We are planning to develop the push notification service for a telecom operator. But I haven't got any information whether the APNS push service is free of cost or should we make any payment?
My questions are,
Should I pay for using the APNS push service?
If operator want to sent push notification to millions of subscribers, should we pay to Apple or is it absolutely free? If not free, please share the URL where payment details are available.
Is there any limit for the number of notification sent or the number of subscribers?
Apple does not charge a separate fee for utilizing the push notification service.
Your only cost is a server that will be sending the push notifications to Apple. There are third-parties that provide this servers and there is a fee for that.
Answer for your question 1,2 and 3 is: Apple doesn't charge you for APNS - but you have to maintain a server for pushing.
Try these third parties for pushing,
PushWizard, a free and unlimited push service.
It can send 250 million push messages / hour
and PushWizard is free for unlimited devices, while other services can be very expensive if you have more, than 1 million users to reach at least ONCE per month.
Monopush, which provides a RESTful API and a lot of free push alerts up-front to handle the server infrastructure for you.
You need just copy and paste a few line codes to inside of your application and then magic will be started. After that you can start to watch, analyze, categorize your clients and you can send push messages to them as well as resource messages.
As mentioned above, Apple does not charge for the APNS
However, you need to maintain a 3rd party server for that, and sending notifications to millions of devices would require a lot of work from you.
There are some very good industrial solutions for iOS push notifications service that use APNS:
PushApps - free for 1M notifications per month, and unlimited notifications for 19.99 per month - here is the documentation
Urban Airship - free up to 1M notifications per month, afterwards you are charged per 1000 notifications
PushWoosh - free for 1M devices, premium plans are from 39 EURO
Diclaimer - I work in PushApps and also use their product in my applications for over a year now.
Please refer the following:
APNS is a free service. However, you need to maintain a server to send Push Messages.
Apple Local and Push Notification Programming Guide
There are many online servers which provide you free push services [for limited pushes/users/devices]. They do have plans depending upon the needs of client. Following are the few ones:
a. Parse Parse not available anymore. It is now acquired by Facebook. Read More Here
b. PushWizard
c. Xtify
d. SetUp your own push server - this tutroial comprise of complete end to end steps of how to send push messages to iOS Devices.
Hope this helps.
Although push notifications are usually send from 'servers', it is not necessary to own a server or to pay a service. Instead it is also possible to send pushes from your personal computer or mobile device. Especially for testing purposes, this is very useful. Try:
NWPusher
APNS-Pusher

I have developed an iOS app and have my server (just a couple of php files and a database) set up on GoDaddy.com.
Unfortunately GoDaddy.com does not allow me to send a push notification from its server because it requires to use a specific port.
I have users' device token stored in my database, is there any service online that I can use to send push notification with the device token I have?

