If anyone from the UK is having this problem then here’s how to fix it:

You will need to go to - Settings > General > Network > Cellular Data Network...

Under ‘Cellular Data’ you will see that ‘APN’ says ‘idata.o2.co.uk’... If you are on Pay & Go then ‘APN’ needs to read ‘payandgo.o2.co.uk’ or if you are Pay Monthly then ‘APN’ needs to read ‘mobile.o2.co.uk’... There is no need to change either ‘username’ or ‘password’... Also you can leave the ‘Visual Voicemail’ settings as they are...

Thanks so much, that did work for me and enabled my iPhone after 4 months again to the internet!
