The fact the sim works in other devices doesn't help you much. Your carrier needs to provision your account on your current iPhone if you can't access cellular data there. If the update caused this, it would cause it for everyone, but it didn't. This forum would be flooded with complaints if cellular data stopped working after iOS 26.2, but it's not. Carriers are the worst at helping their customers. Elevate your issue higher up the tech support ladder with your carrier.


Things you can try on your own:


  1. Force Restart your iPhone (something I do after EVERY iOS update) --> Force restart iPhone - Apple Support
  2. Reset Network Settings --> Open the Settings app, tap General, scroll down to and select Transfer or Reset iPhone, then tap Reset. Choose Reset Network Settings (Note: Doing this will require you to enter the password for Wifi networks again).
  3. Read this --> Use cellular data on your iPhone or iPad - Apple Support
