Since this upgrade we have almost completely lost our signel in our house. We have tried using TU GO but it is incredibly unreliable and we struggle to make calls. We are quite cross because we had both just upgraded our contract for another year and I am not sure we would have chosen o2 even though we have been with them for years had we known this would be the case. Feeling quite annoyed by this. &nbsp;Has anyone else had this happen?</P> Mon, 25 Sep 2017 06:01:33 GMT https://community.o2.co.uk/t5/Discussions-Feedback/Loss-of-coverage/m-p/1075105#M94926 Anonymous 2017-09-25T06:01:33Z https://community.o2.co.uk/t5/Discussions-Feedback/Loss-of-coverage/m-p/1075106#M94927 <P>Check here&nbsp;<A href="https://community.o2.co.uk/t5/Other-Products-and-Services/Self-help-guide-Is-the-network-down-for-me-or-everyone/ba-p/593752" target="_blank">https://community.o2.co.uk/t5/Other-Products-and-Services/Self-help-guide-Is-the-network-down-for-me-or-everyone/ba-p/593752</A> if no faults shown contact o2 4g coverage indoors should be better than 3G due to the frequencies used</P> Mon, 25 Sep 2017 06:05:36 GMT https://community.o2.co.uk/t5/Discussions-Feedback/Loss-of-coverage/m-p/1075106#M94927 adamtemp64 2017-09-25T06:05:36Z https://community.o2.co.uk/t5/Discussions-Feedback/Loss-of-coverage/m-p/1075108#M94928 <P>@AnonymousYour area is showing no problems...so it does need reporting</P><P><IMG src="https://community.o2.co.uk/t5/image/serverpage/image-id/21379i2E2BFA62AE2AC3F1/image-size/original?v=1.0&amp;px=-1" alt="TN4.PNG" title="TN4.PNG" border="0" /></P><P>If you download My O2 app you can report problems through that <A href="https://www.o2.co.uk/apps/my-network" target="_self">https://www.o2.co.uk/apps/my-network</A></P> Mon, 25 Sep 2017 06:41:41 GMT https://community.o2.co.uk/t5/Discussions-Feedback/Loss-of-coverage/m-p/1075108#M94928 Cleoriff 2017-09-25T06:41:41Z https://community.o2.co.uk/t5/Discussions-Feedback/Loss-of-coverage/m-p/1075109#M94929 Fringe 4g coverage could well give a lower signal indication than you had previously on 3G but 2g will give you the best signal indoors.<BR />Assuming you have WiFi at home for data just select 2g or GSM only when indoors.
