so, you got a new sim card and a new phone now?
If you are unable to login as you don't have a phone to receive the 2FA code: On the screen it is expecting you to enter the code, click Didn't get the code? or Resend code and then choose Send email
If that does not work, you will have to message support and ask them to help to login and change the sim card as well. Message them here:
