I am experiencing signal drops with my Xperia U. It happens more so during travelling. As a result, I have to re-boot my phone at least 3-4 times a day.
Is anyone else experiencing the same problem?
do you have an old SIM card? contact your network/carrier about their coverage

Hi Uliwooly,
the SIM card is not a new one.. i'll contact my service provider for a new one and see if that works.
the coverage is ok.. i'm on this network for the past 9 years!
did u try switching the Network mode ???
Me and a friend of mine bought Xperia U together, and we both are facing the same issue. We got the software updated, which did not fix the issue. Then we got the phone itself replaced by sony service center, and even the new phone has exact same problem.
We tried another SIM card from same service provider, and no matter which SIM it is, phone is losing network signal and does not come back unless we reboot the phone. The same SIM cards are working just fine in other phones. We are kind of lost now, and planning to take this back to service center again. The original two phones plus the two new ones we got, we have seen this issue on all the Xperia U handsets we have seen!
Also we changed the network mode to GSM only, still no luck.
I had downloaded a free app from Google Play Store by the name 'Network Signal Speed Booster' by mcstealth. With this, i have seen slight improvement in the signal strength. I do see signal drops in the 'battery use' chart, but i think this app registers you back to the network. I no longer need to reboot the phone (as of now).
Do try if this helps for you as well.
I hope the Sony officials are listening to it and would bring some fix in the next software update.
Same problem with me too. I updated the software to 6.0.B.162 through sony suite & all the problem started.Got a new 64k SIM from my service provider still no luck. This is a big disappointment.
Sony officials please do something to solve the problem.
new update is up. wait for it.
I am also facing the same issue and I have to re-boot my phone at least 3-4 times a day eventhough GSM mode is selected. 
I gave my phone to the service center for replacement.
I request Sony Xperia Support people to kindly look into this issue as this is a major issue for any mobile phone.
I m also experiencing the same problem since the day i bought the phone..
Initially had thought it to be a sim card problem but now i realise it it aint..
What is the solution for this??
Will local sony support centre replace the device with a new one???
Pls somebody help me...
