Unfortunately, it's not possible to download your SOL ID card without your control number. The control number is a unique identifier that links your personal information to your SOL account.

Here are some steps you can take to retrieve your control number:

1. Check your SOL account: Log in to your SOL account and look for the control number. It's usually displayed in the profile section or account settings.
2. Contact SOL Customer Support: If you can't find your control number, reach out to the SOL customer support team. They should be able to assist you in retrieving it based on your registered information.
3. Provide Necessary Details: Be prepared to provide your name, registration number, or any other relevant information that can help them identify your account.

Once you have your control number, you should be able to download your SOL ID card from the official SOL website or through the designated portal. The process may involve logging in to your account and accessing the ID card download section.

If you continue to face difficulties, don't hesitate to contact SOL customer support for further assistance.
