If you experience:
- device: iPhone with iOS 14.5 or 14.6
- plan: prepaid
- symptom: After you updated your iOS to 14.5 or 14.6 the cellular data stopped working. Both text and call work, but cellular data (LTE) does not work. You can see the LTE logo and have strong signal but there is no cellular data connection.
Here is the solution that works for me:
Update your iOS to beta version which is iOS 15 now through Apple Beta Software Program. Just search “Apple Beta Software Program”, go to the website and follow the guide.
