Push Notification for Android and iOS

I have an app with a user base of almost 80,000.

  1. Is there any free push notification plugin??
  2. Is Ionic push notification will work if the app is close?

Need suggestion…!

Thanks.

you can use onesignal for your push

You can check the link for more details https://documentation.onesignal.com/docs/ionic-sdk-setup

Hi,
you can try to using firebase push notification or onesignal push-notification.for ionic 3 application.May be it will work try it.

Is Google Firebase also supports iOS?
