Network Data does not work consistently on new iPhone 15 Pro - 4th Sim Card.

[TuckerKyle]

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?

This is not a new issue to O2 and seems to be caused by doing a sim swap.

The only fix we've found is the get O2 to disconnect and reconnect your account.

You may have difficulty in getting customer services to understand this request though.

Great, I did read that elsewhere. The O2 customer service is awful. Can they do this in the shop? I may just have to end up leaving them.

Yes you can @TuckerKyle - just take some photo ID to your local store and they can provide a replacement sim.

Unfortunately not @TuckerKyle 

You'll probably need to get customer service to escalate it to tech support to do it for you.

@MI5 Thanks for the reply. If I was to phone up and change my number, would that be a work around instead of explaining and asking them to disconnect then to reconnect me to the network?

@TuckerKyle 

I have nothing available to answer that unfortunately. No one has tried it as far as I know.

I have exactly the same issue. i went to Apple store and they wiped everything and now I have to put my app one by one but I found that I still have a same issue. I think I am leaving O2 at the end of this term after being with them for 20 odd years.
