Jedi survival wechat changed its mobile phone number, and the account number is gone.

You can have it back. As long as your mobile phone number hasn't changed, you may log in with the verification code by binding the mobile phone number of the Jedi survival game, or exchange the verification code for the bound mobile phone, so that you can use the new mobile phone number after logging in to the game. If the previous mobile phone number is useless or lost, you can appeal to the account through the bound ID information when registering the account.
