I have the same issue. RMS device/ device details page do not refresh all data - especially mobile status even after updating information. It is not comfortable to clear cache after each use.
I have also proposal to include in "network/mobile/sim management"( I use RUT 950 ) same kind of condition for automatic switching depended of connection speed. Same operator, after drain assigned data limit do not cut connection, but radically decreases data transfer speed. In this case connection is unusable, but current SIM is on.
