iPhone 11 cellular data not working after iOS 18.6.2 update

Hello everyone,


After updating my iPhone 11 to the latest iOS version, my cellular data stopped working. I've already tried the following steps:


  • Replaced my SIM card with a new one
  • Reset network settings
  • Reset all settings
  • Even did a full factory reset


The signal bars show full, and the data logo (4G/LTE) is visible — but everything just keeps buffering. I can't use mobile data at all.


Has anyone else experienced this? Any ideas on how to fix it?

It's not always the iOS update's fault!  Many things can cause phone problems.  If you tell people you think it's an iOS update, it might make it harder to fix or find a solution for the real issue.



Remember, the right question often leads to the solution!



Was/Is your device Jailbroken? If that's the situation, please be informed that attributing the issues to iOS updates may not be accurate.



iOS updates aim to enhance user experience, boost security, and fix bugs rather than disrupt core features. The majority of the issues after updates might stem from underlying, unmentioned factors. Updates won't typically alter personal data but may refine settings or features. Backup before major updates for safety. Review Apple's update details and backup advice for a smooth process.


Kindly consider checking your settings and addressing any device issues before attributing the issue to external factors. This could be a pure coincidence that the iOS update affected the iPhone functions.


Before initiating a standard iOS update, it's advisable to create a backup. Have you completed this step? If yes, proceed with the restoration from the backup.

BlacKitten31 ~ Your iPhone 11 could be 6 years old and the long process of applying an iOS update to an iPhone with a weak, aging battery can be the proverbial "straw that broke the camel's back." (And a weak battery can cause connectivity issues.) So...


Does your iPhone 11 still have its original battery?


And what's the Maximum Capacity % here?...
