I forgot my service password when I ran a card in a different place, and my mobile phone card could not receive SMS and phone calls. I want to try changing my card and bring the original one, Ben?

First of all, if you want to change the service password, you can directly call the manual customer service to change it. If the mobile phone card can't receive the message, you can only go to the business hall. But you don't know the latest phone number, so you are in trouble. Basically, to change a card now, you need to say a few phone numbers that you have called, that is, the most familiar numbers, and five is enough.
