Well, nothing is impossible, but I wouldn't try to do it that way. The current_sms_mem1_storage variable is part of the MMBroadbandModem logic, it doesn't apply out of it, it's only used as part of the logic doing the storage lock/unlock before R/W. Instead, what I would do, is to provide in MMBroadbandModemClass a new async virtual method to "load_current_sms_mem_storage()" (or something like that). The logic in MMBroadbandModem which checks which are the supported storages could then have a new step to query which is the current storage (which we only need to do once), all this in the MMBroadbandModem class. This class would then provide an implementation of the virtual method itself, not in the Telit plugin, as the change shouldn't affect other implementations and actually kind of makes sense. If we see that the change affects other modems, we can later just move the implementation of the virtual method to the Telit plugin and leave the generic MMBroadbandModem with the virtual method pointers to NULL so that other plugins don't use that logic.
