Undegraded to the new iPhone 15 Pro. My first upgrade since 2016! Ever since my network has not been working correctly. WIFI works fine but when I leave the house the Mobile Data drops off. I proceeded to swap the sim but they suffered the same issue. I had to buy a pay as you go sim as I was going away for the weekend. At first I put it in my old iPhone but decided to see what would happen if I put it into the new phone. It worked fine without a hitch. This ruled out the phone being the issue (I think) I then went back to the o2 store as I thought it must just of been a couple of faulty sim cards. However the same issue is now happening.
O2 customer services are awful these days and I actually had a technical support chat who said that when I leave a WIFI Network I have to turn the WIFI off for my mobile data to work.
Side note, in order to get the Mobile data to work I have to airplane mode off and on. Turning the Mobile data off and on does not seem to work. One thing I have noticed is that 3G doesn't seem to appear at all on the pay monthly sim cards...? Is the network dropping to 3G but the sims arent active on the 3G?
