I recently purchased an iphone 13 pro max from Apple, and put my sim into the phone and it worked except 5G never connected. I know I get 5G in my area as my Mums phone gets full bars all of the time. I put her O2 sim into my phone and 5G connected instantly, confirming that my phone was working fine. I have spoken to O2 on multiple occasions (quite literally 10 times over chat and call in the last week) and they have either told me its working fine, or that I need a new sim. Every advisor has sent me a new 5G sim, and I have done 4 sim swaps since last week, with no 5G at any point of time. I work in London - and 5G has also never connected there anywhere during or travelling to work (colleagues on o2 were getting 5G signals on iphones) I was told there were issues with masts in certain areas in one of my calls which clearly is not the reason I am not getting 5G. I had one advisor do something on my account and change my tariff without my consent also, and the next advisor claimed I was never on my initial tariff (25GB) despite me having evidence of an email from O2 confirming my tariff when I changed over to it. On top of this, when I was sent a replacement sim someone had turned the sim I was using off during easter weekend, so I had no signal for 4 days. I initially called to get 5G activated, but now have been switched tariff, have no 5G and lost signal for multiple days.
