My wife's iphone is on my account. She has never (like so many people) had a PIN for the SIM on her iphone 11. Now, reading of security issues, we want to set one on her phone (I have always had a PIN for my SIM). However, we are one attempt away from locking her phone as we have obviously got the procedure wrong twice. What is the correct procedure please? The phone itself has no guidance at all.
I opened Settings/Mobile Data/SIM PIN on her phone. Under SIM PIN there is no information as to what is required - it just says SIM PIN and I checked the box as this is the first PIN on this phone. Thereupon, it displayed a new screen requiring entry of the PIN with no indication as to whether it needs the new PIN, an old PIN (?0000 as there has never been a SIM PIN) or, indeed, the main phone PIN (6 digits). When she input the new PIN she wanted, we were told we had two more goes before locking. She tried the main iphone PIN and we had one go left. So I am asking for advice as we have only one attempt left and absolutely no information as to what we are expected to do to set a SIM PIN for the first time. I suspect that the entry we were addressing was to lock the SIM, rather than set the PIN. HELP!
