Wrong sim type selected after Android software update

[Android Central Question]

Android upgraded, and afterwards it asked whether my sim card was postpaid or prepaid. I selected the wrong option and now my data doesn't work.

How can I change my choice? Is this an Android setting or do I need to call my network operator?

Welcome to the forums. That sounds like a carrier-related setting. I'd recommend you to contact your network operator and see if they can assist you.

Just in case, do you have an app called SIM toolkit? If so, see if it includes an option to change that choice.
