Cellular Data and SIM and E-SIM Not Working – iPhone 14 Pro on iOS 18.4.1 (Tried DFU, iTunes, SIM Change, Network Reset)
Hi everyone,
I’m running into a persistent issue on my iPhone 14 Pro (iOS 18.4.1) where cellular data becomes completely unavailable.
Here’s a detailed breakdown of the problem:
The cellular data section in Settings appeared blank, and I was unable to access mobile data at all. The device doesn’t seem to recognize or connect to any cellular network with the SIM or esim and shows no service.
To troubleshoot, I tested multiple SIMs:
• The “faulty” SIM works fine in other phones.
• I even tried a brand new SIM card, as well as others from different carriers.
• All of those SIMs work without issue in other devices, but none of them provide data or proper cellular recognition on this iPhone.
So this is definitely isolated to the phone itself, not the SIM cards or carriers.
Here’s what I’ve already tried:
• Reset Network Settings
• Tried new and known-working SIMs
• Updated via iTunes/Finder (not OTA)
• DFU restore and clean setup (without restoring a backup)
• Reinserted SIMs with/without Wi-Fi
Another issue compounding this is that when trying to update iOS over the air, I consistently get an error , even though I am connected to Wi-Fi.
This leaves me stuck:
• Cellular data doesn’t work with any SIM.
• OTA updates are blocked.
• Full DFU restore didn’t resolve the issue.
Has anyone experienced a similar issue? Is there a fix, or should I consider this a potential hardware or baseband firmware failure?
Any help or insight would be greatly appreciated.
Thanks!
