If a SIM card is hacked what is first thing one can do
can an Apple ID be hacked ?
Question marked as
SIM cards cannot. be hacked.
An Apple ID can be compromised, and the first thing to do then is to change the password for it, and possibly enable 2 factor authentication if it's not already on.
See here for details: link-> If you think your Apple ID has been compromised - Apple Support
and here: link-> Two-factor authentication for Apple ID - Apple Support
With that said, why do you think either of those is hacked?