I'm currently struggle with annoying store-and-forward function limitation of APNS. Here is a quote from the Apple docs:
If APNs attempts to deliver a notification but the device is offline,
the notification is stored for a limited period of time,
and delivered to the device when it becomes available. Only ONE recent
notification for a particular application is stored. If multiple notifications
are sent while the device is offline, each new notification causes the prior
notification to be DISCARDED.
I specifically make ALL CAPS for the keywords of my problem. In Google Cloud Messaging notifications service their store and forward function have much more capabilities:There is a limit on how many messages can be stored without collapsing. That limit is currently 100. If the limit is reached, all stored messages are discarded. - so Google service can store up to 100 push messages for a max time of 28 days. And in addition to this they have also coalescing (collapsible) notifications but for 4 different collapsible messages. And in APNS all we have is - one recent
notification for a particular application is stored - it is quite a limited behaviour for my app (I need to store at least four different push notifications while the device is offline at one given moment of time).
So I'm interested are there some ways I can improve store and forward capability of APNS?? Can I in some way make APNS to store more push notifications for a specific device?Or at least store several coalescing notifications as in Google collapsible messages? Some third party solutions or whatever? May be I missed something in APNS docs? I know we can orchestrate apple push notification on google platform - but I think it is not a solution because of its unjustified complexity.
As you found yourself in Apple's APNS docs, there is no way to store more than one notification per application for a single device. If you want to compare it to GCM, APNS server acts as if all notifications have the same collapse key.
No third party solutions can work around that, since Apple doesn't return an acknowledgment of delivery to the sender of the notification, so the server (whether it's implemented by you or by some third party provider) has no way of knowing which messages to store and resend (assuming that all the messages are valid and were not rejected by APNS server).
Apple Push Notifications are not intended to deliver important data. Their purpose is to notify the user of the app that new data is available at the server, which allows the app to load that data if the user chooses to open the app. That's the reason why they don't store more than one message per app for the same device.
I want to create an iOS chatting app using APNS. If I have 10,000 active and they are continuing chatting, will apple block my developer account ? Is there any limitation regarding this?
I would discourage you from using APNS as a backbone of an "chatting app".
If you need fast chatting functionality you should write your own TCP-socket based server.
If every-few-second syncing is o.k. you can get away with a HTTP-based server backend (but all the pull-syncing can be hard on network traffic - so TCP-socket is still better choice).
You could however use APNS for fallback - when your app on certain device is not responding (i.e. is not connected to server) you can send an initial message trough APNS (to wake up your app & to notify the user there is a message waiting for him).
As soon as the user opens your app you should switch back to your TCP-socket or HTTP request based server communication.
As for your question: no, Apple would most probably (one can never know for sure) not reject your app just because of using APNS for chatting. But note (as the others said allready): messages between two users will get "lost" if they would interact too frequently - see the link Roman Barzyczak gave you.
"If you are sending multiple notifications to the same device or computer within a short period of time, the push service will send only the last one."

but Apple wont block your developer account :)
You can use them for messaging but you are going to quickly find out that there is no guarantee they will arrive. This is known as the black hole of push notifications. ;-)
I like this answer here.
First try to use an APNS only solution.
Make your push notifications stateless (they only serve as "Hey you have some new stuff in the server").
So when the client gets a push notification it asks the server for new data (messages or other stuff).
Use OneSignal to simplify the code that sends push notifications (from the back-end). If a user in your app gets a message after 10 seconds he dose not care if you used TCP,socket.io or xmpp...
Even Whatsapp's messages can take couple of seconds to arrive.
A chat app is not a realtime game. A delay of couple of seconds will be acceptable by end users.
I'm wondering if there is a limit to the number of apple push notifications we can send to users at once?
Can I send 100,000 push notifications at once using the APNS service?
If you are sending multiple notifications to the same device within a short period of time, the push service will send only the last one.

Look "Some Notifications Received, but Not All" in that documentation.
Apple's Tech Note was recently updated to address this question :
There are no caps or batch size limits for using APNs. The iOS 6.1
press release stated that APNs has sent over 4 trillion push
notifications since it was established. It was announced at WWDC 2012
that APNs is sending 7 billion notifications daily.
If you're seeing throughput lower than 9,000 notifications per second,
your server might benefit from improved error handling logic.
There's no limit on how much notification you can send to Apple APNS server but reminder to avoid using allot of connection because Apple may ban your IP if he think you are doing a DDOS attack.
Also if a user is offline (iPhone out of signal) only the latest push notification will be in saved in apple's APNS server
Yes, you can!
You can also use 20 connections max for the sending of data.
Is there any limits/restrictions about amount of notifications sent to the APNS in time range?
For example - can I send 100,000 messages for 100,000 devices (one message for one device) in one hour to notify them about new content available to purchase via in-app purchases ?
Found nothing about any restrictions in the manual.
I don't think there is a restriction for number of messages sent in a time frame. But I guess in your case, it is unclear, if it violates rules stated in review guidelines 5.6 and 5.8
5.6 Apps cannot use Push Notifications to send advertising, promotions, or direct marketing of any kind
5.8 Apps that excessively use the network capacity or bandwidth of the APN service or unduly burden a device with Push Notifications will
be rejected
