID leaks

Hi, I'm working on a patch to detect M2M eUICC profile switches on Quectel modems. Upon testing with Quectel EG25, which uses QMI, I noticed that when MM reinitializes a modem (either due to hot-swap or MM restarting), some of the QMI CIDs don't appear to be released. After ~10 times, the
