How to activate it? I applied for Unicom Star Pink Card online, and the number is 10+05.

You can carry out real-name authentication in the official account of WeChat Star Pink Card Assistant! Please enter the official account of Star Pink Card Assistant WeChat-Open-Open Activation; Tip: Users can also receive an activation prompt message after the mobile phone card is shipped, and click the link in the message to enter the activation page. It must be activated within 20 days from the date of receipt (including today). After successful activation, it can be used normally.
