Issues with my new iphone 14

[adeiadey]

Good day 

I got iphone 14 yesterday and it's has been giving me a serious headache the connectivity is very bad both the wifi and hotspot, quick battery drain and overheating. I call the help line customer care to how to return and probably get iphone 13 pro back don't mind if it's going to attract extra charges because I have been using 13 pro max and is very okay.         d

Thanks

So you're using the old SIM, and it doesn't work in your new phone, but worked in your old one, @TheBud13?

Have you restarted your new phone?

Did you get the phone directly from EE?

Jon

[TheBud13]

Yes, and reset to NEW phone twice & to a Back-up point twice.

[Jon_K]

Do you still have your old phone, @TheBud13.

If so, can you try using your SIM card in it and let me know if it still works?

Jon
