Hello @Taydillx ,
Welcome to the community,
EHas it ever worked and how long have you had the phone?
When I had a problem with my IPhone 12 Pro Max, I spoke to Apple and sent it to them and within a week I got it back at no cost to myself.
You may want to ring customer service, but otherwise ring Apple, they are very helpful.
If you have another phone, put your SIM card in it and then you can call customer service by dialling 150 or ring Apple, as you have tried the reset and it has not solved the problem, it looks like a faulty phone, or rather a software issue.
To contact EE customer service dial 150 from your mobile phone or ring customer service for free using Skype or another phone: +44 800 079 8586 or +44 800 956 6000.
