Notification sound when phone loses mobile signal

[papashaun]

My phone gives a notification sound when loses / gains mobile signal - does anyone know where the settings are to turn this off ?

( Is driving me crazy in some places eg local garden centre where the signal is flaky and as I walk round the phone continuously looses / finds signal and beeps every few seconds ! )

@papashaun: Next time you hear the notification, please head to Settings > Notifications > Recently sent, and check to see if any apps or features are listed here that correspond with the time you were notified. If you think you've found the culprit, tap on the relevant app/feature and explore your available options from here.
