SlingPlayer Mobile is available for free as a 30 day trial. But after those 30 days are up, you need to purchase a Registration Key to continue watching TV on your phone or mobile device. Here's where you'll find that Registration Key after you have purchased a Registration Key for SlingPlayer Mobile. If you haven't purchased a key yet, you can do that at the Sling Media Store.

Finding the Registration Key can be a bit confusing, at it has several different names, depending on where you are in the purchase process. It is sometimes referred to as:

• Registration Key
• Serial Number
• Digital Rights

All of these terms mean the same thing! When you see any of them, the series of letters and numbers that follow is the key that will unlock your copy of SlingPlayer Mobile.

If you are looking on the order confirmation web page presented right after your purchase is complete, it called "Serial Number."

Compare that to the text from the confirmation email received for that same purchase. The same key is labeled "Digital Rights."

So, if your purchase is complete and you are looking for that key, look for the confirmation email that came from the Sling Media Store Online. Near the end of that email is the section about Digital Rights. That is your Registration Key.
