Sony now offers seven-day trials on PlayStation Plus Extra and PlayStation Plus Premium.
Taking out a subscription to Extra (EUR 13.99 per month) and Premium (EUR 16.99 per month) now includes said test phases.
Not available separately
But keep in mind that these test phases are not available separately. Basically, you have to sign up for an Extra or Premium subscription, then you get this test option.
At the end of this seven-day trial period, the normal subscription begins. You can see the corresponding options if you want to take out a new subscription. Existing subscribers do not have this option.
More on the subject:
As Sony emphasizes, you can cancel the respective subscription before the trial period ends and the actual subscription starts if you don’t want to pay anything.
If you haven’t had a subscription yet and would like to take a look at the individual stages yourself, you certainly have the opportunity to do so.
