Mobile Data

[Jonosaur]

Hi I have an issue where I have 2 or 3 bars of 4g, and my mobile data won't even load a simple web page.  This happens in numerous locations.  Very frustrating every time I need to use it it fails me.

This could be for a number of reasons. It may be the area of congestion  (not uncommon on O2)

Have a look at these guides first

Guide: How can I sort out my network issues? 

Guide: Is the network down for me or everyone?

check the service checker https://status.o2.co.uk/ or Guide: How can I sort out my network issues? Follow the guide if this continues contact O2 via social media or 202 or agents within the myo2 app

And finally, in your phone SIM network settings, step down from 4G to 3G (sometimes called 3G/2G) - it will buy you a bit more download speed if 4G signal is spread too thin, @Jonosaur 

And download and register this O2 app, which will keep you and O2 up to speed, no pun intended, on the poor performance in your area. https://www.o2.co.uk/apps/my-network

Good luck!
