I travelled to Spain last October - my phone connected to the wi-fi where i was staying but my iPad would not so I made my phone into a hotspot & connected via that to use my iPad. I also connected to roaming data services. I haven't been able to connect to a mobile network since returning to the UK. I have tried resetting the giffgaff APN settings several times. I have tried removing the giffgaff profile & re-installing. I have upgraded iOs to 12. Nothing has worked. My iPad has used some data from my gigabag but very little - I certainly cannot use Safari when not connected to wifi, just get the 'Could not activate mobile data network' message. Hoping someone can help please !

Thank you sloz,
I do get a 4G or 3G symbol when I turn off 4G - interestingly my 3G connection is working!
I then removed all profiles - there was only one i.e. giffgaff - reset network settings - then i had to Install the giffgaff APN settings again. 4 G still does not work. Changing the apn to Mobile.o2.co.uk doesn't make any difference, 3G works but 4G does not.
I don't have an iPad, but from feedback, others have found that 3g works with both the giffgaff and o2 apn
4G only works with the o2 apn,
