Can someone check the phone bill and text messages with my ID card?

Anything will do. You can check all the documents related to your ID card.

Inquire about information, people will not check the cardholder. Only those who need to copy their ID cards when opening an account.

As long as the signature is not involved, the signature is the proof of the actor. I don't believe his handwriting will be the same as yours.

Privacy? I lost my ID card. Get everything ready.
