Z Mobile signal problem

[YujiYuj]

Guys, i have observed thise problem for a week now and i wanna report here to see if anyone of you having the same issue.

My Xperia Z mobile signal (3G,LTE) is not fucntioning, sometimes i can see it is connected to 3G or LTE but no data flow. Sometimes it was just full bar on the mobile connectivity but without 3G or LTE. I have compared my Z to the other phone when this thing happened at the same time and the other phone seems to be ok. I off location WIFI all the time. Sometimes i restarted the phone then was ok.

I wonder if this is a phone or carrier problem, but my other phone is using the same carrier as well.

Please help. Thanks.
