[feature request] SIM Indicator
When travelling abroad, I usually swap my SIM against a local one. But even at home, I use a different SIM every now and then, e.g. for testing or to try a new service. Furthermore, having multiple phones of the same type in a household, the SIM is the only differentiation.
It would be nice to have an indication, which SIM currently in the phone is.
Requirement: If this option is activated, a user defined string (suggestion: up to 3 characters), indicating the SIM currently active, should be displayed in the status bar. There should be an MMI option to assign a mnemonic to the currently active SIM. This creates a table IMSI -> SIM mnemonic stored on the device and allows to display a user defined mnemonic depending on the currently inserted SIM.
