I cannot host my own server for iOS push notification because the router is limited by Admin.
I want to learn from scratch so I don't want to use Parse or quickblox. Where and how can I know which PHP hosting plan support iOS push notification? Is there any free hosting available?
From Apple, the server need to allow inbound and outbound TCP packets over port 2196. I don't think regular hosting plan will list out this information.
When I learnt Android push notification, I can easily find a hosting plan with CURL. iOS is a bit demanding.
