Provisional push notifications appear silently in the user’s Notification Center but not on the lock screen. This type of pushes doesn’t need to be allowed by a user explicitly: you can start sending them as soon as a user installs and launches your app.
However, users still can subscribe to your prominent push notifications: when opening the Provisional Push, they have two options to choose their experience – to keep pushes in Notification Center without alerts and sounds or allow you to send pushes prominently so that they appear on the lock screen.
Provisional Pushes are designed to let users make informed decisions about whether they’d like to receive notifications from your app. As the APN native subscription request is shown to users only once and to subscribe later, they should go to their phone’s system settings, and some users might not subscribe since they aren’t aware of what value they get with your pushes. Provisional Pushes give users this understanding: they can see what content you deliver in push notifications and decide whether they need to be notified about this content prominently.
Please note that Provisional Pushes, when implemented, replace the native APN prompt, which means users cannot subscribe to prominent notifications until they open their Notification Center and choose to receive Provisional Pushes as prominent ones.
