All of my friends have no issues connecting to 4G to do the quiz, but my phone is lucky to get H+ or 3G even. Is it just my phone or is Sony just bad at this. Really disappointed with this device to be honest. Wish I'd stayed with Samsung!</P> Wed, 26 Jan 2022 22:20:27 GMT https://community.o2.co.uk/t5/Android/Sony-Experia-1-II-Mobile-Data-Connection/m-p/1527057#M78779 Davey66 2022-01-26T22:20:27Z https://community.o2.co.uk/t5/Android/Sony-Experia-1-II-Mobile-Data-Connection/m-p/1527124#M78782 <P>Were your friends on o2 as well or just you <a href="https://community.o2.co.uk/t5/user/viewprofilepage/user-id/1955961">@Davey66</a>&nbsp;?<BR />Did you get the phone from o2, and did it come with a new sim?
