移动：htc desire 816
I have been receiving about 50 flash sms a day, with my service provider name, from the number 50.
As I read here, it might be a issue with activating and deactivating cell broadcast on the phone. However, I could not find the path suggested for the deactivation (Setting/Call/Other Call Settings).
The option does not exist on this path. also it became an irritation for me. Whenever I am doing something with my device, that flash message popped up and I get interrupted.
To try deactivating this I have tried all possible steps (By blocking/deleting/stopping notification) but nothing worked out. Any ideas how to get rid of this?
Mobile: HTC Desire 816
Android Version: 4.4.2 with sense 6.0
Go to Call Settings and uncheck "Broadcast" (homescreen -> phone -> settings -> broadcast).
The simplest way to turn off broadcast messages on your HTC phone is - Remove sim card from HTC phone and insert the SIM to some other mobile (Samsung/Nokia) go to settings and turn off Cell broadcast messages, now remove the SIM card from your Samsung or Nokia phone and re-insert it in HTC phone. You should not get the CB messages anymore.
There are several ways to tackle this dilemma.
Long press the notification, tap on app info, now uncheck notifications (below force stop)

If rooted, using a file manager goto /system/app and either:
Rename cellbroadcastreceiver.apk with extension .bak
or Delete cellbroadcastreceiver.apk
If not rooted, using PC:
As with any change you make to your device, make a backup first
For HTC Desire, go to Messages > All Messages > tap 3 dots > Settings > Cell Broadcast > OFF.
