If you want to add push notifications to your app you have two choices. You can either program the server-side components yourself or you can sign up with a push notification service provider.
The alternative is a Push Notification service provider. With a good service provider you should have the bandwidth you need and be able to push messages to your app running on all the popular mobile platforms. The service provider will also have features like customer targeting by location or some other group criteria.
