Both SIMs are always enabled (no way to disable one SIM)
"Receive incoming call while data is enabled" is always enabled
The QuickSettings tile will display the status for the currently selected SIM for data
There is no arrow activity indicator in the status bar.
Changing 2G/3G network mode using the QuickSettings toggle is not supported, only do it from Settings.
Changing 2G/3G mode in Settings may show too many options if the language used is not English. If more than 3 options is shown
only use the 3 top options (which will be WCDMA only/GSM only/WCDMA preferred regardless of the actual label shown).
Cannot set different ringtone for each SIM
