I recently inserted a second SIM card into my Aqua Fish and observed afterwards, that the symbol representing the signal strength in the status bar turned from white to red (which is the color of my ambience). Also, the name of the provider on the lockscreen changed from white to color.
This left me curious what this actually means, but I did not manage to find any information about this. I first guessed that it may have to do with the mobile data connection, which was disabled with my old SIM card, but even when I disable it the symbol remains colored. Does somebody knows what this is supposed to mean?
Thank you already.
