Xperia U network issue

[#1]

Hello

I have recently 16 days before purchased Xperia U.

I am facing network issue with my new phone.

Every day at least once my phone does not show any network (Red cross displayed on network signal)

I need to power off and again power on to get network.

I am really dis-appointed with this issue.

Let me know if any one has faced this issue and has resolution to it

Hi
I am using xperia u from last 1 year twice is gone for repairs because of this no Network signals.When you speak to online support they alwaya tell you to do repair through PC CAMPANION OR SUS.
Today morning again I spoke to online support they said my phone needs repairs.
I have sent an email to sony today that sony think people dont have anything else to do in there life just to send phone for repairs after every 2 months.Car manufacturer recall car if they found any problems but here nobody wants to listen to us. I am waiting for there reply.
