The latest news is that the configuration survives even the battery removal so it seems that it is stored either in the flash memory of the modem or in some configuration files though I wasn't able to locate the configuration files referred in the guide.
Indeed turning off and on the mobile data the context is activated and the mobile data signal strength icon goes from blue to gray with no other indication, I am sure that I had seen somewhere some settings for the icon but I can't recall it.
If for some reason the modem is off like in case you didn't enter the pin after booting the phone then do the following
ofonoctl poweron
ofonoctl online
qdbus --system org.ofono /quectelqmi_0 org.ofono.SimManager.EnterPin pin your_pin
Note that the modem may not always be /quectelqmi_0 but may be /quectelqmi_1, it will be printed after the ofono commands
I tried
qdbus --system org.ofono /quectelqmi_0 org.ofono.AllowedAccessPoints.GetAllowedAccessPoints
but it says that operation failed
A very interesting command is
qdbus --system org.ofono /quectelqmi_0 org.ofono.Modem.GetProperties
and the similar NetworkMonitor commands for getting information about your cell or the other cell around you
I also tried to set up the LTE because my operator gives me automatically UMTS data support but after getting the LTE properties again nothing changes like in the case of the context that it is populated with new parametres, maybe a new context is needed
qdbus --system org.ofono /quectelqmi_0 org.ofono.LongTermEvolution.GetProperties
qdbus --system org.ofono /quectelqmi_0 org.ofono.LongTermEvolution.SetProperty DefaultAccessPointName attach.telus.com
so now the Quectel beast is under control and there is much more research to be done with ofono and DBus
