A. Ensure that you are signing up for the free trial using a valid email address and payment method. Sometimes, using a different browser or clearing your browser's cache can help resolve issues with the signup process. If you encounter an error, try accessing the Sling TV website in incognito mode to avoid any browser-related issues.

B. Check if you have previously used a free trial with Sling TV. If you have, you may not be eligible for another trial. In this case, consider subscribing to a low-cost plan to test the service.
