Do you have a SIM in your phone?Does the same happen if you remove it?

I haven't seen this before. It sounds like a network message. Could you upload a screenshot of the notification?

I am having this exact same problem. I'm using a Sony Xperia Z running Android 4.4.2. Ever since updating, my phone has been so unreliable that I'm considering switching to my old one until an update comes out to mend the lovely additions of the last one.

I have used the fix for short battery life as provided in the Sony forums (disabling Google Play Services) so I'm not sure if it has anything to do with this. Today though, I have had about 50 (not exaggerating) notifactions from my phone that says "Restricted Access Changed - Voice Service Blocked." It comes for a few seconds, occasionally knocks out my reception and then leaves just as abruptly as it came. You can't press on the notification because if you do it just disappears. 

My current network mode is WCDMA (preferred)/GSM. I have also used LTE (preferred)/WCDMA/GSM and the problem occurs then as well. My phone bill is paid up so it definitely isn't an overdue bill or anything like that. In my not so professional opinion, I think it is a new and improved glitch from 4.4.2.

I've attached a screenshot as requested, any help at all would be greatly appreciated.

Thanks!

This message indicates that there's a problem with the network or your SIM card. I recommend that you first contact your operator to check if they are aware of any issue with the network in your area. If there's no network issue i recommend that you try the phone with another SIM card.

Hi All,

I too experienced similar issue and found the fix ...

The problem is not because of any upodate's. in Android 4.4 you need to select the your network service type, like GSM, WCDMA, LTE.....

Settings => Wireless & Networks => More => Mobile Networks => Network Mode.

Select the corresponding network mode and Select Network Operators and  choose your service provider...

That's All...

Now you can make call's as usual.....

Happy New Year...     Enjoy.......
