iPhone Call Failed Problem, How to Fix?

Call failed problem distribution many time since I brought this iPhone 11 (from sep 24, 2022)

I’m using Jio prepaid eSim

I changed to eSim on January

This problem is already in physical sim but also continues in eSim also

Currently, I’m using one Jio prepaid eSim and Jio postpaid physical sim

hi bro, have you updated to latest iOS 16.4.1?

Yes, updated

it is recommended to get it checked with apple service center or apple support once bro. diagnosis is required to check whether any problem is there in modem or hardware level. If its software issue latest update should have fixed or apple service center will do iOS Restore once bro. that will help to understand whether its software or hardware problem.
