I wish I hadn’t updated it to ios14. It’s been 5 months since I have no network on my iPhone 11 Pro. I had only used it for few months before this happened. I thought it was my SIM card problem, but I tried using my SIM card on another phone and it worked. So, it’s the phone problem. I’ve tried everything, even factory reset, and it still doesn’t work. Some people have mentioned that their phones are fixed by removing their VPN, However, I don’t have any on my phone. I hope Apple would give the solution or at least let us downgrade soon. Because it’s so inconvenient not having network and have to connect to wi-fi all the time. Basically my phone now is just a camera.
