Got it set to automatic for networks and from what I am guessing it struggles between O2 3G and 2G - resulting in lost network completely - results in missed calls, lost texts etc - really annoying!</P><P>I did wonder originally if it was due to "stamina mode" in some way but really not sure what is going on tbh!</P><P>Not been with O2 before either so don't know whether this is normal&nbsp; but it is not as if I live out in the wilds somewhere!</P><P>&nbsp;</P><P>I have no doubt this is probably down to "operator error" but any help would be welcome</P> Sun, 19 May 2013 11:02:13 GMT https://community.o2.co.uk/t5/Android/Network-problem-for-Sony-Xperia-Z/m-p/470510#M18973 Anonymous 2013-05-19T11:02:13Z https://community.o2.co.uk/t5/Android/Network-problem-for-Sony-Xperia-Z/m-p/470608#M18980 Put your postcode into the coverage checker and see if there is an issue in your area<BR /><BR /><A href="http://www.status.o2.co.uk" target="_blank">www.status.o2.co.uk</A><BR /><BR />You could also try switching to 2g only when not using the data as the 2g signal is far better than the 3g.
