I need help. Old SIM card  not working in new phone, or other phones. I have, several times, done absolutely everything that  was recommended to resolve this issue, network resets etc, checking apple status.  So I thought I’d try and get a replacement SIM card but AI  was not helpful. Plan B - get an eSIM. Everytime I try this , it sends a code to the phone number that I can’t access. Can it be sent to my email address? Tried calling. I spoke to a lady who then transferred me over to IDMobile, but it turned out to be the vulnerable persons help line , for which I am not registered and the call was cut off.  Please can someone give me access to my phone again. This is a nightmare.
