Will i get notified if pin cards are swapped?

[dimpetrov2018]

I am not sure if this is the right section of the forum but i will still ask here. The question is a bit odd but i struck me if such scenario be possible. Lets assume that you have your SIM card pin disabled- to pin code is requested when you turn on the phone. If someone gets my phone, pulls out your sim card and place other sim card that also have it sim card pin disabled, will i have any hint when i take back the phone that the sim cards have been swapped? Like message or something? Or sipmly i will ublock my phone and keep operating with my new card without any notice that sim has been change? I left my phone to a friend (locked by passcode) for couple of minutes then i took it back, i used it but without making any calls for couple of hours and stuff like that then i left it again for couple of minutes. Now my phone bill shows services i never used and unless i did something on my own it has to be him. Since he only had my phone or couple of minutes i assume he removed the sim card and gave me back my phone with other sim card? And later the same day he switched them back. Is this possible at all will iphone allow it? Thanks

One more thing to consider- i only used my celluar network at that day because i was not in my house. So if he swapped the cards would i have recived notification about using other celluar network or something like that?

I don't know of any way to be notified when this happens.

You would not get a notification of this happening in any such way. The SIM card changes the phone number on the phone and, if unlocked or on a supported network, what carrier is being used.
