There are granular controls also in SK, but the messages themselves are not granular. The grades seem to be somewhat the same as in the US, so this might be set either at the GSM standard level or the device (Silent, Extreme, Sever, issing person, Public safety, test), but the senders do not care or have no control... A translation of my last EXTREME level warning from SK (before switching everything off as most citizens do): "A tropical night advisory is currently in effect. Please take precautions for safety, such as lowering indoor temperatures, staying well-hydrated before going to sleep, and calling the elderly to check on their well being." [Daejeon Metropolitan City] It was hot during the day (33C), but not THAT hot...
