cellular data issues

I have this issue too, but also have issues with some websites in safari. Also App Store doesn’t load. I’m in the UK, if that helps anyone out there.

So far I’ve tried—

• Clearing Website data,
• Removing and reinstalling apps,

neither of these do anything.

The only thing that works, but for a very limited amount of time, is resetting Network settings.

The phone is a 64GB XS, and currently has 21GB free, running latest update of iOS, and I always close all apps down so its not a RAM/Memory issue unless there’s a serious hardware fault.

I think its probably a bad update last time round. Let’s hope there is a 15.6 to fix it.

Check under Settings -> Cellular -> find the app that isn't working with Cellular data and check if its switch is On (green).
