I'm sure there is that kind of information, but it may not be the case that ModemManager or libqmi expose it (yet). We'd need to figure out what SIM file has the right information.

However, whenever I try to do what you mention I find similar issues. What I experiment is that I am only able to connect using the SIM I have introduced in the first place. It does not matter if I make a reboot, that will be the SIM with which I will be able to connect no matter I try to use it in first place or second (like if the modem stored some APN/connection info) I will make some more tests but it seems it may be a Modem issue. -- Kind regards, Alejandro Vega ___ ModemManager-devel mailing list ModemManager-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/modemmanager-devel

As you said, this should have been automatic. There's no state stored in MM that would affect this IF you did a full host system reboot OR a full modem reset. In both those cases, any state associated with the earlier exposed modem would have gone. To me this looks like a problem with the actual SIM card. Have you tried to start with that 2nd SIM card first, and switch to the original one to see what happens? -- Aleksander https://aleksander.es ___ ModemManager-devel mailing list ModemManager-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/modemmanager-devel
Issues registering in network when changing from one operator to another
Hello! I am developing an application making use of libmm-glib high level API and I am using a EM7455 Sierra Wireless modem. The modem is working under MBIM mode (usb-composition). I believe the issue I am experiencing is related to the *change of operator / SIM card*. The scenario is the following: 1. The first SIM card I introduce is able to register in the network and connect using the APN I specify in order to establish a connection. 2. I tell the modem to change the SIM card via internal AT command and I perform a system reboot (just to ensure everything starts fresh) 3. After the reboot and after waiting some time (>5-10 minutes) the Modem is not able to register in any network and the signal quality is never updated. Modem remains as shown * * * Status | lock: sim-pin2 | unlock retries: sim-pin (3), sim-pin2 (3), sim-puk (10), sim-puk2 (10) |state: enabled | power state: on | signal quality: 0% (cached)* *---* and it never transitions to a "registered" state, which I understand should be automatic. I have tried the following commands in order to force the network registration mmcli -m 0 --3gpp-scan --> OK mmcli -m 0 --3gpp-register-in-operator=x --> Returns: " error: couldn't register the modem: 'Timeout was reached' " My questions are: - Should signal quality be retrieved independent of the register state? Does it depend on the modem registration status ? - Is there any *connection related configuration* that either the *modem device or the ModemManager may be storing* ? If this would be the case, how could this information be erased? - Is there any way to ensure that the modem connection / register parameters are reset to factory default ? Thank you very much, any help will be appreciated. -- Kind regards, Alejandro Vega ___ ModemManager-devel mailing list ModemManager-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/modemmanager-devel
