I didn't receive a text message during my medical examination in America.

Hello, you are a liar. In fact, these are very easy to identify. Don't trust anyone who asks for money after receiving such short messages. Those who have links must be infected by scammers. Winners should know that there is no pie in the sky. Just like medical text messages, if they want money, they can call the hospital to ask if it is true or not (think about whether they have a medical examination). Doing so will greatly prevent fraud. In addition, you can download third-party security software, such as Teng Xun Mobile Manager, to shield the harassment of these spam messages. If you have any questions, please keep asking.
