This needs to be canceled, which means you won't use the number in the future! You can take your valid ID and go to the business office to cancel the number. However, you can only cancel the number in advance, and wait until 31 days before you can cancel the number, and then you can take out the money, of course, you can also transfer the rest of the money to other numbers! If you've applied for a phone bill refund or something like that, and the money hasn't been refunded yet, then there's no way to get the money out! But you can take out the fees you deposited yourself normally!
