Yes, you can try PlayStation™Vue with a free trial. One free trial per customer is available for 7 days, and can be enjoyed immediately after signing up for a subscription.
The first time you sign up for your package of choice, you will receive a 7-day free trial. You can cancel the trial at any time. If you do not cancel before the end of the 7th day, you automatically begin your monthly subscription and you will be charged a monthly fee based on your chosen plan until you cancel. There are no penalties for cancellation and you will still have access for the rest of the month already paid for. To cancel, go to Settings, select Subscription and click the cancel button or login at www.psvue.com and select My Subscription > Unsubscribe.
