How to get to Sim application/toolkit on iOS 13/iPhone 11
I am using iPhone 11 Pro Max with AT&T eSim and an Indian (Vodafone) nano SIM. I am trying to get to the SIM Application/Toolkit to configure the physical SIM. I can't find this anywhere. Searching the web, people seem to have been able to find this in iOS 12 under Settings>Mobile Data which is not something I see on iOS 13. Can someone help me find this? Thanks.
