I lost my mobile phone and changed it. Can the original mobile phone card still be used? Can you receive the message?

Don't worry about whether the original mobile phone card can be used after you lose your mobile phone. As long as you want to reissue a new mobile phone card, the original mobile phone card will become invalid by default, and you can't use it any more, and you can't receive any information and make calls.

Pure hand-beating, I hope I can help you solve the problem, seek adoption and praise.
