How can I enable cell broadcast messages on Xperia M/why can't I install cellbroadcast.apk file?

[szist82]

Hello everyone,

My problem is that I can't see any opinion for receiving cell broadcast/emergency alert messages on my Xperia M.
I didn't find any settings relating for this function neither at Messages -> Settings nor General settings menu.
I downloaded cellbroadcast.apk and enabled to install any apps in settings, security but there was an error during install:
"Application not installed"
What's the problem with it? I know it is a minor and hardly used function but I'd like to add it. There are some phones which have this function.
Should my phone be rooted ?
How can I enable receiving cell broadcast messages? Or how can I install this app? There must be a way toactivate this function. Thank you for your answer.

Steve

If it didn't come from the Play Store, you need to go to Settings -> Security -> Unknown sources and enable prior to installing.

PS: Are you certain the capability isn't already installed? What version of Android OS are you running?

Of course, I enabled installing from unknown sources. I checked everything in settings, I don’t have any apps similar to this
Evenmore, in tge message settings, there are only sms, mms, and push settings, no signs for 'cell broadcast'
I guess this problem isn't easy solved.
I have Android 4.3
