I upgraded from text and web to the above this afternoon using live chat and a guru. Everything gone fine and am now on the new tariff as My O2 App shows. However my Sony Xperia Z3 Compact phone still only shows H+ for mobile data and not 4G. I have obviously gone into 'Settings' and ticked in mobile networds 4G(preferred)/WCDMA/GSM etc. and then re-started my phone but nothing changed.
Another quick online chat suggested I remove and re-insert the SIM card but wasn't then sure whether the phone should be off or instandby etc.
Solved! Go to Solution.
Text the word "active" to 2020 and save the settings you get sent back.
Thanks but which settings on my phone does it alter, doing that?
The network data settings.
Well, I fiddled with my phone's settings again last night (having done this several times already) and went into Mobile Network setiings and changed it to 4G (preferred)/WCDMA/GSM, as one would and then put the phone in Airplane Mode and then back off again. I then turned on my mobile connection and Lo and behold the magic 4G symbol appeared at the top of my screen. I now have blisteringly fast mobile internet connection in excess of 20Mbps!
