Sim problem

I’m using iPhone 13 (iOS 16.3.1) with 2 SIM cards. When I am talking over the phone using the Primary Line, the secondary Line will turn to No Service. Anyone having the same problem? Thanks!

That is not a problem. It is normal and expected behavior. Your iPhone is Dual SIM iPhone whereby both lines can be on standby to connect simultaneously however both lines cannot be active (connected) at the same time. When your iPhone is connected to the cellular networks and you take a call on one of the lines, then the other line will not have service for the duration of the call.
