I have an error that says Cellular data issue detected. It said I needed to update IOS to fix, upon updating it was still broken.
I have cleaned my SIM card, reset my network settings, fully restarted my phone, and other options.
iPhone 7, iOS 15
I have cleaned my SIM card
How did you do that? Cleaning with what?
1.
Remove and reinsert the SIM card.
If it doesn't help contact your carrier, maybe the SIM card is damaged, ask for a replaced (new) card. Normally it is free.
Also ask to check if the SIM tray is bent, as even a tiny misalignment can cause the SIM card to not fully connect with the internal contacts in your iPhone.
