How to turn off cell broadcast in 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

Thank you
Go to Call Settings and uncheck "Broadcast" (homescreen -> phone -> settings -> broadcast).
