I don't know my card number. How to judge that your mobile phone card has no contract?

If you don't know your mobile phone card number, but want to judge whether the mobile phone card has a contract, you can do it in the following ways:

1. Go to the local operator's business hall for consultation, provide your own identity information, and see if you can find out whether the mobile phone card has a contract.

2. Call the operator's customer service phone and ask whether the customer service mobile phone card has a contract and how to inquire about the contract information.

3. Open the operator official website, log in to your account, and check whether the mobile phone card has a contract.

It should be noted that different operators may have different definitions and regulations on contracts, so the above methods may not be able to completely and accurately judge whether the mobile phone card has a contract. It is recommended to know the relevant laws and policies of local operators before making a judgment.
