The attached WWAN_UI.conf file can be used to enable the extra WAN settings (SIM card slot selection, Band selection, 2G/3G.4G selection, Roaming behaviour) if it is copied to the /storage/sdcard0 folder (does not work on sdcard1). My question is whether this file can be stored on the /enterprise folder (or sub-folder) so that it is in the same location as other config files?
