I've never had a problem with hospitals here, just the usual asking that your phone be on silent/keep the noise down so as not to disturb others, though some wards ask you to turn off wifi/bluetooth so it doesn't interfere with other machines, maybe the hospitals there have a blanket ban for the same reason you can't use your phone on planes? XD

Also it would just be plain rude to be on your phone while you're supposed to be talking to someone else o_O
