<div dir="ltr">We've really been wanting to get it working better for our customers, but honestly your summary is true. Carriers aren't supporting hooks to reliably to get the information. I personally haven't seen a 3GPP command in the data sheets I have to get the info either. If that changes I'd be the first to bring it back but until then it's kind of a dead field.

It has been implemented only in the Altair LTE plugin, and the current implementation is based on two main things: * Verizon-specific logic that allows knowing the subscription state based on the PCO info. * Registration check errors, e.g. to say that the SIM is unprovisioned when the registration fails. I'm not sure any of the previous two things are very robust. The Verizon-specific parsing will only work for Verizon, and the registration check errors may be caused by multiple different root causes. To me it looks like the Altair LTE plugin is trying to do more than it's supposed to do. It would be much better if we exposed the raw PCO info received, and let upper layers process that if needed with operator-specific logic. What do you all think? Should we deprecate the SubscriptionState property? Should we expose the raw PCO info? -- Aleksander <a href="https://aleksander.es" rel="noreferrer" target="_blank">https://aleksander.es</a> _______________________________________________ ModemManager-devel mailing list <a href="mailto:ModemManager-devel@lists.freedesktop.org">ModemManager-devel@lists.freedesktop.org</a> <a href="https://lists.freedesktop.org/mailman/listinfo/modemmanager-devel" rel="noreferrer" target="_blank">https://lists.freedesktop.org/mailman/listinfo/modemmanager-devel</a> </blockquote></div> </div>
